Does it hurt to have a gastroscope? How long does it take?

Gastroscopy is performed under general anesthesia, and the body generally does not feel pain. Gastroscopy is divided into painless gastroscopy and ordinary gastroscopy. A thin, soft tube with an endoscope is inserted into the stomach at the front end to observe whether there are lesions in the esophagus, stomach and duodenum. Gastroscopy generally takes about ten minutes, but each patient chooses gastroscopy in different ways, the degree of gastric lesions is different, and the specific time to do gastroscopy varies from person to person.
