Clay Colored Stool

Normal stool is mostly brownish in color with different shades and texture depending upon the diet. However pale or clay colored stool is not a normal phenomenon. Clay colored stool indicates disorders of the biliary system, which includes the gallbladder, liver, and pancreas. The bile salts reach the stool through the liver which actually gives it a brownish color. In case the liver isn’t able to form enough bile or if the bile is not getting dispensed from the liver then the color and consistency of the stool shall change. However an abnormally colored stool once in a while is not a serious concern but if occurs often then it might be an indicator of a serious ailment.


If the pale colored stool is a result of hepatitis then the symptoms don’t occur till the liver damage has been done. Common symptoms are: darker than normal colored urine, pain in the abdomen, appetite loss and weight loss. Jaundice, fatigue and flu like symptoms can also occur. In jaundice the whites of eyes and skin turn yellow due to accumulation of the fluid and also causes clay-colored stool. Other symptoms are nausea and vomiting and tenderness of the abdomen.
