How fast can billirubin go down? my total billirubin is 3 following all of the recommendations like staying hydrated eating only healthy food and a lot of fiber. taking a medicine like questran can my billirubin go down to 1.5 in a week?

This depends upon what caused the elevation. Do you have a history of Gilbert's Syndrome where your indirect bilirubin tends to be high but may vary? Was the direct fraction of the bilirubin elevated from a gall stone that has been passed? Were all your liver enzymes high from infection,alcohol excess,medication side effect,fatty liver? Are you taking Questran to lower lipids? To treat diarrhea?
