Thanks for posting your query.
I am Dr.Ratnakar Kini and I am pleased to assist you.
If the liver damage
is due to intake of liver toxic medications, then stopping those medications would help in the reversal of the damage if it is early stage.
If the damage has been severe, then reversal may not be possible and a liver transplant
may have to be done.
Liver function test and PT /INR test should be done.
I hope that answers your question.
