When Should You See a Gastroenterologist for Abdominal Pain?
Abdominal pain can range from mild and temporary discomfort to persistent or recurring symptoms that require medical evaluation.
You may consider seeing a gastroenterologist when abdominal pain:

Not all abdominal pain is caused by a digestive condition, and the appropriate evaluation depends on the location, severity, duration, associated symptoms, and your medical history.
