Patients with early fatty liver usually do not have yellow urine because liver function is normal at this time and most mild fatty liver do not have specific urinary routine abnormalities. If not managed carefully, fatty liver may progress to severe fatty liver and even the formation of cirrhosis. In this case, the total bilirubin will be found to be elevated and the urine will become yellow when the liver function is checked, so it is important to pay attention to the treatment of liver disease. If not treated early, the disease may worsen and gradually develop into jaundiced hepatitis such as yellow eyes, yellow urine and yellow skin. Therefore, it is important to pay attention to liver care. Usually, you need to check blood lipids, blood sugar, liver function and liver imaging regularly. If liver function abnormalities occur, timely liver-protective and anti-inflammatory treatment is needed.
