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

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

What to expect at your health care provider's office

The doctor will perform a physical exam and ask questions about your medical history and symptoms. Questions may include:

• When did the symptom first occur?
• Does the discoloration affect every stool?
• What medicines do you take?
• What other symptoms do you have?

Tests that may be done include:

• Blood work, including tests to check liver function and for viruses
• Imaging studies such as an abdominal ultrasound
• Endoscopic retrograde cholangiopancreatography (ERCP)
