Signs & Symptoms of Delayed Food Allergies

Delayed food allergies may not appear for hours or sometimes days. Delayed food allergies are discovered through a blood test and involve the immunoglobulin G antibody. It is difficult to determine which food has caused the allergy because by the time the symptoms appear, many foods may have been consumed. Often these symptoms begin mild but over a long period of time the reaction can progress to become intolerable. Many of the symptoms may be caused by other conditions. It is important to seek a physician's diagnosis.
