Can high levels of direct bilirubin cause white stool color?

Elevated direct bilirubin levels may lead to white stool color, usually associated with obstructed bile excretion or liver disease. Direct bilirubin is a form of bilirubin secreted by the liver into bile. If its excretion pathway is obstructed, it may lead to a lighter or even whiter stool color. Obstruction of bile excretion is a common cause of elevated direct bilirubin and white stool. Biliary obstruction, bile duct stones, or tumors may hinder the flow of bile into the intestine, resulting in a lack of normal bilirubin staining in stool. In this case, patients may experience symptoms such as skin itching and jaundice. The treatment of biliary obstruction includes surgical relief of obstruction or placement of stents to drain bile, and the specific plan needs to be formulated according to the cause. Liver diseases may also cause an increase in direct bilirubin and changes in stool color. Diseases such as hepatitis and cirrhosis can affect the liver's ability to process bilirubin, leading to the accumulation of direct bilirubin in the blood. These patients usually have systemic symptoms such as fatigue and decreased appetite. Treatment should be targeted at primary liver disease, such as antiviral therapy for viral hepatitis or the use of hepatoprotective drugs to improve liver function. Some genetic metabolic diseases such as Dubin Johnson syndrome and Rotor syndrome can also lead to abnormal direct bilirubin metabolism. This type of disease usually occurs from a young age, manifested as chronic mild jaundice, and the color of stool may intermittently become lighter. This type of condition generally does not require special treatment, but regular monitoring of liver function is necessary. physiological jaundice in newborns may also present with mild elevation of direct bilirubin and changes in stool color, which are usually transient and can resolve on their own as liver function matures. If jaundice persists for more than two weeks or worsens, serious diseases such as biliary atresia should be ruled out.

It is recommended to seek medical examination in a timely manner when the stool color turns white and there is an increase in direct bilirubin. Doctors may recommend liver function tests, abdominal ultrasound, or magnetic resonance cholangiopancreatography to determine the cause. In daily life, attention should be paid to observing changes in urine color, maintaining a balanced diet, avoiding high-fat foods that burden the liver, taking appropriate rest to avoid fatigue, and following medical advice to regularly check liver function indicators.
