In general, you can return to your normal strength on the same day after the gastroscopy. Gastroscopy is divided into general gastroscopy and painless gastroscopy. Painless gastroscopy means that gastroscopy is performed under anesthesia. Gastroscopy is a non-invasive operation in which the operating mirror enters the intestine through the esophagus or anus to diagnose intestinal diseases, and at the same time, it can be used to cut out pathology and remove polyps, etc. In general, normal physical activities can be resumed 2-3 hours after the anesthesia wears off after the gastrointestinal examination, but attention should be paid to the appropriate amount and degree of exercise. If the removal of polyps or the excision of pathological tissue may have to avoid heavy physical labor. Before performing gastroscopy, it is important to keep an empty stomach, and before performing colonoscopy, an enema should be performed to keep the digestive tract open and facilitate the diagnosis of the disease.
