Hi Bibi.you didnt mention how high ALT is. 2x or 3x higher than normal is a sign of hepatic or biliary damageusually biliary obstrucuton or gallbladder
stones) It can be caused by alcohol or any other factor. More specific test for alcohol abuse
is GGT. If only ALT is raised and you consider that you are not heavy drinker then liver damage
iis probably minimal. Ultrasound
can visualize is there any sign of cirrhosis. YOu should do freuent liver enzyme test and stop drinking till values fall to normal range. If alcohol abstinence isnt enough then other possible cause should be found such as viral or autoimmune hepatitis
or biliar tree obstruction.
Wish you good health
