The diet of children with appendicitis after surgery should also be defined in strict accordance with the recovery of intestinal function. After the anal discharge, the child can be advised to eat a full liquid diet with few meals, mainly porridge, milk, soy milk, etc. After eating, appropriate activities should be carried out to promote downward peristalsis and evacuation of food. In addition, you should also pay attention to the situation of bowel movements, if normal bowel movements, you can gradually transition to a semi-liquid diet or a general diet. Take care to eat more vegetables and fruits, because they contain coarse fiber, which can promote intestinal peristalsis, and also have a lot of vitamins, which can help the healing of the incision after surgery. Advise patients not to overeat, as abdominal infections can easily lead to intestinal adhesions, and unreasonable dietary structure can also trigger the occurrence of intestinal obstruction.
