What's the matter with ulcerative colitis and bleeding in stool? The blood is bright red.

Ulcerative Colitis (UC) patients experience stool bleeding and bright red blood, which may be closely related to a variety of factors. First, it needs to be clear that ulcerative colitis itself causes extensive necrosis, ulceration, and bleeding of the intestinal mucosa. When these necrotic intestinal mucosal tissues are excreted with the stool, symptoms of mucus, pus and blood will appear. However, when the bleeding point is close to the anus, or bleeding occurs due to damage to the perianal mucosa during defecation, the blood may appear bright red.

In addition, if the patient also suffers from hemorrhoids, this is also a common cause of bright red bloody stools. When patients with hemorrhoids defecate, the increased pressure on local blood vessels can easily cause blood vessels to rupture, resulting in bleeding. This bleeding is usually bright red and may be accompanied by perianal pain.

In addition, dietary factors may also affect the blood in the stool in patients with ulcerative colitis. If the patient eats spicy food for a long time and does not drink enough water daily, this may cause difficulty in defecation, which may in turn damage the perianal mucosa and cause bleeding. In this case, the bleeding is usually less intense but may also appear bright red.

In general, the causes of bright red bloody stools in patients with ulcerative colitis may include intestinal mucosal bleeding caused by the disease itself, local blood vessel rupture caused by hemorrhoids, and perianal mucosal damage caused by dietary factors. When such symptoms occur, patients should seek medical treatment promptly, undergo relevant examinations to confirm the diagnosis, and carry out targeted treatment under the guidance of a doctor. At the same time, adjusting eating habits and lifestyle are also important measures to reduce bleeding and promote recovery.
