Patients with appendicitis who opt for minimally invasive surgery are now five days post-surgery, and the function of the intestinal canal has basically recovered, so they can eat normally through the mouth, but pay attention to a whole liquid or semi-liquid diet, because too much food or overeating can easily induce intestinal adhesions or even intestinal obstruction after surgery. Therefore, in the five days after surgery, we should mainly eat light and easily digestible food, most commonly porridge, noodles, ravioli, etc. Adequate supplementation of high protein, including animal and vegetable proteins, can promote wound healing and recovery. In addition, it is important to eat less and more meals, to be active after eating, and to eat more fruits and vegetables, because coarse fiber vegetables can promote intestinal peristalsis and prevent postoperative constipation.
