My friends bowel movements consists of only milky whit fluids and blood. what could it be?

Liver or bowel prob: This is unusual and he or she needs to see a doctor right away. White or clay-colored stool is usually due to a liver problem. Blood in the stool is always concerning. Your friend may have inflammatory bowel disease, like crohn's disease or ulcerative colitis, and the white stool may be mucous. Be a good friend and get your pal to a doctor as soon as possible!
