Top 5 Benefits of Gastrology Surgery Gastroenterology is the study of the normal function and diseases of the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts, and liver. It includes a detailed understanding of the normal function (physiology) of the gastrointestinal organs, including the movement of materials through the stomach and intestine (motility), digestion and absorption of nutrients in the body, removal of waste from the system, and function. Benefits of Gastrology 1. Appendicitis. When the appendix becomes infected and inflamed, it may be removed (appendectomy) under Gastrology. 2. Gallbladder disease. When there is a problem with the gallbladder -- usually gallstones -- the gallbladder may be removed. 3. Hernia. A hernia occurs when a part of the body (like the intestine) protrudes through a hole or weak spot in the wall of muscle or connective tissue that is supposed to protect it (like the abdomen). 4. Weight loss. Various types of bariatric surgery (for example, gastric bypass) may be performed to treat obesity. This surgery is usually performed by a specialist in bariatric surgery. 5. Diverticular disease. A diverticulum is a small pouch or pocket in the colon (large intestine). Researchers aren't sure why these develop. Sometimes they can become inflamed and cause pain (diverticulitis).
