What is the cause for increased bilirubin level?

Hi,

Welcome to icliniq.com.

Coming to the serum bilirubin, it is a breakdown product of hemoglobin. Any increase in bilirubin level is needed to be assessed for liver enzymes and HBsAg (hepatitis B virus surface antigen), to rule out the cause. Bilirubin can increase due to:

1. Increased breakdown of hemoglobin (raises indirect bilirubin).
2. Any damage to the living cells and any obstruction like stones (cause an increase in direct bilirubin and enzymes).

So, to confirm the problem, we need to do full liver function tests. Yes, you can do exercise at this level of bilirubin. Normal bilirubin is total bilirubin ranging from 0.1 to 1.2 mg/dL with direct being less than 15 % of the total bilirubin.
