Barretts vs. Gilberts and a high bilirubin count

I have Barretts with a bilirubin count of 1.4. My primary doctor told me I also have Gilberts. Can the high bilirubin be mainly for my Barretts and not just the Gilberts? I also have a high level of LDL Cholesterol Calc of 111. My primary doctor does not seem concerned with my levels and said my labs were good. Should I be worried?

I have an endoscopy done every two years (this November in fact) My digestive health doctor gave me the Barretts diagnosis.

Please tell me your opinion.
