What are the tests for gastrointestinal examination

gastrointestinal examination usually includes gastroscopy, colonoscopy, helicobacter pylori testing, fecal occult blood test, abdominal ultrasound and other examination items. Gastrointestinal examination can help detect gastrointestinal inflammation, ulcers, polyps, tumors, and other diseases. It is recommended to choose the appropriate examination method according to the doctor's advice.

Gastroscopy examination uses an endoscope to observe the condition of the esophageal, gastric, and duodenal mucosa, and can detect lesions such as gastritis, gastric ulcers, and early gastric cancer. Before the examination, fasting for at least 8 hours is required. Colonoscopy is used to observe the internal condition of the colon and rectum, and can detect diseases such as intestinal polyps, inflammatory bowel disease, and colorectal cancer. Before the examination, intestinal cleaning preparation is required. Helicobacter pylori testing is performed through breath tests, fecal antigen or blood antibody tests to determine the presence of Helicobacter pylori infection, which is associated with the onset of gastritis and gastric ulcers. Fecal occult blood test is used to screen for gastrointestinal bleeding, which has a suggestive effect on early detection of gastrointestinal tumors. It is necessary to avoid consuming animal blood products before the examination. Abdominal ultrasound can observe abdominal organs such as liver, gallbladder, pancreas, and spleen, and assist in the diagnosis of diseases such as cholecystitis and pancreatitis. Fasting is required before examination. If abnormal results are found after gastrointestinal examination, timely medical treatment should be sought for further diagnosis and treatment. Maintain a regular diet, avoid spicy and stimulating foods, consume moderate amounts of dietary fiber, quit smoking and limit alcohol consumption, control weight, and undergo regular gastrointestinal health check ups. When experiencing gastrointestinal discomfort symptoms such as abdominal pain, bloating, and changes in bowel habits, it is important to seek medical attention as soon as possible to confirm the diagnosis.
