Food allergies in general usually have a fast onset (from seconds to one hour). Symptoms may include rash, hives, itching of mouth, lips, tongue, throat, eyes, skin, or other areas, swelling of lips, tongue, eyelids, or the whole face, difficulty swallowing, runny or congested nose, hoarse voice, wheezing, shortness of breath, diarrhea, abdominal pain, lightheadedness, fainting, nausea, or vomiting. Symptoms of allergies vary from person to person and incident to incident. Potentially a life-threatening response, the onset of an allergic reaction occurs when respiratory distress occurs, indicated by wheezing, breathing difficulty, and cyanosis, and circulatory impairment exhibits with a weak pulse, pale skin, and fainting. Such a severe allergic reaction is called anaphylaxis when IgE antibodies are released, and areas of the body not in direct contact with the food show severe symptoms. Untreated, the overall response can proceed to vasodilation, a low blood pressure situation called anaphylactic shock. All of these symptoms have been mentioned in descriptions of<unk> .
