A gastroenterologist is a medical doctor who specializes in conditions affecting the digestive system. They have expertise in the disorders and diseases that affect the gastrointestinal tract (esophagus, stomach, small intestine, large intestine, rectum, and anus) as well as the pancreas, liver, bile ducts, and gallbladder. Gastroenterologists diagnose and treat digestive disorders including liver disease, ulcers, irritable bowel syndrome, and cancers. They perform state-of-the-art diagnostic procedures, such as endoscopy of the upper GI tract and colonoscopy and sigmoidoscopy of the lower GI tract, including the intestines, rectum, and anus. Gastroenterologists are trained to perform a number of procedures used to help diagnose and treat these conditions, such as upper endoscopy, colonoscopy, biopsy, and the various endoscopic techniques needed to visualize the digestive system, including endoscopic ultrasound. They also interpret the results of these tests and discuss treatment options with their patients. If you have ongoing belly troubles including pain, nausea, or bowel issues, you may see a gastroenterologist. Here are some reasons to consider seeing a gastroenterologist:
- Ongoing diarrhea
- Blood in the stool
- Unexplained changes in bowel habits, including diarrhea and constipation
- Abdominal pain or bloating
- Heartburn or acid reflux
- Difficulty swallowing
- Unexplained weight loss
