Final answer:
Acholic stool is the term for pale yellow/white or gray stool, occurring when bile doesn't enter the intestine and fats are improperly digested.
Step-by-step explanation:
A stool with pale yellow/white or gray color is often referred to as acholic stool. This can occur when bile does not enter the intestine, which can be indicative of certain disease states. Normally, bilirubin, the main bile pigment that gives stool its characteristic brown color, is excreted into the bile and transformed in the intestine. However, if bile and thus bilirubin do not reach the intestines, it can result in an acholic stool that may have a higher fat content because fats are not being adequately broken down or absorbed.
