What is the treatment for food allergies

Allergic symptoms generally start within minutes of eating the food, but can take up to 2 hours to progress. Since the symptoms of a food allergy may mimic other medical conditions or problems, always consult yourdoctor for a diagnosis. Common symptoms are listed below:

  1. Trouble breathing or wheezing
  2. Swelling, itching of lips and mouth
  3. Vomiting
  4. Hives, or itchy, raised bumps
  5. Low blood pressure
  6. Tightness in the throat or hoarse voice
  7. Flushing or swelling of the skin
  8. Feeling faint or losing consciousness
  9. Heart palpitations
  10. Anxiety with an impending sense of doom

Anaphylaxis or allergic shock is a medical emergency treated with epinephrine. Call 911 for immediate medical assistance.

Those with known food allergies should carry emergency kits with epinephrine auto-injectors.


What is the difference between food allergy and food intolerance?

Food allergies are caused by the immune system. Food intolerances refer to non-immune mediated adverse reactions to foods. One example of food intolerance is lactose intolerance, a metabolic deficiency of an enzyme required to metabolize lactose. Another example of food intolerance is scromboid poisoning which is a reaction that can mimic an allergic reaction but is triggered by a toxin (not IgE mediated) found in seafood.

It is crucial to distinguish between food allergy and food intolerance because in general, a food intolerance does not increase risk of progression to anaphylaxis (potentially severe life threatening allergic reaction).


Food Allergies


Which foods most often cause food allergies?

  1. Wheat
  2. About 90% of every food allergies are caused by 9 foods:
  3. Soy
  4. Peanut
  5. Sesame
  6. Cow’s Milk
  7. Tree Nuts (Almond, Walnuts, Cashews, etc.)
  8. Chicken eggs
  9. Fish
  10. Shellfish
  11. Eggs, milk, and peanuts are the most common causes of food allergies in children.

    Peanuts, tree nuts, fish, and shellfish commonly cause the most severe reactions.


If your kid has symptoms after eating certain foods, he or she may own a food allergy.

A food allergy occurs when the body’s immune system sees a certain food as harmful and reacts by causing symptoms. This is an allergic reaction. Foods that cause allergic reactions are allergens.

IgE Mediated Food Allergies

The IgE mediated food allergies most common in infants and children are eggs, milk, peanuts, tree nuts, soy and wheat. The allergic reaction can involve the skin, mouth, eyes, lungs, heart, gut and brain.

Some of the symptoms can include:

  1. Stomach pain, vomiting, diarrhea
  2. Skin rash, itching, hives
  3. Feeling love something terrible is about to happen
  4. Swelling of the lips, tongue or throat
  5. Immunoglobulin E (IgE) mediated. Symptoms result from the body’s immune system making antibodies called Immunoglobulin E (IgE) antibodies. These IgE antibodies react with a certain food.
  6. Shortness of breath, trouble breathing, wheezing
  7. Non-IgE mediated. Other parts of the body’s immune system react to a certain food. This reaction causes symptoms, but does not involve an IgE antibody. Someone can own both IgE mediated and non-IgE mediated food allergies.

Sometimes allergy symptoms are mild.

Other times they can be severe. Take every allergic symptoms seriously. Mild and severe symptoms can lead to a serious allergic reaction called anaphylaxis (anna-fih-LACK-sis). This reaction generally involves more than one part of the body and can get worse quick. Anaphylaxis must be treated correct away to provide the best chance for improvement and prevent serious, potentially life-threatening complications.

Treat anaphylaxis with epinephrine. This medicine is safe and comes in an easy-to-use device called an auto-injector. You can’t rely on antihistamines to treat anaphylaxis.

The symptoms of an anaphylactic reaction happen shortly after contact with an allergen. In some individuals, there may be a delay of two to three hours before symptoms first appear.

Cross-Reactivity and Oral Allergy Syndrome

Having an IgE mediated allergy to one food can mean your kid is allergic to similar foods. For example, if your kid is allergic to shrimp, he or she may be allergic to other types of shellfish, such as crab or crayfish. Or if your kid is allergic to cow’s milk, he or she may also be allergic to goat’s and sheep’s milk. The reaction between diverse foods is called cross-reactivity.

This happens when proteins in one food are similar to the proteins in another food.

Cross-reactivity also can happen between latex and certain foods. For example, a kid who has an allergy to latex may also own an allergy to bananas, avocados, kiwis or chestnuts.

Some people who own allergies to pollens, such as ragweed and grasses, may also be allergic to some foods. Proteins in the pollens are love the proteins in some fruits and vegetables. So, if your kid is allergic to ragweed, he or she may own an allergic reaction to melons and bananas.

That’s because the protein in ragweed looks love the proteins in melons and bananas. This condition is oral allergy syndrome.

Symptoms of an oral allergy syndrome include an itchy mouth, throat or tongue. Symptoms can be more severe and may include hives, shortness of breath and vomiting. Reactions generally happen only when someone eats raw food. In rare cases, reactions can be life-threatening and need epinephrine.

Two Categories of Food Allergies

  • Immunoglobulin E (IgE) mediated.

    What is the treatment for food allergies

    Symptoms result from the body’s immune system making antibodies called Immunoglobulin E (IgE) antibodies. These IgE antibodies react with a certain food.

  • Non-IgE mediated. Other parts of the body’s immune system react to a certain food. This reaction causes symptoms, but does not involve an IgE antibody. Someone can own both IgE mediated and non-IgE mediated food allergies.

Non-IgE Mediated Food Allergies

Most symptoms of non-IgE mediated food allergies involve the digestive tract.

Symptoms may be vomiting and diarrhea. The symptoms can take longer to develop and may final longer than IgE mediated allergy symptoms. Sometimes, a reaction to a food allergen occurs up 3 days after eating the food allergen.

When an allergic reaction occurs with this type of allergy, epinephrine is generally not needed. In general, the best way to treat these allergies is to stay away from the food that causes the reaction. Under are examples of conditions related to non-IgE mediated food allergies.

Not every children who react to a certain food own an allergy.

They may own food intolerance. Examples are lactose intolerance, gluten intolerance, sulfite sensitivity or dye sensitivity. Staying away from these foods is the best way to avoid a reaction. Your child’s doctor may propose other steps to prevent a reaction. If your kid has any food allergy symptoms, see your child’s doctor or allergist. Only a doctor can properly diagnose whether your kid has an IgE- or non-IgE food allergy. Both can be present in some children.

Eosinophilic Esophagitis (EoE)

Eosinophilic (ee-uh-sin-uh-fil-ik) esophagitis is an inflamed esophagus.

The esophagus is a tube from the throat to the stomach.

What is the treatment for food allergies

An allergy to a food can cause this condition.

With EoE, swallowing food can be hard and painful. Symptoms in infants and toddlers are irritability, problems with eating and poor weight acquire. Older children may own reflux, vomiting, stomach pain, chest pain and a feeling love food is “stuck” in their throat. The symptoms can happen days or even weeks after eating a food allergen.

EoE is treated by special diets that remove the foods that are causing the condition. Medication may also be used to reduce inflammation.

Food Protein-Induced Enterocolitis Syndrome (FPIES)

FPIES is another type of food allergy.

It most often affects young infants. Symptoms generally don’t appear for two or more hours. Symptoms include vomiting, which starts about 2 hours or later after eating the food causing the condition. This condition can also cause diarrhea and failure to acquire weight or height. Once the baby stops eating the food causing the allergy, the symptoms go away. Rarely, severe vomiting and diarrhea can happen which can lead to dehydration and even shock.

Shock occurs when the body is not getting enough blood flow. Emergency treatment for severe symptoms must happen correct away at a hospital. The foods most likely to cause a reaction are dairy, soy, rice, oat, barley, green beans, peas, sweet potatoes, squash and poultry.

Allergic Proctocolitis

Allergic proctocolitis is an allergy to formula or breast milk.

What is the treatment for food allergies

This condition inflames the lower part of the intestine. It affects infants in their first year of life and generally ends by age 1 year.

The symptoms include blood-streaked, watery and mucus-filled stools. Infants may also develop green stools, diarrhea, vomiting, anemia (low blood count) and fussiness. When properly diagnosed, symptoms resolve once the offending food(s) are removed from the diet.

What is a food allergy?

A food allergy is an abnormal reproducible response of the body’s immune system tocertain aspects of specific foods that cause potentially dangerous allergic reactions.


What causes food allergies?

Food allergies are most commonly caused by allergic antibodies (IgE) to the problem food(s), but may result from other specialized immune pathways (non IgE mediated or mixed IgE and non-IgE mediated) such as eosinophilic esophagitis, celiac, atopic dermatitis or food protein enterocolitis (FPIES).

Interactions between the problem food and allergic antibodies (IgE) cause an allergic reaction by the release of histamine and other inflammatory chemicals which cause the symptoms, of varying degrees, typically seen in an allergic reaction — hives, swelling, itching in the mouth, throat irritation, trouble breathing, vomiting, fainting, anaphylaxis.
