The sign and symptoms of food allergy are frequently overlooked by both patient and physician. Such signs and symptoms may have multiple possible causes. The most common food allergy signs and symptoms include:
*Tingling or itching in the mouth
*Hives, itching and flaring of eczema rash
*Swelling of the lips, face, tongue and throat or other parts of the body
*Wheezing, nasal congestion or trouble breathing
*Throat tightness, repetitive coughing
*Abdominal pain, diarrhea, nausea or vomiting
*Dizziness, lightheadedness or fainting
Having sudden allergic symptoms within an hour or two of eating a food should raise suspicious of a food allergy. A food allergy can cause chronic daily symptoms that may be more difficult to connect to particular foods.
