Stools in thin stripes and small amount may be a normal physiological phenomenon, but also may be caused by intestinal diseases, hemorrhoids and other pathological reasons. 1. Normal physiological phenomenon: if the amount of diet is small or the food is too fine, the formation of stool is small, which may lead to the phenomenon of thin stripes and small amount of stool. 2. Intestinal diseases: when there are intestinal tumors, intestinal polyps and other intestinal diseases, due to the narrowing of the intestinal lumen to make it difficult to pass stools, there may also be the phenomenon of thin strips of stools and low volume. 3. Hemorrhoids: Hemorrhoids are the phenomenon of engorged and enlarged veins in the lower rectum or anal canal, which may lead to obstruction of passage of stools, and the phenomenon of small amount of thin stripes of stools may occur. Once the phenomenon of thin stripes and small amount of stool occurs, you need to go to the hospital for further examination of colonoscopy, tumor markers and other items to find the cause.
