White Poop or Clay-Colored Stool. This type of poop can be described in many ways, including pale, clay-colored or even white. This white poop is present when the liver does not release enough bile salts into the stool in your intestines. This may occur due to bile duct blockages, gallstones or liver problems. Clay-colored or pale gray stool is usually a sign of a more serious problem.
It should be noted that bile is what causes our stools to be colored brown, which is the natural color of stools. A white bowel movement would usually indicate blocked bile ducts in your liver. An indicator of blocked bile ducts aside from white bowel movement will be pain in the upper right part of your stomach.
