Gastroenterology is a branch of medicine that focuses on the digestive system and its disorders. This field studies organs such as the stomach, intestines, liver, and pancreas. Gastroenterologists, the doctors who specialize in this area, diagnose and treat conditions like acid reflux, irritable bowel syndrome, and liver disease. Patients often visit gastroenterologists for symptoms like abdominal pain, bloating, or changes in bowel habits. These specialists use various tests, including endoscopies and ultrasounds, to examine the digestive tract. By understanding and treating these issues, gastroenterologists help improve patients' overall health and quality of life.
