Are there side effects from doing gastroscopy

Gastroscope is a thin and soft tube inserted into the stomach through the throat. It can directly observe whether there are lesions in the esophagus, stomach and other parts. If the operator is not skilled, it may cause esophageal mucosal damage or throat pain. At the same time, during the examination, it can also extract pathological tissues for biopsy to determine their nature. When extracting tissues, the operator is too violent, which may cause gastric mucosal bleeding.

After gastroscopy, if there is no pathological change in the stomach and no special discomfort in the throat, the patient can try drinking water first. If there is no choking symptom, you can eat a light and digestible liquid diet.
