Generally, about 2 weeks after colon cancer surgery, stool can be restored to near normal. However, whether the stool can be normal or not depends on many factors, as follows: 1. tumor growth site: after surgery for right hemicolectomy, the stool will return to normal faster; after surgery for left hemicolectomy or sigmoid colon cancer, especially sigmoid colon cancer, the stool will return to normal more slowly; 2. personal constitution: some patients will have intestinal disorder after surgery, and the stool will take a relatively longer time to return to normal; 3. postoperative diet: some patients do not follow the doctor’s requirements, eating stimulating and too cold food, such as drinking alcohol or cold drinks, will also prolong the recovery of intestinal function. The recovery of intestinal function depends on the surgical site and personal constitution, as well as whether or not to follow the diet according to the doctor’s requirements, and the type of diet also has some influence.
