During your first visit to a gastroenterologist, they will take your medical history and review any prior diagnostic tests that have been done. Then they may perform a physical exam during which they will evaluate your abdomen and other areas of the body related to digestion. Depending on their findings, they may then recommend certain tests such as blood work, imaging studies, or endoscopy procedures. Ultimately, the gastroenterologist will discuss their diagnosis and any potential treatment options with you directly.
