Food allergies are severe reactions to certain foods that can have serious adverse reactions on our bodies, including drops in blood pressure, difficulty breathing and even hives.
Food allergies often arise due to milk, eggs, wheat, soy or peanuts; those suffering must read labels carefully and avoid these items when possible. Furthermore, it’s essential that others know of your allergy as well as keep emergency medication on hand (like an EpiPen).
Symptoms
Food allergies are reactions your body has against food that it misperceives as dangerous, which lead to immunoglobulin E (IgE) antibodies being produced and released when you eat an allergenic food, often manifesting with symptoms like hives or itchy mouth/throat; for more severe cases – anaphylaxis can occur and must be treated immediately using injectable epinephrine injection.
Food allergies usually begin within two hours after consuming an offending food and may affect multiple parts of your body, from mild to severe reactions that affect different areas. Most symptoms affect multiple areas simultaneously and tend to be milder in children than adults.
Untreated allergy symptoms may result in life-threatening anaphylaxis reactions that make breathing difficult or impossible, making an emergency plan essential. Carrying an epinephrine auto-injector such as Adrenaclick or EpiPen and knowing what steps should be taken during an extreme reaction are two good strategies for responding swiftly.
Your doctor can diagnose food allergies through taking a comprehensive history, performing skin and blood tests, or sending you to an allergist for skin prick testing with food extracts. They may also suggest an elimination diet and meal planning assistance.
Diagnosis
Your health care provider can identify food allergies through an in-depth history review, skin and blood tests, as well as an oral food challenge. Skin testing involves pricking the skin with small amounts of the suspected allergenic food; if someone is allergic to that food, an itchy bump known as a hive will appear under their skin. Blood tests also exist to detect IgE antibodies against specific foods in their bloodstream – these tests can be obtained widely and do not need to be conducted by an allergist.
Food allergies typically manifest within two hours after ingesting offending foods, though sometimes symptoms can take up to 48 hours before showing. They can vary from mild to severe symptoms that include tingling in the mouth or throat to swelling lips, face tongue or throat and itchy throat or belly as well as wheezing trouble breathing constriction or tightening of airways swollen neck or drop blood pressure (anaphylaxis).
If you experience food allergy symptoms, especially if accompanied by asthma or eczema, seeing an allergist is of vital importance. Your physician can provide an emergency kit containing epinephrine that must be kept with you at all times in case of an extreme reaction and show how to use it effectively. In addition, they will educate family members, babysitters and school staff members regarding food allergies so they can help to prevent reactions.
Treatment
Food allergies are a growing public health threat that can be life-threatening, with reactions ranging from mild to severe and impacting any part of the body. The only effective way to avoid an adverse reaction is avoiding what triggers it; oral immunotherapy (OIT), however, offers another potential treatment option to desensitize immunity over time and make an individual less reactive to certain food allergens over time. OIT treatment options are available both to children and adults diagnosed with food allergies; treatment should always be carried out under medical supervision.
Food allergy skin tests and blood tests can help identify foods causing your symptoms. If you suspect a potential delay in symptoms after eating a particular food, your doctor may test for delayed-type hypersensitivity syndrome (EDHS), similar to allergic reactions but which often happens two to six hours post-ingestion and causes symptoms like hives, swelling and an upset stomach.
Medication may help ease symptoms associated with food allergy reactions, such as antihistamines that block histamine release to decrease itching and rashes and bronchodilators that help breathing. Your doctor may also advise carrying an auto-injector such as EpiPen or Auvi-Q with you in case of severe reactions that could save your life; to minimize severity follow an elimination diet while carefully reading ingredient labels.
Prevention
Food allergies occur when your immune system mistakesnly recognizes a food or food component as potentially harmful, prompting it to produce antibodies known as immunoglobulin E (IgE) to attack it. When you eat again any amount of this allergenic food, IgE antibodies recognize it and release chemicals into your bloodstream that cause skin rashes, breathing issues or digestive discomfort (GI) symptoms – symptoms which could potentially include skin rashes or digestive distress (GI).
Food allergies have no known cure, but strict avoidance can reduce symptoms. Be sure to carefully read food labels and look out for potential allergens such as milk, eggs, fish, wheat, peanuts, soy tree nuts or crustacean shellfish as these could trigger reactions in sensitive individuals. If you need assistance finding particular items try speaking to a dietitian or nutritionist specialized in working with those suffering from food allergies for advice and support.
At times, doctors may suggest an oral food challenge to help identify whether you have food allergies. This must only be conducted under the supervision of an experienced allergist at a clinic with proper equipment and emergency medication on hand. Always carry an epinephrine auto-injector (also called adrenaline injector) as severe allergic reactions known as anaphylaxis may become life threatening in an instantaneous situation. Also be sure that all schools or childcare services where your children will eat have written anaphylaxis management policies as well as trained personnel using an adrenaline auto-injector (also called adrenaline injector).
