Yellow urine in patients with hepatitis B can be seen as jaundice, but yellow urine can also be seen in normal people who drink less water, so you can drink more water to see if the urine is still yellow, and you can also look at the patient’s white eyes to see if there is significant yellowing, and yellowing of the white eyes is also caused by jaundice. For further confirmation, urine tests can be performed to see if the urobilinogen is significantly elevated, and blood tests can be taken to test the liver function. A significantly elevated bilirubin level in the liver function can also confirm the diagnosis of jaundice from the laboratory level. Patients with hepatitis B who have significant hepatocellular damage or bile duct obstruction may have abnormal bilirubin metabolism, as evidenced by yellowing of the urine, yellowing of the eyes, and in more severe cases, yellowing of the skin, and in those with more pronounced yellowing of the skin, itching of the skin all over the body may also occur.
