Signs and symptoms of food allergy include an itching feeling in the mouth, tingling lips, swollen lips, swelling in the tongue and throat, difficulty swallowing, and problems with breathing. When the allergens (the substances that provoke an allergic reaction) are digested or absorbed in the bloodstream, other associated symptoms can result. These can include asthma with wheezing, hives, rash, eczema, nausea, diarrhea, abdominal pain, or vomiting.
Cause of food allergies
Both genetic and environmental factors may cause a food allergy. Food allergies involve the activation of the immune system as in other allergic reactions.
