Stools that are thick at the beginning and then thin later are usually related to physiological factors, hemorrhoids, intestinal diseases and other reasons.
1. Physiological factors: usually associated with poor dietary habits, bad habits, such as eating dry and hard food in the early stage, and eating water-rich food in the later stage, which may cause the phenomenon of coarse stools at the beginning and then thin. However, after dietary and lifestyle adjustments, the symptoms will gradually decrease and no special treatment is needed.
2. Hemorrhoids: related to long-term sedentary, when the anal hemorrhoids produce edema, will affect the normal discharge of feces, resulting in stool from coarse to fine. If the constipation is serious, you can follow the doctor’s instructions to take oral laxatives, such as polyethylene glycol, lactulose and so on.
3. Intestinal diseases: such as colon cancer, polyps, etc., these diseases may cause intestinal obstruction, resulting in obstacles to the passage of intestinal contents, so the stool may become thin from coarse.
If the polyp is simple, polypectomy will be performed directly. When intestinal obstruction occurs, then laparoscopic surgery will be performed. For malignant tumors, systemic radiotherapy should be carried out after surgery to inhibit cancer cells.
There are many other reasons why stools start out thick and then become thin. If the symptoms persist, it is recommended to go to the hospital as soon as possible to get a clear picture of the cause of the problem and then treat the cause of the problem.
