                      From diagnostic procedures to advanced treatment services, Physicians Regional Medical Group offers a range of care for digestive health. Gastroenterologists treat everything from ulcers and irritable bowel syndrome to colorectal and stomach cancers.

                      What is a Gastroenterologist?

                      A gastroenterologist specializes in the management of diseases of the gastrointestinal (GI) tract and includes treatment of other nearby solid organs such as the pancreas, gallbladder and liver. The gastrointestinal tract covers a broad area of the body, and symptoms affecting anywhere from the tongue to the rectum may be treated by a gastroenterologist. Common GI symptoms can include:

                      • Change in bowel habits such as constipation or diarrhea
                      • Consistent heart burn
                      • Abdominal pain or discomfort
                      • Difficulty swallowing
                      • Hemorrhoids
                      • Blood in stool
                      • Constant bloating
                      • Unexplained weight loss
