Gastroenterology is a branch of medicine focused on the diagnosis and treatment of disorders related to the digestive system, which includes the esophagus, stomach, intestines, and liver. Gastroenterologists are specialists who manage conditions such as acid reflux, irritable bowel syndrome, and hepatitis. This field encompasses a wide range of procedures, including endoscopy and colonoscopy, to visualize and treat issues within the gastrointestinal tract. Patients often seek gastroenterological care for symptoms like abdominal pain, bloating, and changes in bowel habits, making it a vital area of healthcare for maintaining digestive health.
