Being allergic to certain foods can make dining out challenging, so it is wise to carry emergency epinephrine autoinjectors such as Adrenaclick or EpiPen for quick administration in case of severe reactions.
Most children outgrow food allergies during childhood. Unfortunately, however, peanut, egg, milk, wheat, soy, fish crustacean shellfish and sesame allergies still pose serious challenges to many adults today.
Symptoms
Allergies arise when your immune system mistakenly misidentifies specific foods as harmful, like viruses or bacteria, and releases antibodies in response. As these antibodies attack and fight off these offending items, their release leads to symptoms ranging from mild to severe reactions of food allergies; common food allergens include milk, eggs, wheat, soy and peanuts – and sometimes fish, shellfish and even oral allergy syndrome as well. Children typically outgrow reactions related to milk and eggs but allergies to peanuts/tree nuts/fish/shellfish tend to persist into adulthood while reactions related to milk/eggs/etc usually outgrow reactions related to milk/eggs allergies while allergies to peanuts/tree nuts/fish/shellfish may remain lifelong reactions due to oral allergy syndrome affecting them as children grow older – but tend not so with respect to milk/egg allergies/etc being lifelong as opposed to milk/egg allergies which often outgrow reactions associated with these allergies eventually outgrowing reactions related to milk/egg allergies outgrow; however these allergies tend to remain lifelong (unless affected).
Food allergies can affect any part of the body and may appear either shortly after eating the offending food or several hours later. Common symptoms can include hives, swelling, difficulty breathing and difficulty swallowing. Anaphylaxis is a medical emergency requiring immediate treatment with injectable epinephrine.
Your healthcare provider can diagnose food allergies by reviewing symptoms and when they began, as well as conducting a physical exam and gathering medical history information from you and your child. He or she may order an allergy skin test or blood test; in an allergy skin test, liquid extracts of suspected allergens are applied directly onto forearm or back skin and pricked several times; reddish raised spots known as wheals appear if an allergic reaction to that food occurs.
Diagnosis
Symptoms of food allergy in your child should prompt a visit to their physician. A comprehensive history, elimination diet and skin and blood tests could all be important tools in diagnosing their allergy.
People with food allergies typically possess an immune system which mistakes proteins found in certain foods as harmful, leading their bodies to produce immunoglobulin E (IgE) antibodies in response. When exposed to their allergen, these IgE antibodies bind with its proteins and trigger an allergic response; symptoms may include hives, itching in the mouth or throat, belly pain and trouble breathing as well as sudden drops in blood pressure (anaphylactic shock).
Food allergies typically surface during early childhood. While some disappear by early adulthood, others remain. Your physician can perform skin prick tests and blood tests to check for antibodies against food allergens that could indicate whether or not you have one.
Your child should discontinue taking medicines that affect his/her symptoms (such as over-the-counter antihistamines) 5 to 7 days prior to having a skin test unless advised otherwise by their physician. Your physician might conduct an oral food challenge test in which increasing amounts of the allergen are eaten while watching for any signs of reaction; this test must take place in an environment with immediate emergency care and medicines available, since an adverse reaction could prove deadly.
Treatment
Food allergies can be treated by avoiding foods that trigger them. This may be difficult for children and parents alike. A dietitian or nutritionist can assist in finding ways to ensure you still receive essential nutrition without certain foods, while support groups, both in person and online, may also prove invaluable.
If your food allergy symptoms are severe, carrying an adrenalin click (EpiPen) at all times is essential to managing them quickly and safely. Your physician will instruct you how to use one.
Allergy skin tests and blood tests can help identify which foods are more likely to trigger reactions. Pricking the skin with small amounts of the allergen to see if there is an immediate reaction, while blood tests measure antibodies specific to allergens.
Some individuals may require additional advanced testing, including oral food challenges or placebo challenges. During these exams, you are gradually given increasing amounts of the food suspected to be the cause of their symptoms; if no adverse reaction occurs then adding it back into their diet should be safe.
Thousands of people with food allergies are seeing improved symptoms thanks to breakthrough treatments that go beyond mere avoidance. Oral immunotherapy (OIT) and sublingual immunotherapy (SLIT) may provide relief if simply avoiding allergens is ineffective; epicutaneous immunotherapy – where an allergy patch containing allergens is worn on the skin for an extended period – offers hope to those unable to avoid certain foods entirely. Although these therapies remain experimental, they provide hope for those unable to completely avoid allergenic food sources.
Prevention
Some individuals with food allergies can prevent an adverse reaction by simply avoiding certain foods, while epinephrine auto-injectors (such as Adrenaclick or EpiPen) can provide emergency assistance in cases of potentially life-threatening allergic reactions.
Communicate with your health care team regarding how to avoid foods you are allergic to. Most individuals with food allergies should carry medication at all times in case someone doesn’t understand about their allergy.
Food allergies often appear within minutes after eating an allergen and can have serious repercussions for various body systems, including respiratory, gastrointestinal, cardiovascular, nervous, and dermatology systems. Severe allergic reactions include wheezing, hives, swelling of mouth or throat area and difficulty breathing due to constricted airways – even shock due to sudden drop in blood pressure can occur as severe allergic reactions progress rapidly.
Food allergy prevention strategies include eliminating potentially allergenic foods during gestation and early infancy diet, waiting to introduce allergy-provoking food such as peanuts until approximately 6 months old, etc.
Taught children with food allergies the importance of reading labels and avoiding foods they are allergic to is crucial in managing their allergies effectively. They should practice being assertive when refusing foods they shouldn’t eat and seeking help when feeling an adverse reaction coming on. In addition, get them used to carrying an auto-injector (epinephrine auto-injector).
