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.
Bile is stored in gallbladder and when you eat food, gallbladder releases bile into the small intestine (duodenum). The tube that carries bile from gallbladder to the small intestine is called bile duct. Whenever there is blockage or obstruction in bile duct, it enlarges in it size or dilates. The first symptom you may notice is pale colored stool and dark urine if bile duct is blocked, if the blockage progresses further it causes yellow discoloration of your eyes and skin.
