Citric acid allergy symptoms and how to cope


One of the first symptoms experienced with a food allergy is itching. Contact with a food that you either have an intolerance to or are allergic to prompts the body to release histamine, a chemical compound made by the body to fight the allergy. Histamine causes physical sensations such as tingling and itching. The University of Maryland Medical Center reports the most common places to start itching with a food allergy is the lips, tongue and throat.

Inflammation can also be a symptom of citric acid intolerance or allergy. angioedema, or swelling of the lips, face, tongue and throat, are often associated with food allergies and can make it very difficult to breathe and swallow. Swelling can also move to other areas of the body such as the eyelids, ears, hands and chest in the form of hives. These red, raised, often itchy, bumps can appear in one spot or all over the body and depending on the severity of them can last for hours.
