When assessing a client with cirrhosis, which stool color is typically reported due to lack of bile in the GI tract?

• A. Black and tarry
• B. Clay-colored or whitish
• C. Yellow-green
• D. Blood tinged

Answer: (B)

Stool color is driven by bile pigments that reach the intestine. Normal brown stool comes from stercobilin, a pigment derived from bilirubin in bile. When bile doesn’t reach the GI tract, such as in cirrhosis where bile production or flow is impaired (cholestasis), those pigments aren’t present in the stool. The result is pale, clay-colored or whitish stools.

This pale color signals that bile is missing from the intestinal contents, which is a common finding with significant liver dysfunction or biliary obstruction. In contrast, very dark, tarry stools suggest digested blood from a GI bleed, yellow-green stools can occur with rapid gut transit or bile present, and blood-tinged stools point to bleeding somewhere in the tract. The key concept is that absence of bile in the stool produces a clay-colored appearance.
