Anaphylaxis is a generalized allergic reaction that is often severe and sometimes fat al. This reaction may involve any body system. However, the stomach, skin, nose, throat, larynx, lungs, intestinal tract, heart, and blood pressure are primarily affected.
The earliest signs of a serious allergic reaction may be a red, itchy rash and a feeling of warmth. This may be accompanied by lightheadedness, difficulty in breathing, fainting, abdominal pain, and nausea or vomiting.
Foods that frequently cause anaphylaxis include peanuts, nuts, shellfish, eggs, and seeds. These reactions have also been reported in those who have eaten chocolate, milk, barley, rice, wheat, strawberries, citrus fruits, melons, bananas, tomatoes, spinach, corn, potatoes, and soybeans. Almost any given food type can cause a problem, depending on the person.
