What Causes Bright Red Blood After Bowel Movement Without Pain, and How to Deal With It?

Bleeding without pain after bowel movements can be confusing and worrying. Common causes may include non-disease factors such as improper diet and hemorrhoids, or disease factors like anal fissures, ulcerative colitis, and rectal polyps. Understanding these causes is crucial for taking appropriate measures.

1. Non-disease Factors

Improper Diet: Excessive intake of spicy and stimulating foods, such as chili peppers and Sichuan peppercorns, may irritate the gastrointestinal tract, leading to bleeding in stool without pain. The solution is not complicated, mainly involving adjusting dietary habits by reducing spicy foods and consuming more bland foods to help alleviate symptoms.

Hemorrhoids: A common cause, especially in individuals with chronic constipation. Hemorrhoids can cause local tissue damage, resulting in bleeding without pain. Symptoms can be relieved by using hemorrhoid cream or sitting in warm water baths, which help reduce discomfort.

2. Disease Factors

Anal Fissures: Although anal fissures usually accompany pain, they may sometimes manifest only as bleeding. Caused by poor bowel habits, they can be treated by sitting in potassium permanganate solutions to promote blood circulation and aid wound healing. In severe cases, surgical treatment may be required.

Ulcerative Colitis: A disease potentially caused by genetics or immune abnormalities, with symptoms including diarrhea, bloody mucus in stool, and sometimes abdominal pain. Treatment requires medical guidance and may involve drugs like sulfasalazine enteric-coated tablets. In severe cases, surgery may be necessary.

Rectal Polyps: Protrusions on the surface of the intestinal wall, potentially related to environment and lifestyle. When polyps rupture, they can cause bleeding in stool, usually without significant discomfort. Prompt medical attention is needed, and endoscopic minimally invasive surgery may be required for treatment.

Apart from the above causes, there may be other more serious conditions, such as rectal cancer. To ensure health, it is recommended to visit the gastroenterology department of a hospital for a detailed examination to identify the specific cause and receive targeted treatment. Regular physical examinations and paying attention to abnormal bodily signals are important measures for maintaining health. By understanding this information, we hope to help you better cope with and manage this situation.
