The stool is very soft and thin, can not pull out may be due to indigestion, intestinal parasitic disease, chronic enteritis, intestinal tumors and other digestive system abnormalities caused. 1. Dyspepsia: Eating too much greasy, cold and irritating food increases the burden on the gastrointestinal tract, leading to a decline in intestinal peristalsis, resulting in weak defecation and thinning of the stool by anal pressure during defecation. You can use drugs such as domperidone to promote peristalsis and improve the symptoms. 2. Chronic enteritis: it can be manifested as a feeling of falling in the anus and the symptom of having the urge to have a bowel movement but not being able to pull it out. It is generally recommended to use antibiotic treatment, such as cephalosporins, quinolones, etc. to control inflammation, and at the same time apply bifidobacteria to improve the intestinal flora, to reduce the related symptoms. 3. Intestinal parasitic disease: It is also easy to show that the stool is very thin and difficult to pass. After diagnosis, the patient can be treated with anthelmintic drugs, such as albendazole tablets. 4. Gastrointestinal tumors: if you have the symptoms of weak and fine stools for a long time, it may be caused by tumors and other organic lesions, which can be treated by surgical resection after examination. If you have any symptoms, you should consult the doctor in time, find out the cause of the disease and then treat the symptoms to avoid delaying the disease, and the drugs should be used under the guidance of the doctor.
