Need to know five causes of rectal bleeding bowel movements? If you have had rectal bleeding after a bowel movement, it can be quite scary. Although you should see a doctor if this continues, here are five things that can cause rectal bleeding.
- Anal Fissure. Fairly common yet painful, this cause of a rectal bleeding bowel movement is a condition where the lining of the anal canal is torn. Anal fissures can be caused by chronic constipation, straining to have a bowel movement, diarrhea that is prolonged, anal sex, overly tight anal sphincter muscles, or insertion of foreign objects into the anus. Signs of anal fissures include pain during or after a bowel movement, anal itching or burning, blood on the outside of stool, and blood on toilet paper.
- Hemorrhoids. These large clumps of tissue that contain blood vessels are present in everyone, but when they cause rectal bleeding bowel movements or discomfort, they are considered abnormal. Hemorrhoids can be caused from not eating enough fiber, prolonged straining, sitting on the toilet for long periods of time, or excessive heavy lifting. Some hemorrhoids are internal and cannot be seen by the naked eye, and some are external, protruding out of the anus. Internal hemorrhoids are generally painless. Signs of hemorrhoids include pain, and seeing drops of blood on stool after a bowel movement.
- Diverticulosis. This is a condition where the colon has little pouches or sacks called diverticula, which become inflamed causing rectal bleeding. Most people with diverticulosis have no painful symptoms and the rectal bleeding stops as fast as it starts, although it does tend to recur. Those with diverticulosis have more rectal bleeding than those with anal fissures. The cause of diverticulosis is thought to be weak walls within the colon.
- Colon cancer or polyps. Although only your doctor can determine if a polyp is cancerous or malignant, these can cause different types of bleeding depending on their location within the colon. Colon cancers and polyps located nearer the rectum tend to cause bright red bleeding bowel movements while those further away cause occult bleeding which is not as noticeable. Both types can lead to anemia over time.
- Colitis. Colitis is an inflammation of the colon, and can be caused by bacterial or viral infections such as salmonella and E. Coli, and many other dieases such as Crohn's disease. Colitis can cause diarrhea which is sometimes mixed with blood, abdominal pain, and rectal bleeding.
