Gastroenterology is a specialized branch of medicine that focuses on the digestive system and its disorders. This includes the gastrointestinal tract—comprising the esophagus, stomach, intestines, colon, and rectum—as well as accessory organs like the liver, pancreas, gallbladder, and bile ducts. Gastroenterologists diagnose and treat conditions such as GERD, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), hepatitis, pancreatitis, ulcers, and gastrointestinal cancers. They also perform procedures like endoscopy and colonoscopy to aid in diagnosis and management. With expertise in digestion, nutrient absorption, and waste removal, gastroenterology plays a vital role in maintaining overall health.
