The level of 125 is high but you have many reasons to have this level. Alcohol intake, weight gain and yes drugs can cause increase of the levels. I would advice you to quit alcohol , loose weight and avoid steroids
. Have the liver
functions rechecked after 4-6 months. You must also get an ultrasound
done and viral markers( hep B and Hep C) done.
You need not be alarmed with the value but this value does suggest an ongoing liver inflammation so if care is taken early we can avoid futher damage to the liver.
