The issue of eating after appendicitis surgery depends mainly on the lesion of the appendix at the time of onset. For acute simple appendicitis, a liquid diet, such as vegetable soup, rice soup or enteral nutrition solution, can be consumed on the first day after surgery, 10-20 ml each time, 5-6 times a day. After the second day of anal discharge, you can continue to eat a full liquid diet, the amount can be slightly increased, and the number of times can also be slightly increased. After the third day, if there is no abdominal pain or fever, you can transition to a semi-liquid diet, such as eating steamed eggs or noodle soup, and the number of times and amount can be increased. If the appendix is septic and perforated, which is more serious, the issue of postoperative fasting should be based on the advice of the doctor at that time, do not enter hard food and stimulating food, especially try not to eat hard food within one week after surgery to prevent serious complications such as postoperative intestinal fistula.
