Esophagogastroduodenoscopy

You are in need of gastroscopy when you have problems such as indigestion, pain in the upper abdomen, difficulty swallowing, weight loss, vomiting and bleeding, and when you develop sideropenic anemia (anemia due to iron deficiency).

On the day of the examination, it is necessary to come on an empty stomach, i.e. do not eat, drink or smoke!

Before the examination, your throat will be sprayed with a local anesthetic to reduce the sensation and vomiting reflex that may occur when the endoscope is passed through the throat. Gastroscopy is performed while lying on your side. After placing the mouthpiece (a small tube that you have to bite and hold with your teeth), the doctor will carefully insert the endoscope into the mouth through it. You will be asked to swallow so that the endoscope can more easily reach the esophagus and stomach. You can breathe normally during the test. When the endoscope is inserted into the stomach, air is usually blown through the tube to inflate the stomach, flatten the walls and see the stomach lining. At that moment, you may feel a little nauseous. A tiny camera on the top of the endoscope sends an image of the inside of your stomach to a screen where the doctor can see your esophagus, stomach and small intestine. If necessary, the doctor will take a sample of stomach tissue (bioptate) for pathohistological analysis and/or remove polyps. This is done with tiny instruments inserted through the endoscope and is mostly painless and quick. When the examination is finished, the endoscope is taken out quickly and easily. The results are ready the same day. During the examination, it is necessary to carefully listen to the advice of the doctor and nurse in order to make the procedure as pleasant as possible. In case of a biopsy, you will receive the findings, i.e. the pathohistological diagnosis (PHD), later.
