The digestive or gastrointestinal tract goes from the mouth to the anus. It is often called the GI tract.
Bleeding in the lower GI tract can happen anywhere in your small or large intestine. It can also happen in your rectum or anus. In some cases, it is caused by an infection, cancer, or inflammatory bowel disease. Or it may be caused by hemorrhoids, diverticulitis, or clotting problems.
