Hi and welcome to HCM,thank you for your query.
Such LFT fluctuations are expected after any viral hepatitis
infection and if you dont have any other symptoms,you dont have to be worried. You should just check for some other viruses,B or C and follow hepatoprotective diet. It means,avoid alcohol,smoking
and fats and drink plenty of fluids, eat fruit and vegetables. Antiviral
mediactions may be necessary in some cases but hep a is usually terated conservatively and it should pass in 1-2 weeks.
Wish you good health. Regards.
