Patients with appendicitis can eat normally one month after surgery, however, they should not overeat. Because open surgery or abdominal infection can lead to membranous adhesions on the plasma surface of the intestinal canal and even scar formation, which can easily induce intestinal adhesions after surgery. In addition, light, easily digestible food should be the main focus, and it is best to stay away from high-fat foods or fried and baked foods. Because these foods are carcinogenic, they are also not conducive to digestion and intestinal peristalsis, and can lead to habitual constipation, which is not conducive to patient or post-operative recovery. Physical exercise should also be performed after the diet to promote intestinal peristalsis and downward evacuation of intestinal contents.
