About Gastroenterologists

Symptoms and complaints related to the digestive tract are some of the most common reasons we take over-the-counter medications, prescription medication or seek the advice of health-care providers. Gastroenterologists, or "GIs," are medical specialists with extensive training in diseases of the digestive tract. GIs can answer your questions, perform tests in making a diagnosis and prescribe the best course of treatment to help you feel better.
