Patients with appendicitis should also pay attention to the structure of their diet and not overeat during the first month after surgery. Because after open surgery, there may be different degrees of intestinal adhesions, overeating will lead to disorders of the digestive tract, affecting the peristalsis of the intestinal canal, which is also not conducive to the patient’s recovery, and some patients may even be prone to serious intestinal obstruction. In addition, it is also necessary to stay away from spicy and irritating foods in the 1 month after surgery, because there are some special patients who have scar growth, and spicy foods can easily lead to the aggravation of the scar. During or after the 1 month postoperative period, it is important to stay away from greasy and high cholesterol foods, and to focus on light and easily digestible foods, as well as to take appropriate physical exercise.
