It is necessary to rest for 1~2 days or 1~2 weeks before doing hard work after having colonoscopy, and judgment should be made according to different conditions of patients. 1.1~2 days: If only a general colonoscopy is done and no biopsy is performed, you can rest for 1~2 days and then do physical work. Since the examination is performed with anesthetic drugs and the invasive operation of colonoscopy may cause intestinal mucosal injury, it is necessary to observe whether there is any abnormality for 1~2 days. 2.1~2 weeks: If the operation is carried out through colonoscopy, such as polypectomy or tumor biopsy, in order to prevent bleeding caused by poor wound healing, patients must be asked to try to do bed rest for 1~2 weeks before physical labor, during the rest period, we should pay attention to observe the color of the stools, and pay attention to the daily diet should be light. It is recommended that patients do not rush to do colonoscopy after strenuous physical activity, follow the doctor’s instructions for exercise recovery, while paying attention to dietary adjustments, if found to have bleeding abnormalities as soon as possible to seek medical attention.
