Dear welcome to healthcaremagic Blood in stool is not normal. Fresh blood in the stool is caused by bleeding in the digestive system. When the blood is fresh, it is generally caused by bleeding from the rectum or from the lower colon, because blood from higher in the gastrointestinal system (such as the esophagus or stomach) is usually clotted.

If the bleeding in the stomach and duodenum the stool may be dark brown called malena it may be hard in nature Please consult the doctor for diagonose the cause of Blood in stool and treatment accordingly Thanks
