Stools - pale or clay-colored

Definition

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

Considerations

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 or if the flow of bile out of the liver is blocked.

Yellow skin (jaundice) often accompanies clay-colored stools.

Common Causes

Possible causes for clay-colored stools may include:

Alcoholic hepatitis
Biliary cirrhosis
Cancer or benign tumors
Cysts
Gallstones
Medications
Sclerosing cholangitis
Strictures (narrowings)
Structural problems in the biliary system that are present from birth (congenital)
Viral hepatitis

This list may not be all inclusive.

Call your health care provider if your stools vary from the normal brown color.
