Blood in the stool or with bowel movements is never a normal situation, although there are definitely causes for this kind of symptom that are not serious. However, since blood in the stool can also be a sign of more significant health problems, it is always best to see a physician who can take a more thorough history and physical exam to make sure there is nothing more serious going on.
Blood in the stool or associated with bowel movements can commonly be caused by hemorrhoids
, or enlarged blood vessels that are in the anal area. These can often be painless and a person may not even know he or she has them until they may have occasional mild bleeding
with bowel movements. Unless the bleeding becomes significant, there is no need for further treatment.
In addition, it is also possible for the anal area to develop a small tear or fissure. This can also lead to bleeding with bowel movements, but anal fissures are usually associated with significant amounts of pain with bowel movements.
Bleeding with bowel movements or blood in the stool can also be associated with things inside the rectum or colon, including polyps or abnormalities of the blood vessels. Although this would be a more unusual finding in a young adult, it is important to make sure that there is nothing in the lower GI tract that would require more urgent attention.
