What is the cause of diarrhea after intestinal tumor surgery

Many patients experience diarrhea after intestinal tumor surgery, which makes them very worried. Below, experts will explain the causes of diarrhea to you.

The main factors causing diarrhea after intestinal tumor surgery are the following two points:

1) Surgical factors: After the majority of the intestinal segments are removed for rectal tumors, changes in intestinal function, damage to the intestinal mucosa, and reduced intestinal mucosal absorption area can all cause diarrhea. On the other hand, during anal preservation surgery for low-lying rectal tumors, the need to fully expose the surgical field during low-lying anastomosis and sufficient anal dilation can cause sphincter damage. The anal sphincter function has not yet recovered in the early postoperative period, which can also cause diarrhea.

2) Intestinal flora imbalance: After intestinal surgery, the routine combined use of multiple antibiotics suppresses the normal intestinal flora that is sensitive to antibiotics, allowing certain drug-resistant strains and harmful bacteria to multiply in large numbers, causing flora imbalance and leading to diarrhea.

If you experience diarrhea after intestinal tumor surgery, don't worry too much. As long as you do a good job of postoperative care, follow the doctor's advice, and take proper care of your health, you can recover as soon as possible.
