Physical reactions to certain foods are common, but in most cases, these symptoms are caused by a food intolerance rather than a food allergy. The two conditions are often confused because a food intolerance can cause some of the same signs and symptoms as a food allergy. A food allergy affects the immune system. Even small amounts of the offending food (allergen) can trigger a variety of symptoms, which can range from mild and mostly serve as a nuisance, to severe and life-threatening, requiring immediate emergency medical attention. On the other hand, food intolerance often affects only the digestive system and causes less severe symptoms, sometimes not needing medical care.   Furthermore, a person with food intolerance may be able to eat small amounts of the offending food without trouble and may even be able to prevent a reaction. For example, a person with lactose intolerance may be able to drink lactose-free milk or take lactase enzyme pills to aid digestion and prevent adverse symptoms, such as IBS. The causes of food intolerance include: • Absence of enzymes needed to digest food • Irritable bowel syndrome • Sensitivity to food additives   If you or someone you love is exhibiting the signs and symptoms of a food allergy, come get tested at Primary Care Center for a definitive answer!
