Stools may bleed for a variety of reasons. Common causes include:
- Hemorrhoids - enlarged veins in the rectum and anus that can cause itching discomfort and bleeding.
- Anal fissures - small tears in the lining of the anus that can be caused by straining during a bowel movement.
- Colitis - inflammation of the colon that can cause abdominal pain cramping and bloody stools.
- Diverticulosis - a condition where small bulging pockets form in the wall of the colon and can become inflamed and bleed.
- Infections - including bacterial or parasitic infections or viruses like norovirus.
It is important to speak to your doctor if you experience bleeding with your stools as it can be a sign of a more serious condition.
