    Suffering From Food allergy? Know What It Is.

    Food allergy is a kind of immune response that occurs after eating a certain food. Even a tiny amount of the allergen in the food can trigger symptoms such as digestive problems, hives or swollen lips, etc. When our immune system mistakenly thinks of food as a foreign invader, it triggers an immune response resulting in the release of chemicals from the body as a part of defense mechanism, causing symptoms (hypersensitivity reaction). In severe cases, food allergy can cause life-threatening anaphylaxis.

    Data reveals:


    Statistics-wise, food allergy affects 6 to 8 percent of children under age 3 and 3 percent of adults. There is no proven cure as such, some children outgrow their food allergy as they get older.

    Foods that cause hypersensitivity reactions in people are known as food allergens. These include certain foods such as eggs, milk, peanuts, fish, and shellfish, and it is known that seafood allergy is one of the most common food allergies in adults and children as it constitutes a major part of Asians’ diets. Food allergic reactions vary in severity from mild – involving hives and lip swelling to severe – life-threatening anaphylaxis that leads to fatal respiratory problems

    Anaphylaxis is a type of severe allergic reaction which is potentially life-threatening. It can impair your breathing and send the body into a stage of shock. It happens soon after being exposed to the specific food allergen but sometimes it takes a few hours to arise.

    The symptoms usually come on quickly and might worsen rapidly such as:

    • Nausea and vomiting
    • loss of consciousness
    • sneezing
    • respiratory problems, shortness of breath, which often become worse
    • streaming nose
    • rapid swelling of the throat, lips, face, and mouth
    • a fast heartbeat
