Unshaped stool may be caused by intestinal flora dysbiosis, intestinal inflammation, intestinal tumor and other reasons. 1. Intestinal flora imbalance: when patients have intestinal flora imbalance, it will lead to abnormal fermentation of food in the intestine, producing a lot of gas, stimulating the intestinal wall, leading to increased intestinal peristalsis, and the symptom of unshapely stool. 2. Intestinal inflammation: When patients suffer from intestinal inflammation due to intestinal infections, it will lead to the damage of intestinal mucosa, and the water and nutrients in the food can not be absorbed normally, which will lead to diarrhea, and the stool will not be shaped. 3. Intestinal tumor: when patients have intestinal tumor, the tumor will lead to the decrease of intestinal absorption function, and the water can not be absorbed normally; the tumor will also lead to the hypersecretion of intestinal digestive juices, resulting in the increase of fluid in the intestinal tract, which will lead to the failure of stool formation. There are many other reasons why the stool is not shaped. If the stool is not shaped, it is better to go to the hospital for examination in time to make a clear diagnosis, and follow the doctor’s advice for treatment in time to ensure the health of the body.
