My Husband (59) Has Fluctuating Bilirubin Levels - Need Help!

My husband ( 59) was detected with mild fatty liver condition in November '22. We consulted a specialist and he advised fibroscan, biopsy of liver and confirmed that alcohol consumption if any should be done away with and gave a huge list of medication. Some how the condition didn't improve much. Last year , June '23 my husband's ggt levels went extremely high n the entire lft report was bad and he was also diagnosed with high bilirubin ( jaundice). Since then, without wasting much time we consulted an Ayurvedic Dr. Since then things improved tremendously and even the fibroscan value started getting better. The lft reports were also improving, vut suddenly again this June we found that the bilirubin is getting sometimes higher and sometimes lower on different tests. Dr has changed the diet pattern and meds once again buu the surprising part is he has no symptoms of jaundice at all. No pain in the abdomen, no yellowing of skin or eyes. What could be the reason for this sudden fluctuations. Kindly suggest why this problem ???? Thank you.
