Bleeding in the stool may be associated with hemorrhoids, rectal polyps, etc., which need to be combined with clinical symptoms and other medical history to make a comprehensive judgment.
1. Hemorrhoids: anal lumps, and stool bleeding, the first consideration with hemorrhoids. Because hemorrhoids will cause perianal veins varicose, and will protrude outside the anus to form pimples, if the blood vessels spontaneously rupture, or because of fecal friction caused by rupture, will cause bleeding in the stool.
2. Rectal polyps: Rectal polyps are abnormal proliferation of tissues in the rectum, if the rectal polyps are larger and closer to the anus, they may detach from the anus and form a semicircular ball of meat, that is, a pimple. Moreover, rectal polyps can be congested, edematous and eroded, so bleeding in the stool may occur from time to time.
Bleeding in the stool with a pimple in the anus, it is recommended to consult a doctor in time to clarify the cause of the disease, and then through drugs or surgery for targeted treatment.
