Currently, patients undergoing hemorrhoid surgery at home and abroad generally do not control their diet, and those undergoing local anesthesia and sacral anesthesia can generally eat and drink normally after surgery. For lumbar anesthesia and epidural anesthesia, the diet should generally be abstained for 6 hours. If the surgeon requires a controlled diet after surgery, please follow the doctor’s instructions. On the day of surgery, because of the low activity and the influence of pain and anesthesia, the diet on that day should be easy to digest, light and non-greasy, with less gas-producing ingredients (such as soy products and milk), and the amount can be slightly reduced compared with the usual diet. In order to prevent stooling on the day of surgery, those who usually have more frequent and normal stools should not eat a large amount of coarse fiber diet on the day after surgery.
