Gastroenterology

Gastroenterology is a medical specialty focusing on the digestive system and its disorders. This includes the gastrointestinal (GI) tract—from the mouth to the anus—and associated organs like the liver, gallbladder, pancreas, and bile ducts.

Gastroenterologists diagnose and treat conditions such as acid reflux, ulcers, inflammatory bowel disease (IBD), liver disease, and colorectal cancer. They also perform diagnostic and therapeutic procedures like endoscopy and colonoscopy.
