The inability to eat after hemorrhoid surgery may be related to both the anesthesia and the surgical procedure, for example, when hemorrhoid surgery is performed under semi-body anesthesia, such as lumbar, sacral or epidural anesthesia, eating and drinking is generally prohibited within 6 hours after surgery. If the hemorrhoid surgery is a minimally invasive PPH procedure, the patient cannot eat for 24-48 hours after surgery because of the circular surgical incision in the rectum and the placement of an anal canal to prevent bleeding from the anastomosis after surgery, so the patient may only be able to take a liquid diet orally. Therefore, the specific time when patients can start eating needs to be combined with these factors, and the specific advice of the doctor in charge shall prevail.
