Your results are not very high.
Detailed Answer:
Hello!
Thank you for the query.
First of all you can not compare yourself to any other person on this planet. Every human has a way different body, different body mass, different body ingredients and for sure different liver. Liver is a main aim of the alcohol. It changes it due to chemical reaction. Alcohol causes liver injury, liver cells destruction and liver enzymes secretion to the bloodstream. This is what we can detect. ALT, AST, GGTP are nothing more than a products of liver cells destruction. More alcohol you drink at once, more liver enzymes can be detected to the bloodstream. CT contrast and painkiller both can have some impact to liver.
And finally, your results are not very high. Just typical for regular alcohol drinker.
I suggest you to avoid alcohol for a month or so. I am pretty sure you will get much lower results.
Hope this helps.
Regards.
