It is better to eat the following foods after appendicitis surgery, namely, liquid food, soft food, vegetables, fruits, and soy products. After the surgery, patients must gradually transition their diet. At the beginning, they can eat liquid food, such as millet porridge, rice porridge, pumpkin porridge and so on. If the liquid diet goes well, you can transition to semi-liquid diet and general diet. Patients can eat soft foods, such as cakes, rolls, vegetables and fruits, such as cabbage, spinach, bananas, etc., and soy products, such as tofu skin, tofu brain, etc. The above foods are nutritious, easily digested and absorbed, and will not lead to clinical symptoms such as abdominal distension. After the occurrence of appendicitis, the patient will have pain in the right lower abdomen or metastatic right lower abdominal pain, even accompanied by fever and abdominal distension. During physical examination, there will be fixed pressure pain at the McKinsey point, and even rebound pain and muscle tension, which are the typical manifestations of appendicitis and an important basis for the diagnosis of appendicitis. After the diagnosis of appendicitis, patients are advised to improve the examination in time, and if there are no contraindications to surgery, surgery can be performed.
