Grade 1 fatty liver. Can i reverse it?

While doing an ultrasound check up due to irregular menstrual cycle I found out that I have grade 1 fatty liver. Findings is as follows. Liver- measures 13.9 cm. Echogenicity is increased.The portal vein caliber is within normal limits. There's no intrahepatic biliary dilatation seen.No evidence of any focal lesion seen in the liver.CBT at the porta is of normal caliber. I am not a person who is a junk fud lover,i eat limitedly.not over weight. Then how did I got this fatty liver? I was on isotretinoin in 2019 for 3 months and now I am again on that medication since last two months I have to take it two more months too.. did I got this because of this medicine? I am a person who have taken various medicines from birth to till now for various reasons.. coz I had low immunity so I always struggled with my health. Does it happen becoz of all the medicine I have taken my entire life? How can I reverse it? 29 yrs old-165 cm height-62 kg weight..
