White stool is caused due to lack of bile which may indicate problem in liver, gallbladder, pancreas or intestine such as cysts, tumors, hepatitis, biliary cirrhosis, gall stones, narrowing of bile ducts, pancreatitis and sclerosing cholangitis. The side effects of antibiotics, antacids and antifungal drugs can also cause light colored stool. Eating too much rice can cause pale colored stool.
