Acholia or hypocholia^[1] is pallor of the feces, which lack their normal brown colour, as a result of impaired bile secretion into the bowel.^[2] Acholia is a sign pointing to reduced or lacking flow of conjugated bilirubin into the bowel, as a result of a problem in the liver itself or in the biliary tree.^[3]

Ancient Greek: a + chole (without bile).

A condition in which little or no bile is secreted or the flow of bile into the digestive tract is obstructed. The acholia is a sign of many diseases, such as hepatitis. Acholia causes the color of feces to fade.^[3]
