Stools - pale or clay-colored

Stools that are pale, clay, or putty-colored may be due to problems in the biliary system (the drainage system of the gallbladder, liver, and pancreas).


The liver releases bile salts into the stool, giving it a normal brown color. You may have clay-colored stools if you have a liver infection that reduces bile production, or if the flow of bile out of the liver is blocked.

Yellow skin (jaundice) often occurs with clay-colored stools, due to the buildup of bile chemicals in the body.


Possible causes for clay-colored stools include:

  • Alcoholic hepatitis
  • Biliary cirrhosis
  • Cancer or noncancerous (benign) tumors of the liver, biliary system, or pancreas
  • Cysts of the bile ducts
  • Gallstones
  • Medications
  • Narrowings (strictures) of the bile ducts
  • Sclerosing cholangitis
  • Structural problems in the biliary system that are present from birth (congenital)
  • Viral hepatitis

There may be other causes not listed here.
