Bloody stools: If your stools are normal brown in appearance with blood on the outside it could be internal hemorrhoids which are usually painless, do not bleed and can be missed on a rectal exam. These often result from constipation. Eat a healthy diet that promotes a healthy gut which includes lots of vegetables. Consider the Paleo Diet. If your bleeding worsens, persists, you feel weak, get dizzy go to ER.

Keep looking: Blood in stool is a warning sign. Brisk bleeding warrants emergency care. Causes of bleeding may be predictable (e.G rectal trauma), but evaluation is always appropriate. A rule of thumb (but not absolute): black stool means bleeding comes from upper GI tract; grape jelly stool from small bowel; silver stool from biliary tree; burgundy stool from right colon; red blood from left colon to anus.
