Gastroenterology is a medical specialty that focuses on the diagnosis and treatment of conditions affecting the digestive system, including the esophagus, stomach, small intestine, colon, and rectum. Gastroenterologists are medical doctors who have completed specialized training in the treatment of these conditions.
Gastroenterologists provide a range of preventive and diagnostic care services, including colonoscopies (procedures that use a camera to view the inside of the colon) and endoscopies (procedures that use a camera to view the inside of the body). They may also diagnose and treat conditions such as inflammatory bowel disease (IBD), gastroesophageal reflux disease (GERD), and liver disease. Gastroenterologists may perform surgery, such as removal of the gallbladder or repair of a hernia.
If you are experiencing symptoms related to your digestive system or have questions about your gastrointestinal health, it is a good idea to see a gastroenterologist for evaluation and treatment.
What are the disease conditions in Gastroenterology
Gastroenterology is a medical specialty that focuses on the diagnosis and treatment of conditions affecting the digestive system, including the esophagus, stomach, small intestine, colon, and rectum. Some common disease conditions that gastroenterologists treat include:
  • Inflammatory bowel disease (IBD): IBD is a group of chronic conditions, including Crohn’s disease and ulcerative colitis, that cause inflammation in the digestive tract. Symptoms of IBD may include abdominal pain, diarrhea, and weight loss.
  • Gastroesophageal reflux disease (GERD): GERD is a condition in which stomach acid flows back into the esophagus, causing heartburn and other symptoms.
  • Liver disease: Liver disease can be caused by a variety of factors, including viral infections, alcohol abuse, and autoimmune conditions. Symptoms of liver disease may include jaundice (yellowing of the skin and whites of the eyes), abdominal pain, and fatigue.
  • Irritable bowel syndrome (IBS): IBS is a common disorder that affects the large intestine and causes symptoms such as abdominal pain, bloating, and changes in bowel habits.
  • Peptic ulcer disease: Peptic ulcer disease is a condition in which sores, called ulcers, form on the lining of the stomach or small intestine. Ulcers can cause abdominal pain, nausea, and weight loss.
These are just a few examples of disease conditions that gastroenterologists may diagnose and treat. If you are experiencing symptoms related to your digestive system or have concerns about your gastrointestinal health, it is a good idea to see a gastroenterologist for evaluation and treatment.
Gastroenterologists, medical doctors who specialize in the diagnosis and treatment of conditions affecting the digestive system, may use a variety of tests to diagnose and treat these conditions. Some common tests performed in gastroenterology include:
  1. Colonoscopy: A colonoscopy is a procedure that uses a flexible camera, called a colonoscope, to view the inside of the colon and rectum. A colonoscopy can be used to diagnose and treat conditions such as colon cancer, polyps, and inflammatory bowel disease (IBD).
  2. Endoscopy: An endoscopy is a procedure that uses a flexible camera, called an endoscope, to view the inside of the body. Gastroenterologists may use endoscopies to examine the esophagus, stomach, and small intestine, and to diagnose and treat conditions such as ulcers, GERD, and Barrett’s esophagus.
  3. Upper endoscopy: An upper endoscopy is a procedure that uses an endoscope to examine the upper part of the digestive tract, including the esophagus, stomach, and duodenum (the first part of the small intestine). An upper endoscopy can be used to diagnose and treat conditions such as ulcers, GERD, and hiatal hernias.
  4. Capsule endoscopy: A capsule endoscopy is a non-invasive test that involves swallowing a small capsule with a camera inside. The capsule travels through the digestive tract and sends images to a recorder worn by the patient. A capsule endoscopy can be used to examine the small intestine and diagnose conditions such as Crohn’s disease and celiac disease.
  5. Liver function tests: Liver function tests are blood tests that measure the levels of certain enzymes
