Acholic stools

Definition Return to top

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 Return to top

Jaundiced (yellow) skin often accompanies clay-colored stools.

The liver excretes bile salts into the stool, giving it a normal brown color. Obstruction to the flow of bile out of the liver (you may see the word "cholestasis"), or liver infections like viral hepatitis, may produce clay-colored stools.

Common Causes Return to top

Possible causes for clay-colored stool result from problems in the biliary system, and may include:

Cancer or benign tumors
Strictures (narrowings)
Congenital anatomic problems (present at birth)
Gallstones
Cysts
Medications
Sclerosing cholangitis
Biliary cirrhosis
Protein or infectious infiltration
Alcoholic hepatitis
Viral hepatitis (A,B, or C)

The underlying cause should be investigated.

What to expect at your health care provider's office Return to top

The medical history will be obtained and a physical examination performed.

Medical history questions documenting pale or clay-colored stools in detail may include:

Time pattern
- When did this first occur?
- Is every stool this way?
Medications
- What medications are being taken?
- Have you changed medication in any way?
Associated symptoms
- Is there any abdominal pain?
- Is there any jaundice?
- Has there been darkening of the urine?
- Is there diarrhea?
- Is there any fever, chills, or night sweats?

The physical examination will include emphasis on the abdominal region. The findings may indicate a need for surgery.

Your doctor may perform:

A full history, noting any medications or habits, such as heavy drinking or intravenous drug use
Blood work, including liver function tests and tests for viruses
Imaging studies, such as an abdominal ultrasound
Endoscopy studies with a long, flexible scope passed through the mouth to the small intestine (ERCP, endoscopic retrograde cholangiopancreatography)

After seeing your health care provider:
If a diagnosis was made by your health care provider related to pale or clay-colored stools, you may want to note that diagnosis in your personal medical record.
