Gastroenterologist: If you have some chronic GI issues that are not getting better on their own, you should get a consult to see a gastroenterologist. They specialize in GI issues. There are conditions that are not obvious on blood tests that require a scope with biopsies and microscopic examination. Endoscopy is a common and well tolerated procedure and may confirm a diagnosis.
