In the various seasons (spring, summer, and fall) during the year, pollen grains are dispersed from trees, weeds, and grasses. These pollen grains travel on air currents to fertilize other plants. Inhaling pollen, in some people, can trigger seasonal allergic rhinitis which is also called pollen allergy or hay fever. In this condition the mucous membranes in the nasal passages inflame, which causes swelling, sneezing, itching, irritation and a runny nose.
Allergy seasons are:
• May – July/August – Grass pollen:
• Feb – June – Tree pollen (depending on whether allergic to early or late flowering trees)
• August – September – Nettle/weed pollen
Hay fever symptoms can continue all the year round and may also occur from indoor allergens like house dust mites, pets and possibly indoor moulds.
Hay fever is actually an attempt by the body to rid itself of allergens but the immune system overreacts and releases chemicals which cause inflammation, causing:
• Itchy, watery, red eyes
• Frequent sneezing
• Constantly dripping nose
Sufferers, when afflicted with this condition, have to struggle to breathe through their nose. Symptoms are often quite bad in young people and tails off in later years as the body adapts. Studies have shown that hay fever can severely affect the quality of life, disturb sleep patterns, impair daytime concentration and work performance.
Pollen once released from trees, weeds and grasses, ride on air currents with a mission to disperse and fertilize other plants. However, they rarely reach their targets. On the way they get into human noses and throats, triggering allergic reactions.
Pollen is one of the most pervasive things that can cause an allergy and cannot be avoided. Many allergy causing foods, drugs, or animals can be largely avoided but insects and household dust are inescapable. However, short of staying indoors, there is no foolproof method of evading windborne pollen. Nonetheless, ways have been established that help ease the symptoms of hay fever. Moreover, scientists are working to find better approaches to allergy treatment.
Research has helped provide a better understanding of the causes of allergy, improve the methods for diagnosing and treating allergic reactions and thereby eventually preventing them. The common signs and symptoms of pollen allergy are:
• Sneezing, the most common, may be accompanied by a runny or clogged nose
• Itching eyes, nose, and throat
• Allergic shiners (dark circles under the eyes caused by restricted blood flow near the sinuses)
• The “allergic salute” (in a child, persistent upward rubbing of the nose that causes a crease mark on the nose)
• Watering eyes
• Conjunctivitis (is inflammation of the membrane that lines the eyelids, causing red-rimmed eyes)
In a pollen-sensitive person, as soon as the allergy-causing pollen lands on the mucous membranes of the nose, a chain reaction occurs that leads the mast cells in these tissues to release histamine. This potent chemical dilates the small blood vessels in the nose; causing the fluids to escape through the expanded vessel walls, which in turn results in swelling of the nasal passages as well as nasal congestion. On the other hand, histamine also causes itching, irritation, and excess mucus production. Similarly, other chemicals like prostaglandins and leukotrienes also contribute to allergic symptoms.
Some people with pollen allergy also develop asthma, a serious respiratory condition, which can eventually become chronic. Symptoms include coughing, wheezing and shortness of breath due to a narrowing of the bronchial passages and excess mucus production.

Should Toddlers Have Allergy Shots?
There has always been fear connected with allergy shots for a toddler or infant. This fear has its roots in the occasional but rare severe reaction to the allergy shot. So what are the benefits and what are alternatives
If the cause of an allergy can be detected at the outset then this of course gives the best means of defense by training the toddler to avoid contact. There are some difficulties when toddlers are outside in the open air where pollens are airborne.
With the indoor allergy causes such as molds and dust mites etc the obvious solution is to clean the house and rid the area of these causes. Yet even here there are exceptions because cleaning wont do the whole job when the smallest particle of the allergy substance will do harm to the super sensitive toddlers skin or airways. There is the further issue of insect bites and bee stings which cant always be anticipated. In such cases there needs to be planning ahead to know exactly what to do especially with any life threatening bite or sting. Added to all this is the whole matter of allergy to foods and that’s a whole other matter.
Medications for allergies are common these days and are very effective in reducing allergic reactions. Scripts containing Claritin and Singular are widely used in prescriptions these days and with the toddler must of course be administered in the correct proportions according to a doctor’s direction.
Having prescribed shots administered for a toddler are universally accepted as safe and can even have the effect of helping the young child develop immunity over time. These shots are generally most effective when given over a period of several years, which enables the Childs body to slowly develop immunity with risk.
There are two phases in the administering of allergy shots. The ‘buildup stage” where small but increasing doses of allergen are given so that the toddlers system adapts to the allergen without a reaction. These shots may be three times a week up to seven months and it has the same effect as a vaccination program
There is a time of maintenance now that follows this is to complete the immunizing process and give an close to permanent benefit. When the body has developed a high immunity to allergen then this is to be followed up with monthly shots over three years
If there are any side effects these will be minimal and can range from a mild irritation at the place of the shot to at worst colds or skin hives. There are however some rare but very serious reactions such as anaphylaxis and if this occurs which is indicated by shallow restricted breathing you need to get emergency help from doctor or hospital. If there is any history of anaphylaxis in the family or any previous testing for it then the antidote injection needle can be supplied to have on hand. The substance is simply adrenalin, which immediately relieves the symptoms
To give a toddler the allergy shots is a serious commitment and a visit to local doctor before application for some advice will be well worth your peace of mind. However to ignore the issue is to possibly leave your toddler at risk as in the case of bee stings and other insect stings, which can give strong reactions. To have a life long benefit for the toddler into his or her adult years is the benefit gained.

Food Contaminated With Toxins.Difficult Bowel Syndrome.
Food allergy crops up when the immune system incorrectly strikes a food protein. This leads to the improper digestion of the offending food, which in turn triggers abrupt discharge of certain chemicals, leading to an allergic reaction. The symptoms of these allergies can branch out from mild to very serious. Here are some of the most common food allergies symptoms:
Remember, separate foods are associated with separate food allergies symptoms. For example, you will feel wheat and chocolates mainly cause headaches. Here is a list of symptoms and the food that cause them:
Asthma: eggs and flour
Allergies in Children: Wheat, milk, eggs, colas, beef, peanuts, chocolates, rye,
Headaches/ Migraine: Alcohol, peanuts, chocolates, milk, eggs, dairy products, tomatoes, wheat, chocolate
Eczema: oranges, tomatoes, grapes, Eggs
Nasal Allergies: chocolate, Milk, wheat, nuts, colas,
Hives: mango, Strawberries, tomatoes, eggs, chocolate
Fatigue: wheat, corn, milk, Soya
Apart from these, Peanut food allergy is known to be the most common and the most fatal food allergies. Unfortunately, since the past few years the prevalence of this allergy has only doubled.Hence, If you feel that your body reacts abnormally after peanut consumption, immediately stop and go to the doctor for further clarification.
Another very common allergy is the allergy related to Egg. If you refer to the above-mentioned food allergies symptoms, you will notice that most of them include eggs. Hence, if you are one of those people who have an allergy from eggs then make sure you check the Food labels of the products that you eat.
Causes Of Food Allergy
There are several causes for food allergies to develop.
If an individual consumes a food that is contaminated with pollutants, then the body will react by generating antibodies to get rid of the food inside the system. This abrupt response of the body can cause an allergic reaction and symptoms.
Difficult Bowel Syndrome
It is a known fact that more than 6 percent of the people suffer from a difficult bowl syndrome globally. A bad bowl can be very treacherous and can cause pain and discomfort, while eating certain foods. This pain can be incorrectly mistaken for food allergy symptoms. However, the fact is, as the bodies of the victims, suffering from this problem ultimately interpret the foods that they respond to by causing pain, the allergic symptoms follow. The body will react by generating antibodies, which leads to an allergic reaction.
Allergies can be very annoying as they can hamper a normal living routine. Hence, make sure that you interpret your food allergies symptoms clearly and take medical help to get rid of them.

Food Allergies.
True food allergies affect a relatively small percentage of the population. It may be hereditary as it is found to occur most frequently in children with family histories of allergies. The term ‘food allergy’ is sometimes confused for ‘food intolerance’, but they are in fact different. The difference is in the way the body handles the offending food. Here are some facts on food allergies and food intolerance for kids which all mothers should know.
Food allergy, or hypersensitivity, is an abnormal response to a food that is triggered by the immune response. The most commonly affected organ systems and their symptoms include:
• Skin: hives, rashes, eczema
• Mouth: swelling of mouth, tongue
• Digestive tract: nausea, vomiting, diarrhea, abdominal cramps
• Respiratory tract: wheezing, asthma
In contrast, food intolerance is more common and the immune system is not responsible for the symptoms even though the symptoms resemble those of a food allergy. The problem lies with the body’s ability to digest the food, usually due to a chemical deficiency.
For example, difficulty digesting milk (lactose intolerance) due to lactase deficiency. Lactase is the enzyme required to digest milk sugar (lactose), hence deficiency causes abdominal discomfort and diarrhea after taking milk. However, people with food intolerance often can still tolerate some amounts of the offending food without experiencing symptoms.
To reduce the risk of your child developing food allergies, do not introduce solid foods till four months of age unless medically indicated, eg; if your baby has failure to thrive or has iron deficiency anemia. Some may even encourage introducing solids to baby at 6 months. It is prudent that a limited variety and quantity of the least allergenic foods are introduced first in the following progression.
Rice based cereal,
Pureed root vegetables (potatoes, pumpkin, carrots)
Pureed fruits (apple, pear, banana),
Other vegetables (spinach, broccoli),
Meat (pork, beef, lamb).
Only one new food should be introduced at a time and wait a few days before introducing another food. This is to enable identification of the offending food should there be any adverse reactions.
A strawberry allergy is an allergy to certain proteins found in strawberries. When people with an allergy are exposed to these proteins, they develop numbness and tingling in their mouths, along with other symptoms such as burning lips, intestinal distress, and congestion. In some cases, the bronchial tubes may swell and close, causing breathing difficulties and severe health problems. Many people with strawberry allergies also experience contact dermatitis when they touch strawberries or products with strawberry ingredients, which can cause the skin to turn red, puffy, and itchy.
Being allergic to strawberries is fairly common. Most people notice that they have a strawberry allergy because they experience the symptoms after eating or handling strawberries, and the allergy can be confirmed with allergy testing. The only way to manage a strawberry allergy is to avoid eating strawberries and products with strawberry flavoring. This allergy does not extend to other fruits and berries, as it involves a protein unique to strawberries.
Strawberries can turn up in surprising places. Their leaves are sometimes used in herbal teas and certain cosmetics, for example, and strawberry flavoring is used in medications and skin care products. Shampoo and conditioner may have strawberry extract, as can air fresheners and laundry detergent. Avoiding strawberry products can get tricky, but strawberries are usually disclosed on the labeling, as they are an expensive ingredient. People with strawberry allergies are safe around artificial strawberry flavoring, as this product lacks the proteins found in real strawberries.
Studies on strawberries and the blood of people with allergies to these tasty little berries seem to suggest that the protein is similar to that which causes a birch pollen allergy. Someone with a birch pollen allergy can develop a strawberry allergy over time. The red color also appears to play a role, as white strawberry cultivars do not cause allergic reactions. White strawberries are also less flavorful, and researchers are working on making them tastier so that people with strawberry allergies can enjoy these fruits.
In most patients, a strawberry allergy is not life threatening. It can be uncomfortable and irritating, especially when things like strawberry pie are served at parties and the patient must explain that he or she cannot eat the dessert. People with strawberry allergies should try to avoid the berries, however, as a more severe allergic reaction can develop at any time. They should make sure to inform hosts of dinner parties and restaurant staff about their allergy, to confirm that they will not be exposed to strawberry proteins during meals away from home.

Peanut allergies are on the rise worldwide among children.
......and even though awareness is increasing there is still a great risk of exposure for young children and others who suffer. Peanut butter is a universal and cheap source of protein that many families rely on for lunches, making it tough to avoid. Its unlikely that peanut butter and peanuts will disappear so perhaps the best hope for people with peanut allergy symptoms lies in changing the peanut itself.
Researchers are using the protein of the peanut that is responsible for causing allergies to develop immunotherapy programs to combat peanut allergy symptoms.
Another hope is in altering the peanut itself. By identifying which proteins in peanuts are responsible for causing peanut allergy symptoms researchers hope to modify the peanut and eliminate the proteins that are harmful to some. The problem is that there are so many different types of peanuts, the end result might be a peanut that is more of a soy based peanut.
Hopefully researchers will be able to come up with some sort of help as there is currently far to much risk for those who suffer from peanut allergies and even though awareness and education are increasing the peanut is still king of the school lunch. Many product also still contain trace amounts of peanuts and even foods that are produced in the same plant as those that use peanuts can be problematic. A peanut free world does not seem to be possible so science will have to have come up with a solution.

Peanut allergy ,symptoms.Living with a peanut allergy
The peanut problem continues to grow and that’s partially a result of peanuts being a cheap source of dietary protein. At one time it was mainly found in peanut butter but because it is so cheap it is used in many different products. Since there are so many people suffering from a peanut allergy here’s what you need to know.
The problem is as much about it being used in so many products. Rather it is about the labeling and how difficult it is to recognize that there are peanuts in it. Sometimes it is marked as hydrolyzed vegetable protein. Other times as ground nuts. It’s important to understand that a peanut allergy will not go away. In fact as you age it could get worse.
Most of us know about a peanut allergy because it gets so much attention for its seriousness with anaphylactic shock reaction. The peanut allergy can move really quickly and occasionally in just minutes it can prove fatal.
A peanut allergy needs to be treated with epinephrine immediately when the first signs of a reaction. After administering the epinephrine you still must monitor as the reaction can re-occur and another shot will have to be administered.
Possible cof a peanut allergy may include the following which are not listed in any specific order:
1. sense of foreboding, apprehension or fear
2. flushed face, hives, swollen or itchy lips, mouth, eyes, or tongue
3. tightness in chest, throat, or mouth,
4. difficulty breathing or swallowing, wheezing, drooling, coughing, choking, running nose, voice change
5. vomiting, , stomach pains, nausea, diarrhea
6. dizziness, sudden fatigue, rapid heartbeat, unsteadiness, chills
7. loss of consciousness, coma, death
There are many factors which contribute to the peanut allergy being a fatal reaction.
1. Improper Labeling – sadly even though the peanut allergy can be so deadly packaging labeling is still inadequate.
2. Lack of understanding by schools that serve food and restaurants who don’t properly notify customers of a peanut possibility.
3. Nuts marked incorrectly with peanuts being sold as some other type of nut.
4. Failure to carefully read the labels.
5. Failure to inquire at restaurants and places where a problem may arise.
6. Sharing food or utensils that can cross contaminate.
7. Kissing someone that has been eating peanut products.
8. Failure to understand that a very small amount of peanuts can kill.
9. Denial of symptoms that you have a peanut allergy.
10. Not wearing a medical bracelet identifying your allergy.
Thankfully there is a treatment that works well for a serious peanut allergy. But problems still occur which can be fatal. Epinephrine or your Epi-Pen may be outdated. Sometimes a person will wait too long to take their epinephrine. Another problem is not having a second dose of epinephrine with you. Allergy suffers often carry one pen. Another problem is failure to report to emergency after taking epinephrine. All of these issues may be little if the peanut allergy wasn’t so serious.
Living with a peanut allergy is like living with any allergy or illness. The big difference is the seriousness of the peanut allergy. Make sure you understand and make appropriate lifestyle changes.

Environmental issues affecting a person while asleep
We spend so much of our lives sleeping that it only makes sense to consider the impact our sleeping environments have on allergies or MCS. The most frequently advice given to a person with either of these conditions is to avoid the offending substance. As it relates to their sleeping environments, individuals with extreme allergy or chemical sensitivities should evaluate the surface they sleep on. The two primary environmental issues affecting a person while asleep, include:
Dust Mites - People sleeping on mattresses containing dust mites are prime candidates for allergic reactions. However, a non-porous mattress covering will help facilitate sleep for those who are allergic to the common dust mite.
Chemicals - For MCS sufferers, the chemicals contained in and released from mattresses can trigger severe toxic reactions. Mattress foam is treated with fire-retardants, which pose a great health risk.
Mattress foam poses a great health risk because it is treated with fire-retardants. Polybrominated diphenyl ethers (PBDEs), one class of fire-retardants, present the most dangerous health risk of all. PBDEs are similar in makeup to PCBs; they are chemical cousins that have been banned for nearly three decades because they cause immune suppression, endocrine disruption, cancer, behavioral problems and other undesirable effects. In lieu of sleeping on a chemical-free mattress, frequent vacuuming, ventilation at night and running a HEPA air filter will significantly lower the level of exposure of any dangerous chemicals.

Chemical Sensitivities (MCS)
Allergies are hyperactive immune responses that occur when the immune system determines a substance to be a foreign invader. Known as allergens, these potentially harmful substances can range from food to pollen to chemicals to dust. Multiple Chemical Sensitivities (MCS) differs from allergies in that the body cannot defend itself from the neurotoxic chemicals present within our environment. It’s an illness that affects over 16% of the American population.
An allergy is an overactive response by the immune system to various substances that are not harmful in-and-of themselves. As opposed to allergies, chemical sensitivities prevent the body from reacting effectively to potentially harmful chemicals.
Allopathi medicine aims to block or suppress the immune response for allergies, but is frequently seen as only a temporary symptom fix for a systemic weakness. Unfortunately, prescribed medications may cause side effects, as well as progressively weaken the immune system with prolonged use. Just as for allergies, medications may be prescribed to lessen MCS symptoms; however, there is no proven medical treatment to benefit its sufferers. Understanding allergies and MCS from a larger perspective will help in minimizing the impact of these conditions
The Liver’s Role in Allergies
Allergies are often the result of an overloaded toxic state within the liver. As the primary human organ responsible for processing everything we come in contact with, the liver filters out any toxic components introduced into the body. If the quantity of a substance entering the bloodstream is too great for the liver to process quickly, the immune system recognizes the molecules as being an allergen and produces antibodies against them. Through the filtering process, the liver plays a substantial role in reducing the effect an established or potential allergen will have on the body.
The Liver’s Role in MCS
An overexposure to chemicals typically causes Multiple Chemical Sensitivities, which ultimately results in an immune system malfunction. Chemical overexposure damages the liver’s ability to process toxins, rendering the person more susceptible to previously unproblematic chemicals. In addition to chemical overexposure, viruses, severe emotional or physical trauma, liver disease and metabolic disorders are all capable of impairing the liver’s ability to process environmental toxins. Instead of processing chemicals and getting rid of them, the liver’s inability to eliminate toxins facilitates their penetration into every organ system via the blood stream.
Liver Support to Target the Systemic Problem
Many alternative healthcare practitioners are aware of the liver’s role in both allergies and MCS. Many case studies demonstrate that supporting the liver in effectively processing toxins results in reduced allergy and MCS symptoms. Two of the most popular ways to support liver health are:
1. Detoxification - In many cases, a liver detoxification program greatly reduces allergies and MCS. Liver cleansing removes built up sludge responsible for slowing the liver’s processing and filtering duties. Since 1955, many experts in alternative healthcare have relied on the Ayurvedic herbal formula Liv.52 for effective and reliable liver detoxification.
2. Preservation - Preserving the integrity of healthy liver cells assures optimal liver functioning, which reduces allergies and MCS. Milk thistle is one of the most well-known and studied herbs capable of preserving liver cells. Clinical studies have repeatedly demonstrated that milk thistle protects liver cells from damage and helps regenerate new liver cells. The phytosome formula has been shown to be 10 times more bioavailable than standardized milk thistle.

The Most Common Food Allergies In Adults.
The most common food allergies in adults are going to be nuts. There are two kinds of allergies relating to nuts. You will find when asking the question, what is the most common food allergies in adults that peanuts are the upper most on the list. Other allergies that are very common in adults include other nuts or tree nuts, fish, and shellfish. Wheat is another prominent allergy in most adults. You will find that when specifically referring to peanuts there are about 1% of the population who are affected by a peanut allergy and about a .5% allergy to tree nuts.
The most common food allergies in adults are going to offer a variety of degrees in severity as well as the symptoms the adult can suffer. You will find that any person who is allergic to a food can have the severest of reactions, meaning death. Although there are certainly preventative measures, death can be the result if a person doesn't seek medical attention at the first sign of the issue.
For those who have lived with an allergy, even the most common food allergies such as peanuts, they will have an Epi- Pen. The Epi- Pen is filled with epinephrine, which is a common drug used to treat almost any allergy. When the pen is injected into the skin the medication is released immediately into the bloodstream and the individual usually recovers without medical attention. In some cases it will provide enough time to get the person to the emergency room in order to avoid the threat of death.
Basically when discussing what is the most common food allergies in adults, you are going to find that with peanuts the person can have a small reaction like hives, or they can have swelling in the throat, mouth, and stomach pain. Each person is going to be different regarding their reaction to peanuts or other food allergies.
Some individuals don't even realize that they have food allergies until they reach late adulthood when the symptoms become more pronounced. In other cases the adult could have the allergy their entire life, in a severe enough case that they have a special diet, and must avoid most restaurants. You will find that restaurants have taken to warning individuals about peanut products in their menu items to help avoid any issues. The reason of course is that this is the most common food allergy.

Child Allergies
Studies have shown that more than 1 in 5 children suffer from allergies and you child might just be one as well. It's important to understand child allergies and to be aware of the triggering factors within your child.
Allergies are designed to protect us but sometimes our immune systems might take it a little too far and over-react to certain air-borne pollutants and food. When it occurs in young children, especially babies, they can be quite miserable indeed. The symptoms can be anywhere from a simple runny nose, to itchy eyes, stomach aches, rashes and eczema.
With child allergies becoming more and more common these days, we need to learn how to deal with it as part of live. Recent statistics are showing that the number of child allergies are on the rise and "Anaphylaxis", a severe allergic reaction that occurs where the blood pressure drops and breathing becomes quite difficult is increasing as well.
While small children can be allergic to many things, food is by far the most common factor. Foods such as eggs, nuts, soy, wheat and dairy are normally responsible for allergic reaction, especially when ingested for the first time by the child.
The most common signs that your child is allergic to a certain type of food might be the break of our a rash, hives or eczema. Stomach upsets and vomiting is not uncommon either. These symptoms are considered mild and for other more serious reactions like breathing difficulties, call an ambulance right away - do not risk your child's life by thinking that the reaction might subside soon.
Usually it is quite difficult to tell if your child's reaction to a certain food will change as they grow older, but as seen in most cases, if the allergic reaction is mild it will generally remain that way. Overall, most children do outgrow these food allergies by the time they start attending school. However, there are certain allergies like nuts, that people normally never outgrow and become life-long sufferers.
Other allergens such as grass, pet hair, mold and dust mites might cause allergies in children as well. The most common symptoms are runny noses, sneezing and itchy red eyes. Child allergies can also spawn from bee stings or insect bites which can result in a mild rash to the more severe breathing difficulties. Do consult your doctor with regards to what to do should these events occur.
In conclusion, although it is not possible to actually prevent allergies in your children, you can help them by educating them on what the allergic triggers are, so that they know how to avoid allergens when possible.

Important points about Allergies:
Rotate your foods. Avoid eating the same food type/family more than once every four days. Pay close attention to foods that you crave or consume in excessive amounts. Varied and diverse food choices are essential to avoid developing allergies.
Complete a "Spring clean". This will help your body to be less reactive.
Avoid food containing artificial colours and sulphites (food preservatives) to which you are allergic to. These substances cause an overload on the liver.
Organise a comprehensive allergy profile, to detect allergies and 'hidden' or 'delayed' allergies to foods. This speeds up the process of elimination and associated treatment. These tests are available from Ideal Health.
Keep rooms free from dust and wash bedding regularly.
Do not smoke and avoid passive smoking.
Keeping a food diary helps with suspect allergic foods, and your response to these.
Regular exercise is vital for optimum oxygenation of the blood. Good oxygen levels are required for your body to function at its best.

Airborne allergens
Airborne allergens can cause something known as allergic rhinitis, which occurs in about 15% to 20% of Americans. It develops by 10 years of age and reaches its peak in the early twenties, with symptoms often disappearing between the ages of 40 and 60.
Symptoms can include:
sneezing
itchy nose and/or throat
nasal congestion
coughing
These symptoms are often accompanied by itchy, watery, and/or red eyes, which is called allergic conjunctivitis. (When dark circles are present around the eyes, they're called allergic "shiners.") Those who react to airborne allergens usually have allergic rhinitis and/or allergic conjunctivitis. If a person has wheezing and shortness of breath, the allergy may have progressed to become asthma.
Food Allergy Symptoms
The severity of food allergy symptoms and when they develop depends on:
how much of the food is eaten
the person's sensitivity to the food
Symptoms of food allergies can include:
itchy mouth and throat when food is swallowed (some kids have only this symptom — called "oral allergy syndrome")
hives (raised, red, itchy bumps)
eczematous rash
runny, itchy nose
abdominal cramps accompanied by nausea and vomiting or diarrhea (as the body attempts to flush out the food allergen)
difficulty breathing
shock
Insect Venom Allergy Symptoms
Being stung by an insect that a child is allergic to may cause some of these symptoms:
throat swelling
hives over the entire body
difficulty breathing
nausea
diarrhea
shock
About Anaphylaxis
In rare instances, if the sensitivity to an allergen is extreme, a child may experience anaphylaxis (or anaphylactic shock) — a sudden, severe allergic reaction involving various systems in the body (such as the skin, respiratory tract, gastrointestinal tract, and cardiovascular system).
Severe symptoms or reactions to any allergen, from certain foods to insect bites, require immediate medical attention and can include:
difficulty breathing
swelling (particularly of the face, throat, lips, and tongue in cases of food allergies)
rapid drop in blood pressure
dizziness
unconsciousness
hives
tightness of the throat
hoarse voice
lightheadedness
Anaphylaxis can happen just seconds after being exposed to a triggering substance or can be delayed for up to 2 hours if the reaction is from a food. It can involve various areas of the body.
Fortunately, though, severe or life-threatening allergies occur in only a small group of kids. In fact, the annual incidence of anaphylactic reactions is small — about 30 per 100,000 people — although those with asthma, eczema, or hay fever are at greater risk of experiencing them. Most anaphylactic reactions — up to 80% — are caused by peanuts or tree nuts.
Diagnosing Allergies
Some allergies are fairly easy to identify because the pattern of symptoms following exposure to certain allergens can be hard to miss. But other allergies are less obvious because they can masquerade as other conditions.
If your child has cold-like symptoms lasting longer than a week or two or develops a "cold" at the same time every year, consult your doctor, who will likely ask questions about the symptoms and when they appear. Based on the answers to these questions and a physical exam, the doctor may be able to make a diagnosis and prescribe medications or may refer you to an allergist for allergy skin tests and more extensive therapy.
To determine the cause of an allergy, allergists usually perform skin tests for the most common environmental and food allergens. These tests can be done in infants, but they're more reliable in kids over 2 years old.
A skin test can work in one of two ways:
A drop of a purified liquid form of the allergen is dropped onto the skin and the area is pricked with a small pricking device.
A small amount of allergen is injected just under the skin. This test stings a little but isn't extremely painful. After about 15 minutes, if a lump surrounded by a reddish area appears (like a mosquito bite) at the injection site, the test is positive.
If reactions to a food or other allergen are severe, a blood test may be used to diagnose the allergy so as to avoid exposure to the offending allergen. Skin tests are less expensive and more sensitive than blood tests for allergies. But blood tests may be required in children with skin conditions or those who are extremely sensitive to a particular allergen.
Even if a skin test and/or a blood test shows an allergy, a child must also have symptoms to be definitively diagnosed with an allergy. For example, a toddler who has a positive test for dust mites and sneezes frequently while playing on the floor would be considered allergic to dust mites.
Treating Allergies
There is no real cure for allergies, but it is possible to relieve symptoms. The only real way to cope with them is to reduce or eliminate exposure to allergens. That means that parents must educate their kids early and often, not only about the allergy itself, but also about what reaction they will have if they consume or come into contact with the allergen.
Informing any and all caregivers (childcare personnel, teachers, extended family members, parents of your child's friends, etc.) about your child's allergy is equally important.
If reducing exposure isn't possible or is ineffective, medications may be prescribed, including antihistamines (which you can also buy over the counter) and inhaled or nasal spray steroids.
In some cases, an allergist may recommend immunotherapy (allergy shots) to help desensitize your child. However, allergy shots are only helpful for allergens such as dust, mold, pollens, animals, and insect stings. They're not used for food allergies, and someone with food allergies must avoid that food.
Here are some things that can help kids avoid airborne allergens:
Keep family pets out of certain rooms, like your child's bedroom, and bathe them if necessary.
Remove carpets or rugs from your child's room (hard floor surfaces don't collect dust as much as carpets do).
Don't hang heavy drapes and get rid of other items that allow dust to accumulate.
Clean frequently.
Use special covers to seal pillows and mattresses if your child is allergic to dust mites.
For kids allergic to pollen, keep the windows closed when the pollen season is at its peak, change their clothing after they've been outdoors, and don't let them mow the lawn.
Keep kids who are allergic to mold away from damp areas, such as basements, and keep bathrooms and other mold-prone areas clean and dry.
Injectable Epinephrine
Food allergies usually aren't lifelong (although those to peanuts, tree nuts, and seafood can be). Avoiding the food is the only way to avoid symptoms while the sensitivity persists.
Doctors often recommend that caregivers of kids who are extremely sensitive to a particular food, have asthma in addition to the food allergy, or are allergic to insect venom carry injectable epinephrine (adrenaline) to counteract any allergic reactions.
Available in an easy-to-carry container that looks like a pen, injectable epinephrine is carried by millions of parents (and older kids) everywhere they go. With one injection into the thigh, the device administers epinephrine to ease the allergic reaction.
An injectable epinephrine prescription usually includes two auto-injectors and a "trainer" that contains no needle or epinephrine, but allows you and your child (if he or she is old enough) to practice using the device. It's vital that you familiarize yourself with the procedure by practicing with the trainer. Your doctor also can provide instructions on how to use and store injectable epinephrine.
Make sure kids 12 years or older keep injectable epinephrine readily available at all times. If your child is younger than 12, talk to the school nurse, teachers, and your childcare provider about keeping injectable epinephrine on hand in case of an emergency.
It's also important to ensure that injectable epinephrine devices are available in your home and in the homes of friends and family members if your child spends time there. Your doctor may also encourage your child to wear a medical alert bracelet. It's also wise to carry an over-the-counter antihistamine, which can help alleviate allergy symptoms in some people. But antihistamines should not be used as a replacement for the epinephrine pen.
Kids who have had to take injectable epinephrine should go immediately to a medical facility or hospital emergency department, where additional treatment can be given if needed. Up to one third of anaphylactic reactions can have a second wave of symptoms several hours following the initial attack, so these kids might need to be observed in a clinic or hospital for 4 to 8 hours following the reaction even though they seem well.
The good news is that only a very small group of kids will experience severe or life-threatening allergies. With proper diagnosis, preventive measures, and treatment, most kids can keep their allergies in check and live happy, healthy lives.

Allergic Reaction Overview
An allergic reaction is the body's way of responding to an "invader." When the body senses a foreign substance, called an antigen, the immune system is triggered. The immune system normally protects the body from harmful agents such as bacteria and toxins. Its overreaction to a harmless substance (an allergen) is called a hypersensitivity reaction, or an allergic, reaction.
•Anything can be an allergen. Common dust, pollen, plants, medications, certain foods, insect venoms, animal dander, viruses, or bacteria are examples of allergens.
•Reactions may occur in one spot, such as a small skin rash or itchy eyes, or all over, as in a whole body rash.
•A reaction may include one or several symptoms.
In rare cases, an allergic reaction can be life-threatening (known as anaphylaxis). Each year in the United States, over 400 people die from anaphylactic reactions to penicillin, and nearly 100 Americans die from anaphylactic reactions to insects, according to the Asthma and Allergy Foundation of America (AAFA).
Most allergic reactions are much less serious, such as a rash from poison ivy or sneezing from hay fever. The type of reaction depends on the person but is sometimes unpredictable.
Allergies are very common. The AAFA states allergies account for more than 17 million visits to the doctor each year. More than half of all allergy visits are for seasonal allergies. More than 7 million people visit their doctor for skin allergies annually, and food allergies account for 30,000 visits to the emergency room.

Allergic Shock/Anaphylaxis
Allergic shock (anaphylaxis or anaphylactic shock) is a life-threatening allergic reaction that can affect a number of organs at the same time. This response typically occurs when the allergen is eaten (for example, foods) or injected (for example, a bee sting). Some or all of the following symptoms may occur:
Hives or reddish discoloration of the skin
Nasal congestion
Swelling of the throat
Stomach pain, nausea, vomiting
Shortness of breath, wheezing
Low blood pressure or shock
Shock refers to the insufficient circulation of blood to the body's tissues. Shock is most commonly caused by blood loss or an infection. Allergic shock is caused by dilated and "leaky" blood vessels, which result in a drop in blood pressure.
What is anaphylaxis?
Anaphylaxis or anaphylactic shock is a rare but serious condition, it is the end result of a severe allergic reaction. The reaction affects the whole body, causing a sudden drop in blood pressure and narrowing of the airways.
What causes anaphylaxis?
Anaphylaxis is caused by an extreme sensitivity to an allergen. The most common allergens which cause anaphylaxis are peanuts, tree nuts, bee/wasp stings or a drug, such as the antibiotic penicillin. For more information on food allergies click here.
It is unknown why some people get anaphylaxis and others don't, however, it usually happens to people who are known to have allergies.
How do I know if I'm at risk of anaphylaxis?
If you have previously suffered from a bad allergic reaction, then a future reaction may also be severe. If you ever experience any allergy symptoms (especially after eating nuts), no matter how mild, then this should be regarded as a possible warning sign of a more severe allergic reaction and you should seek your doctors advice. Allergic reactions are unpredictable and can vary in severity from one time to the next.
What are the symptoms of anaphylaxis?
The symptoms of anaphylaxis normally begin within minutes of exposure or contact to the allergen and can be quite rapid, though in some situations this process can take hours. Symptoms of anaphylaxis could include any of the following:
Swelling and itching in the mouth and throat
A rash, anywhere on the body and the skin may appear flushed.
Difficulty in swallowing or speaking.
Difficulty breathing
Abdominal cramps
Nausea and vomiting.
Feeling of 'impending doom'.
A drop in blood pressure, which makes the person feel weak
Collapse and unconsciousness.
You may not necessarily experience all of the symptoms above and some people may only ever have mild symptoms, for example they may just notice a tingling or itching in the mouth. This can be treated with oral antihistamines. However, you should still seek your doctors advice because next time the reaction could be more severe.
Can anaphylaxis be diagnosed?
There are tests available to diagnose what specific allergens you are allergic to but as yet there is no perfect way of measuring an individual's potential for a severe allergic reaction. For more information on allergy tests read the section "How are allergies diagnosed?" on the allergies page.
What is the treatment for anaphylaxis?
The best treatment for anaphylaxis is avoiding the allergen to which you are allergic, especially if you have had a previous serious reaction. Please read the individual subjects on food allergies and insect bites for more tips on avoiding specific allergens.
It is important that if a person is suffering with anaphylaxis that they get immediate treatment with adrenaline (also named epinephrine) the minute a serious reaction is suspected. The adrenaline injection will raise the blood pressure, stimulate the heartbeat, relieve breathing difficulties and reduce swelling. In order for the treatment to be effective it must be administered very quickly. If you have had a previous serious reaction or your doctor suspects you are at risk of one, then you should be given a pre-loaded adrenaline injection to carry. You must ensure that you always have the adrenaline kit with you and make sure you are comfortable using the one that has been prescribed to you. If you are unsure speak to your doctor for advice or ask for a different kind.
Adrenaline treatments you could be given may include the following:
Medihaler-Epi - if the symptoms include swelling of the mouth a treatment called a Medihaler-Epi should be used. A Medihaler-Epi is an aerosol containing adrenaline, the requirement is usually 4 puffs sprayed into the mouth. This type of treatment is not suitable for widespread allergic reactions.
Epipens - the treatment of severe allergic reactions to foods has been revolutionised by the introduction of the Epipen auto-injector. This device has a spring-activated needle and is designed to deliver a single 0.3mg dose of adrenaline into your muscle when the pen is pushed into your skin.
Min-i-jets - the Min-i-jet works in the same way as the Epipen but consists of a 1ml disposable syringe and needle. The dose will need to be measured accurately, as a full syringe will deliver 1mg of adrenaline.
The majority of food allergy sufferers prefer the use of the Epipen due to the ease and the simplicity. There is no visible needle and the device has a shelf-life of 2 years compared to 9 months for the Mini-i-jet. In some cases a single dose of the Epipen may not prove enough to treat severe reactions, you should always carry two Epipens as a safety measure. If you are at risk from severe allergic reactions then you must carry medications around at all times.
If you have suffered this kind of severe allergic reaction you should still go to a hospital for observation, or call an ambulance.
Your doctor should also give you an emergency card or bracelet, which you should always carry to alert others to your allergy. You should also inform those around you at work and home of your allergy. Show them where you keep your medicine and how to use it in case of an emergency. Make sure your medicine is always in easy access and that the expiry date has not passed.
If you believe you or someone else is having this severe reaction you should first try and administer adrenaline. Don't kid yourself of the symptoms, if you think you are beginning to show the signs of a severe reaction, reach for the adrenaline injection. If there is none available then call an ambulance or if closer get to a hospital or GP's clinic as soon as you can.
Information on Allergies
An allergy refers to an exaggerated reaction by our immune system in response to bodily contact with certain foreign substances. It is exaggerated because these foreign substances are usually seen by the body as harmless and no response occurs in nonallergic people. Allergic people's bodies recognize the foreign substance and one part of the immune system is turned on. Allergy-producing substances are called "allergens." Examples of allergens include pollens, dust mite, molds, danders, and foods. To understand the language of allergy it is important to remember that allergens are substances that are foreign to the body and can cause an allergic reaction in certain people.
When an allergen comes in contact with the body, it causes the immune system to develop an allergic reaction in persons who are allergic to it. When you inappropriately react to allergens that are normally harmless to other people, you are having an allergic reaction and can be referred to as allergic or atopic. Therefore, people who are prone to allergies are said to be allergic or "atopic."
Austrian pediatrician Clemens Pirquet (1874-1929) first used the term allergy. He referred to both immunity that was beneficial and to the harmful hypersensitivity as "allergy." The word allergy is derived from the Greek words "allos," meaning different or changed and "ergos," meaning work or action. Allergy roughly refers to an "altered reaction." The word allergy was first used in 1905 to describe the adverse reactions of children who were given repeated shots of horse serum to fight infection. The following year, the term allergy was proposed to explain this unexpected "changed reactivity."
