Why is an gastroscopy performed?
A gastroscopy may be useful in cases of persistent or recurring upper abdominal discomfort, severe heartburn, difficulty swallowing, nausea or vomiting, as well as in cases of suspected inflammation, ulcers, bleeding or tumors in the upper digestive tract.

Procedure
A gastroscopy is performed using a flexible tube (endoscope) with a camera and light source at its tip. The examination is performed under sedation and is painless. You lie on your side while the gastroscope is carefully inserted through your mouth and esophagus into your stomach and duodenum. The camera allows for a detailed examination of the lining of the stomach and intestines to detect any abnormalities. If necessary, small tissue samples can be taken, polyps removed, or bleeding treated. The actual examination takes about 20 minutes, and the entire procedure, including preparation and recovery, takes approximately 1 to 1.5 hours.

Preparation
Your stomach should be empty for at least six hours before the examination. Clear liquids are permitted up to two hours beforehand. Any discontinuation of blood-thinning or other medication should be discussed with your GP beforehand.

After the examination
Immediately after the gastroscopy, you will be monitored briefly until the sedation wears off. Your throat and pharynx may be temporarily irritated, and you may experience mild bloating or belching. Eating, drinking, and taking medication are usually possible immediately after the examination. If tissue samples were taken, you will receive the results later. After an examination under sedation (propofol), you must not drive for 12 hours.
