10 Common Causes of Blood in Stool

9. Anal Fissures

Anal fissures, small cuts on or near the lining of the anus, can lead to bloody stool. Most cases of anal fissures are nothing to worry about, and often resolve on their own within a few days. The main symptoms include bloody stools and sharp pain in the anal area during bowel movements.  Following a bowel movement, the individual may experience a burning sensation in and around the anus. Hardened stools — constipation — can worsen symptoms, so eating plenty of fiber can help. As with other ailments of the digestive system, drinking plenty of water can help the body digest food more easily and fully, and prevent constipation.
