Can high total bilirubin lead to yellow urine

High total bilirubin may lead to yellow urine. Total bilirubin is the main pigment in bile, and when the level of total bilirubin in the blood increases, it may be excreted through the kidneys, leading to darkening of urine color. Elevated total bilirubin is commonly found in liver and gallbladder diseases such as hepatitis, bile duct obstruction, or hemolytic diseases. The liver is the main organ responsible for processing bilirubin. When liver function is impaired, bilirubin cannot be metabolized and excreted normally, leading to an increase in bilirubin levels in the blood. Bilirubin is filtered through the kidneys and enters the urine, resulting in a dark yellow or brown color. In this case, yellow urine is usually accompanied by yellow staining of the skin and sclera, which is a manifestation of jaundice. In rare cases, yellow urine may be related to other factors. For example, consuming large amounts of foods rich in carotenoids or certain medications may also cause changes in urine color. But such situations are usually not accompanied by an increase in total bilirubin. If the urine color continues to be abnormal and accompanied by other symptoms such as fatigue, decreased appetite, or abdominal pain, timely medical examination of liver and gallbladder function should be sought. When yellow urine is found, it should be observed whether there are other symptoms accompanying it, and self judgment should be avoided. It is recommended to maintain sufficient water intake, reduce high-fat diet, and avoid alcohol consumption. Regular liver function tests can help detect liver and gallbladder diseases early. If yellow urine persists or worsens, it is necessary to seek medical attention promptly to determine the cause and not delay treatment.
