Depending on the recovery of gastrointestinal function of patients with acute appendicitis after surgery, the types of food that patients can eat differ. If the gastrointestinal function of patients with acute appendicitis has not fully recovered after surgery, but the patient’s abdominal infection is light, in this case the patient can eat a small amount of warm water, rice soup, noodle soup, which can not only relieve the patient’s symptoms of dry mouth, but also lubricate the gastrointestinal tract, promote intestinal peristalsis, and help the patient ventilate and defecate as soon as possible. Once the patient’s gastrointestinal function is completely restored and the patient has already exhausted and defecated, it is recommended that the patient eat a liquid diet such as thin porridge, noodles, rice flour and rice paste within 3 days after surgery. If the patient has no obvious abdominal pain or bloating symptoms after eating, he or she can eat a semi-liquid diet such as steamed buns, rolls, green vegetables, tofu, eggs, quail eggs, etc. After 3 days of observation, if the patient’s general condition is better, he or she can gradually return to a normal diet. A gradual diet will not increase the burden on the gastrointestinal tract, but will also facilitate the absorption of gastrointestinal functions and promote the early recovery of the patient’s condition.
