What is a Gastroenterologist?

A gastroenterologist is a medical specialist who specializes in the diagnosis and treatment of digestive system disorders. This medical specialty covers a wide range of conditions, including gastrointestinal (GI) diseases, liver problems, and pancreas disorders.

Treatment may include medication, lifestyle changes, or surgery, depending on the specific condition and its severity.
