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. Common conditions managed by a gastroenterologist include colon polyps and cancer, irritable bowel syndrome (IBS), gallbladder disease, GERD or acid reflux, hemorrhoids, ulcers, and pancreatitis. The unique training  gastroenterologists complete provides them with the ability to care for patients with a wide variety of gastrointestinal ailments and restore them to optimal digestive health. Gastrointestinal issues can range in severity, which is why consulting a specialist can lead to a quicker and accurate diagnosis of complex gastrointestinal conditions. You may visit TPMG’s  Gastroenterologists if you experience abnormal bowel movements, have unexplained weight loss, frequent bloating or abdominal pain, have persistent heartburn, among other conditions.
