Alcohol intake does cause you liver enzymes to be elevated but there are other reasons too. Like viruses which attack the liver , some medications or simply being overweight can cause what is now known as NASH (non alcoholic steatohepatitis). You must get the ultrasound done , also you need to avoid alcohol and have you meds reviewed by your doctor. Also get viral markers- hep B and C done. One time alcohol binge would cause a sudden raise of liver function tests , however a long time sustained intake can cause problems.
