Hi, Welcome and thanks for asking. Bilirubin levels are related to hepatic function predominantly. Increased red cell break down or obstruction to bilirubin out flow can also increase it. In the present condition of hepatitis B carrier, the bilirubin increase is due to hepatitis. Inflammation and damage of the liver is the major cause for raised bilirubin. In your present condition, a raised bilirubin indicates time of hepatic damage and reduced period indicates time of improvement. If it increases beyond normal and persistently, it means it is progressing and risk of cirrhosis is more. At present hepatitis - chronic stage is present. Risk of hepatocellular carcinoma is present in future and routine liver examination is necessary annually. Any further queries, happy to help again.
