After appendectomy, the effects on the human body are manifested in the following aspects: First, the appendix, as an organ of the human body, can keep the intestinal function normal, and the intestinal resistance at a normal level. When the appendix is removed, the intestinal tract can become disordered and indigestion can occur. Therefore, after appendectomy, the patient should eat less and more often. A relatively light load on the intestines should be maintained so that the intestines have an adaptation process to gradually heal and achieve recovery. Secondly, after appendectomy, the impact on a person’s body is mainly in terms of complications. The complications that occur after appendectomy are not only localized scars and hard lumps, but also significant pain and itching on cloudy days and rainy days. In addition, after appendectomy can also cause liquefaction of subcutaneous fat, resulting in intestinal disorders that can affect the digestion and absorption of food in the intestine. In terms of diet, it is important to be light. If the abdomen is distended, it is best to massage the abdomen after meals to promote and regulate the normal peristalsis of the intestines. We must pay attention to proper rest after meals and avoid strenuous exercise quickly after meals, which can cause some lesions by increasing the burden on the intestines.
