A gastroenterologist is a doctor who specializes in the stomach, small and large intestine, and other digestive organs (liver, pancreas, bile ducts, and gall bladder). Gastroenterologists see patients in the clinic and hospitals and also perform the endoscopic treatment to get a clear picture of your GI tract.

If you are 45 years or above, having a family history of GI cancer, or if you have complained to your family physician about a digestive difficulty such as persistent abdominal pain, nausea, diarrhea, illness, bowel discomfort, or heartburn, there something that is changing your digestive system. In such a case, you need to visit a gastroenterologist.

Gastroenterologists are trained in diagnosing liver conditions up to some extent. A Gastroenterologist performs a liver biopsy to look for damage in liver tissues.

A doctor may want to perform an endoscopy if gastrointestinal bleeding is identified. Other tests might include blood work, ultrasound, CT scan, MRI, and liver biopsy.
