What causes vaginal bleeding after bowel movement?

Generally, people think that blood in the stool is hemorrhoids. In fact, this is not the case, because there are some diseases that may cause bleeding in this situation, such as rectal polyps, rectal cancer, etc. When female friends have blood in the stool, they may encounter such a situation that the stool causes vaginal bleeding. Is this the case? Actually, it is not. This is mainly because the female anus and vagina are close to each other, so this situation is blood in the stool rather than vaginal bleeding caused by stool.

Blood in the stool is generally seen in lower gastrointestinal bleeding, especially bleeding in the colon and rectum, but upper gastrointestinal bleeding can occasionally be seen. The color of blood in the stool depends on the site of gastrointestinal bleeding, the amount of bleeding and the time the blood stays in the intestine. Blood in the stool accompanied by bleeding from the skin, meninges or other organs is often seen in blood system diseases and other systemic diseases. Such as leukemia, disseminated intravascular coagulation, etc.
