Light stools - Definition

June 2017


Definition


In standard clinical practice, stools are qualified as light, pale, or clay-colored if they appear much whiter than normal. Usually, bilirubin, a degradation product, is expelled both in the urine, in the form of urobilin, and also in stools in the form of stercobilin. It is because of this brown pigment that stools are colored brown. In the absence of bilirubin degradation, the stools contain only small amounts of stercobilin and change color. This light coloring can be due either to liver problems relating to dysfunctional bile production, or insufficient excretion of bile in the intestine, notably in cases of bile duct blockage.
