Food-induced gastrointestinal hypersensitivity (FGHS) is a condition causing severe abdominal pain, nausea, vomiting, and diarrhea after eating certain foods. It is believed to be caused by an abnormal response to food proteins and is most common in children.
Diagnosis of FGHS involves a detailed medical history and physical examination, as well as food allergy testing and elimination diets. In some cases, a blood test may be necessary to confirm the diagnosis.
Differential diagnosis may include other food-related allergies, food intolerances, irritable bowel syndrome, and other gastrointestinal disorders.
Treatment of FGHS typically involves avoidance of the offending food and elimination diets. Depending on the severity of the symptoms, medications such as antihistamines and corticosteroids may be prescribed to reduce inflammation and itching.
The prognosis for Food-induced gastrointestinal hypersensitivity is good with appropriate treatment. Most cases of FGHS can be managed with avoidance of the offending foods and proper diet management.
