Skin Allergies By Food: Symptoms Causes And Treatment

A food allergy is an adverse immune-mediated reaction to a specific food. Even a small amount of a particular food can cause skin rash, nausea, vomiting, cramping, and diarrhoea in someone with a food allergy. This allergic reaction is often referred to as hypersensitivity because the body reacts to something harmless. Anaphylaxis, or anaphylactic shock, is a potentially fatal reaction to a severe allergic reaction.
