"What Other Conditions Besides Hemorrhoids Can Cause Rectal Bleeding?"

Blood in Stool

Blood in stool refers to blood discharged from the anus, which can be caused by hemorrhoids, anal fissures, colorectal polyps, rectal prolapse, and other diseases. Apart from hemorrhoids, rectal polyps, rectal prolapse, colitis, gastric ulcers, and other conditions can also lead to blood in stool. It is recommended to seek medical attention for a definitive diagnosis.

1. Hemorrhoids: Pathological hypertrophy and displacement of the anal cushion, along with stagnation of blood flow in the subcutaneous vascular plexus around the anus, form a mass, encompassing internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. Internal hemorrhoids or the internal component of mixed hemorrhoids primarily exhibit jet-like bleeding, while external hemorrhoids primarily bleed, with bright red blood visible in severe cases.

2. Anal Fissure: Small ulcers formed after a split injury to the skin layer of the anal canal below the dentate line, with typical clinical manifestations including pain, bleeding, and constipation during bowel movements. When anal fissures occur, they may cause local blood vessel rupture, resulting in blood in stool.

3. Colorectal Polyps: Abnormal growths protruding into the lumen of the colon, including neoplastic polyps and non-neoplastic polyps. Neoplastic polyps are usually attached to the intestinal mucosa, and their rupture can cause bleeding. Non-neoplastic polyps are often rubbed against during bowel movements, leading to rupture and bleeding, most often in bright red color.

4. Rectal Prolapse: Partial or complete downward displacement of the rectal wall. When the rectum protrudes outside the anus, friction on the mucosa can cause bleeding, often in bright red or dark red color.

In addition to the above-mentioned diseases, conditions such as leukemia, thrombocytopenic purpura, atherosclerosis, and Hodgkin's lymphoma may also present with symptoms of blood in stool. It is recommended that patients maintain proper food hygiene in their daily lives, consume fresh fruits and vegetables, and ensure smooth bowel movements.
