Hello Doctor my father is facing from grade 2 hepatomagely. He has reduced his alcoholic consumption to twice a week. Will that help in curing.

Not necessarily. ANY continued use of alcohol in someone with alcoholic liver disease (alcoholic hepatitis, fibrosis or cirrhosis) is going to make it worse. While cutting down might help a little, it is not likely to completely resolve unless he completely stops drinking. If he cannot stop drinking completely, he should get professional help in doing so.
