Can high total bilirubin lead to yellow urine?

High total bilirubin may lead to yellow urine. Total bilirubin is a form of bilirubin that, when its concentration in the blood increases, may be excreted through urine, resulting in darker urine color. Elevated total bilirubin is usually associated with abnormal liver function, biliary obstruction, or increased red blood cell destruction. The liver is the main organ responsible for processing bilirubin. When its function is impaired, the metabolism and excretion of bilirubin are affected, leading to an increase in total bilirubin levels in the blood. Biliary obstruction can hinder the entry of bilirubin into the intestine, causing it to accumulate in the bloodstream. Increased destruction of red blood cells can lead to more bilirubin production, exceeding the liver's processing capacity. These situations may lead to the excretion of bilirubin through urine, resulting in yellow or dark yellow urine. If abnormal urine color is found, especially accompanied by other symptoms such as yellowing of the skin or eyes, fatigue, loss of appetite, etc., it is recommended to seek medical examination in a timely manner. Doctors may determine the cause of elevated total bilirubin levels through blood tests, urine tests, or imaging examinations, and develop treatment plans based on specific circumstances. In daily life, maintaining healthy eating habits, avoiding excessive alcohol consumption, and regularly undergoing physical examinations can help maintain liver health.
