Welcome to HCM!
I appreciate your concern for the elevated
bilirubin with normal liver enzymes.
Normally bilirubin that is produced by the breakdown of old red blood cells is detoxified by conjugation in the liver. In Gilbert's syndrome this
detoxification process is less resulting in increased level of bilirubin with normal enzymes indicating that there is no underlying liver disease of
hemolysis.
Gilbert syndrome is a benign, familial disorder characterized by intermittent
jaundice in the absence of hemolysis or underlying liver disease.
The high bilirubin level could be due to the medication your have taken for ulcer.
Gilbert's syndrome doesn't require treatment.
The bilirubin levels in your blood may fluctuate over time, this usually goes away on its own, and it doesn't cause any ill effects.
If jaundice persists, consult your doctor.
I hope your doubts have been clarified.
Do you need more explanations, feel free to send your queries.
Regards!
