Food allergies cannot be cured, but they can be managed through a combination of avoiding the allergen, medication, and in some cases, immunotherapy (allergy shots).
A food allergy is an immune system reaction to a food protein that the body mistakenly believes is harmful. The immune system produces antibodies to fight the allergen, which results in the release of chemicals such as histamine, causing symptoms like hives, itching, difficulty breathing and in some cases, anaphylaxis, a life-threatening condition.
The best way to manage a food allergy is to avoid the allergen completely. This can be done by reading food labels carefully, being aware of cross-contamination and asking about ingredients when eating out. Medications such as antihistamines and epinephrine (an injection to counteract an anaphylactic reaction) can be used to treat symptoms, but they do not cure the allergy.
Allergen immunotherapy, also called desensitization or hyposensitization, is a form of treatment that involves exposing the person to small amounts of the allergen in order to build up tolerance over time. This treatment is usually administered under the guidance of an allergist and is considered only for certain types of allergies and patients with moderate to severe symptoms.
It's important to note that it's not possible to predict whether an allergy will persist or resolve over time. Consult with a specialist in Allergology who can help you to manage your food allergies and plan to prevent severe reactions.
