1956, I have also been diagnosed with Gilbert's, my bilirubin fluctuates as well as my enzymes. I was told by the doctor to be careful not to get dehydrated, as that would cause it to dip.
I also have liver issues . I was diagnosed with gilbert's disease becasue of elevated level of unconjugated bilirubins. My liver enzyme levels were also all over the place. My GI doc said if my emzymes kept getting worse he would want to do a liver biopsy for liver disease as a precaution but he felt it was because of my celiacs. My enzyme are still off somewhat but not getting worse , and my bilirubins are still elevated. . The main thing is they are not getting worse.
