Gastroscopy is a key diagnostic procedure for the digestive system. It is the primary method for direct examination of the esophagus, stomach, and duodenum, allowing real-time observation of these organs to detect diseases or rule out their presence.
Gastroscopy is performed on an empty stomach.
You must not consume:
Food — at least 6 hours before the procedure
Water or any liquids — at least 3 hours before the procedure For morning appointments, do not eat anything after midnight.
For afternoon appointments, follow your doctor’s specific instructions regarding food and water intake.
Food residue in the stomach during the procedure increases the risk of aspiration into the respiratory tract and can reduce the accuracy of the examination.
