What is a gastrointestinal endoscopy?

  Generally speaking, gastrointestinal endoscopy is a diagnostic tool, with the following specific details: Gastrointestinal endoscopy usually refers to colonoscopy and gastroscopy. These examinations are commonly used to diagnose conditions such as enteritis, gastritis, and gastric ulcers. The primary purpose of gastroscopy is to check for lesions in the duodenum or stomach. Before undergoing the procedure, patients should be aware of their health status, such as whether they have infectious diseases like hepatitis B or tuberculosis. For elderly patients, an electrocardiogram (ECG) should be performed prior to gastroscopy to evaluate heart function. It is recommended that patients undergo gastroscopy accompanied by a family member. Patients with pre-existing conditions such as hypertension or heart disease must inform the doctor of their detailed medical history and current symptoms before the examination. After gastroscopy, patients should wait one hour before drinking water and can consume liquid or soft foods after two hours. Prior to colonoscopy, patients should assess whether they meet the indications for the procedure. If peritoneal irritation signs or peritonitis are present, this examination should be avoided. After colonoscopy, patients should avoid alcohol and eating irritating foods. Physical activities are also not recommended to prevent intestinal irritation and discomfort such as abdominal pain.
