Your liver got affected and so the enzyme levels are elevated.As fatty liver
is seen in CT,Alchohol can be the cause.
Stop drinking alchohol even though it is small in amount.
Get tests for Hepatitis A
,B,C & E viruses after consulting your Gastro enterologist.
Drink plenty of liquids,avoid oily foods.
Nothing to worry.
The levels will get subsided spontaneously in course of time
Wish you speedy recovery
