What to do if i have blood in stool what could this be?

See a doctor: Blood in the stool is never "normal". However, most of the time it is not serious - hemorrhoids (swollen anal veins) are the most common cause. Warm baths with epsom salts and a mild cream like anusol can help those. However, blood in the stool may be indicative of a colon polyp or tumor or inflammation of the colon. If it is persisting you should see a doctor for an examination. Peter wilk, md.
