The stool looks unshapely may be caused by dietary factors, gastrointestinal dysfunction, and organic lesions of the intestinal tract. 1. Dietary factors: If the patient consumes more high protein and high fat food in a short period of time, and usually consumes excessively oily and cold food, such as fried chicken, marinated meat, ham and sausage, ice cream, etc., which exceeds the gastrointestinal tract’s digestive and absorptive capacity, it will lead to the inability of complete digestion and absorption of food, and it will also easily lead to the passing of soft stools with more water, which will result in the appearance of unshapely stools. 2. Gastrointestinal dysfunction: a functional disease of the digestive system, mainly induced by mental factors such as emotional tension, excessive stress, etc., the patient may experience abdominal pain, diarrhea, stools do not form and other symptoms, part of which may be insomnia, anxiety. 3. Organic intestinal lesions: Organic intestinal lesions, such as intestinal polyps, ulcerative colitis, intestinal malignant tumors, will have an impact on intestinal function, resulting in diarrhea, abdominal pain, change in stool characteristics and habits. Patients who find that their stools are not shaped and accompanied by other discomforts should go to the hospital as soon as possible for appropriate examination and diagnosis, and receive treatment to avoid further affecting the digestive function.
