Why does the stool contain black blood clots?

When we defecate, we should actually pay attention to the shape and color of our stool. If we feel that our stomach is uncomfortable, then we must pay attention to these issues. For example, some people will find that there are black blood clots in their stool. In the face of this problem, we need to consider which digestive tract diseases are causing it. The following will analyze these reasons in detail.

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. In addition to digestive tract diseases, blood in the stool can also be seen in systemic diseases. 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. If upper gastrointestinal bleeding occurs and intestinal motility increases, brighter red stools may be discharged instead of tarry stools. When the small intestine bleeds, if the blood stays in the intestine for a long time, tarry stools may be discharged; when the amount of bleeding is large and the bleeding is discharged quickly, the stools will be dark red or even bright red or purple-red blood clots.

When bleeding occurs in the colon or rectum, fresh blood clots are often discharged because the blood stays in the intestine for a shorter time. When bleeding occurs in the upper colon, the blood and feces are often evenly mixed and appear maroon in color. When bleeding occurs in the sigmoid colon, rectum, or anus, fresh blood often adheres to the surface of the formed stool. Blood dripping after defecation, without the feces and blood mixed together, is often seen in internal hemorrhoids, anal fissures, rectal polyps and rectal cancer. Bloody or purulent stools may occur in bacillary dysentery, ulcerative colitis, colon cancer, and occasionally in amoebiasis.

The above is an analysis of the causes that may cause black blood clots in stool. Then we should pay special attention to these issues. In daily life. If you find yourself suffering from some illness. Or if there are any abnormalities in your body, you must pay attention to scientific treatment. Avoid impacts and harm as much as possible.
