What is white stool?
Although the color of stool can be affected by different foods and medications, it is typically brownish due to digestion of bile salts, digestive agents made by the liver and stored in the gallbladder.
A reduction or absence of bile salts can cause the stool to become a pale clay-like color. Bile salt production can be reduced due to severe liver disease such as hepatitis or cirrhosis. The passage of bile salts into the intestines can be prevented by blockages of the bile ducts inside or outside of the liver due to inflammation, gallstones, or external compression. Pain, especially in the right upper abdomen, fever, nausea, itching, and yellowing of the skin and whites of the eyes (jaundice) can also occur with these conditions.
Medications containing aluminum hydroxide can turn the stool white, as can barium, a white substance sometimes used to help show the digestive tract on X-ray.
Stool is not normally white and you may require emergency treatment in some situations. Seek immediate medical care (call 911) for serious symptoms such as severe abdominal pain, high fever, significant vomiting, seizures, changes in mental status, or sudden behavior changes. Symptoms of dehydration such as decreased urination, increased thirst, fatigue, and light-headedness, also require immediate medical care.
Seek prompt medical care if you have white stool unless a specific cause, such as prolonged antacid use or a recent barium study, can be identified. White stool can be associated with a serious medical condition.
