People with FPIES who rely on medical foods

FPIES is a type of food allergy that affects the gastrointestinal tract. Classic FPIES reactions typically occur two or more hours after ingesting the “trigger” food and typically involve profuse vomiting, diarrhea, and can progress to shock. Reactions can be severe and require immediate medical attention. Chronic FPIES reactions are typically characterized by increasingly severe/intermittent vomiting, chronic diarrhea and possibly progressing to an illness mimicking a severe total-body infection in addition to potentially difficulty gaining or maintaining weight. There are no simple tests to diagnosis FPIES. Additionally, there are no FDA approved therapies for the treatment of FPIES. The main treatments are avoidance of trigger foods with a personalized dietary plan that ensures proper nutrition.
