Bowel polyps generally can not eat spicy food such as chili peppers within one month after surgery, usually after surgery the patient’s diet should be gradually transitioned to a normal diet. In the early postoperative period, patients should be fasted, and nutrients can be supplemented intravenously. After 48~72 hours of postoperative anal defecation, if there is no nausea, vomiting, abdominal distension and other adverse reactions, and after drinking water without discomfort, the patient can enter the liquid diet, but avoid entering the food that is easy to cause flatulence. One week after the operation, you should eat semi-liquid diet with little residue, and about 2 weeks, you can eat general food, but you should not eat spicy and stimulating food, such as chili, ginger, etc., so as not to stimulate the wound, resulting in bleeding. At the same time, you should not eat greasy, indigestible food, such as fried, barbecue food, so as not to aggravate the burden on the gastrointestinal tract. After one month after the operation, when the surgical wound is healed, you can consume chili peppers in moderation, but try to choose less spicy chili peppers, so as not to stimulate the surgical wound, resulting in recurrence of intestinal polyps. It is recommended that patients should follow the doctor’s instructions for postoperative diet and regular checkups, and should consult the doctor immediately if they have any discomfort during the period.
