Allergic Food Reaction |
Details
|
An allergic reaction to food happens when a body’s immune system identifies a protein or a related substance in the offending food as the enemy and sends out a battalion of defenses to destroy it. In this case an immune system called histamines produces painful sensations in the eyes, skin, and throat. The entry of an allergen (any substance that causes an allergic reaction), into the body of a susceptible individual triggers a chain of events in the immune system. In one type, antibodies are created after one exposure to food in order to fight the “invaders” next time. These antibodies are known as immunoglobulin and are usually identified by a blood test. In another type of reaction, immune cells called Lymphocytes become sensitized over time by exposure to some chemicals and protein in food. When they meet next, the lymphocytes overreact, expelling the foreign material just as they would reject an organ transplant. The effects of exposure to a food allergen range from a little tingling in the mouth to swelling and redness of the skin to life-threatening problems. Symptoms of allergy may include vomiting, difficulty breathing, hives, and diarrhea. People with such symptoms need to contact a doctor. Allergic reactions as described above are usually treated with antihistamines.
