About Rectal Bleeds
Rectal bleeding is a symptom that can occur as the result of a number of different conditions. What causes it? In most cases, rectal bleeds are caused by hemorrhoids (enlarged veins in the anal area that can rupture and produce bright-red blood). However, rectal bleeding can be caused by many other things, including:
- Anal fissures (cuts)
- Inflammation (ulcerative colitis or irritable bowel disease)
- Colorectal polyps.
People who take warfarin or other blood-thinning medications may also experience rectal bleeding, especially if they take drugs like aspirin. Symptoms can vary, but often include:
- Bright-red blood coating the stool
- Dark blood mixed with the stool
- Black or tarry stool.
