How to Prepare for a Gastroscopy

A gastroscopy is a common medical procedure used to detect and diagnose diseases such as esophageal and gastric tumors. Before undergoing this examination, patients must properly prepare their gastrointestinal tract. It is essential to empty the stomach and intestines of any food residue to ensure clear visibility during the procedure.

Patients are typically required to fast for at least 12 hours before the exam, avoiding both food and water. This fasting period allows the stomach to completely empty its contents into the intestines. In addition, bowel preparation may involve the use of cleansing laxatives or enemas to ensure that the intestinal tract is thoroughly cleared.

During the procedure, a flexible endoscope is gently inserted through the mouth, down the esophagus, and into the stomach. This advanced imaging tool enables doctors to examine the throat, esophagus, and stomach in detail. If any abnormal growths or suspicious lesions are detected, tissue samples can be collected for further analysis.

Biopsy results obtained during the gastroscopy play a crucial role in confirming a potential cancer diagnosis. Early detection through this method significantly improves treatment outcomes, making it an essential diagnostic tool in modern gastroenterology.
