Gastroenterology primarily examines the function and structure of the gastrointestinal tract. Common diagnostic procedures include gastroscopy, colonoscopy, abdominal ultrasound, CT scans, MRI scans, blood tests, and stool tests. Gastroscopy allows direct visualization of the gastric mucosa, enabling detection of lesions such as ulcers, inflammation, and tumors. Colonoscopy is used to examine the interior of the colon and rectum, identifying abnormalities such as polyps, inflammation, and bleeding. Abdominal ultrasound evaluates the shape and structure of organs such as the liver, gallbladder, pancreas, and spleen. CT and MRI scans provide more detailed imaging information, aiding in the diagnosis of complex digestive system diseases. Blood tests can assess indicators such as liver function, kidney function, and electrolyte levels to evaluate overall health. Stool tests can detect infections, bleeding, or the presence of parasites.

If you are planning to undergo gastroenterological examinations, it is recommended to fast beforehand, typically refraining from food and drink for at least 8 hours prior to the test. Inform your doctor about all medications you are currently taking, including prescription drugs, over-the-counter medications, and supplements, so the doctor can determine whether any should be temporarily discontinued. Wear loose and comfortable clothing to facilitate the examination. If you have any pre-existing medical conditions or allergies, be sure to inform your doctor. It is also advisable to have a family member accompany you on the day of the examination to provide necessary assistance afterward.
