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
- 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.
