What mean white stools?

Answer 1

The stool gets the normal brown color from bile, excreted from the liver into the small intestine. (for digestion). So if this bile does not come into the small intestine due to a liver problem (less / no production, e.g. in hepatitis) or an obstruction along its path, the stool colour turns white. (E.g. choleductolithiasis - gallstone). Some of the causes are rather serious, so a physician should be consulted promptly.
