Gastroenterologist is a medical doctor who specializes in diseases of the digestive system, including the esophagus, stomach, intestines, liver, pancreas, and gallbladder. They diagnose and treat conditions through endoscopic procedures, imaging, lab tests, and medical management, often coordinating care with surgeons and other specialists. The term combines three Greek-rooted elements describing digestion, the gut, and the study of science, with a medical specialty suffix.
