AST/ALT level increase. Medicines?

I have got the whole body scan and found AST/ALT level increase in LFT. Past few months, I've been getting sudden pain in heart that remains for few seconds, and as per doctors advise, it's related to Gastrology. I've a habit of puking food, if large quantity is taken as it doesn't get digested properly but this happens once or twice a month. When I got these scans done, it was found the level increase of AST/ALT plus low cholesterol. Could you advise what should be the precautionary measure for LFT betterment? Is this something serious which I should be worried about or could easily be cured through medicines? I'm an occasional drinker ( 2 times a week with not more than 60) with past smoking history, quit 4 years back.
