Place a towel under your face. Between the teeth is placed a mouthpiece made of plastic. This is necessary so that a person does not accidentally damage his pipe with his teeth. The doctor enters the probe to the root of the tongue, and then asks the patient to swallow saliva. During swallowing, the probe pushes further. When gastroscopy a patient is not recommended to talk.

After evaluation of the mucosal condition, the probe is removed. Do this slowly, so as not to induce a vomitive reflex. Conclusion is done immediately after the procedure. The doctor during a gastroscopy looks at the screen, where the mucous membrane of the esophagus, stomach and duodenum is displayed. After EGDU 1-2 hours a person may have discomfort in the throat. Anesthesia departs slowly. During this period, you do not need to eat food.
