Hello and welcome to HCM.
Thank you for your query.
Let me first give you all the normal values for the parameters you have mentioned.
-SGOT: 4-40 U/L (yours is slightly elevated -- 60.4)
-SGPT: 5-35 U/L (yours is slightly elevated -- 73.8)
-GGT: 5-50 U/L (yours is slightly elevated -- 113.4)
Your levels of the above parameters would normally indicate a
liver disease/condition, or alcohol-consumption related damage to the liver. As your other parameters are normal, it is quite clear that these parameters are elevated due to the alcohol intake.
Yes sir, beer can contribute to these levels as well. I would advise you to reduce or completely eliminate the consumption of alcohol before it causes any serious damage to your liver.
As mentioned by you, your other parameters are normal, which means you do not have any liver disease as of now. But the above mentioned parameters are high solely because of your alcohol intake, and will have to be normalized, which can take place by abstinence from alcohol.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
