Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Liver enzymes may be raised because of various causes. In your case some may be more possible but in every case it requires evaluation of the cause. Most common causes of such liver derangement's are Alcohol,
Viral hepatitis, Non alcoholic
fatty liver disease, Drugs.
Gamma GT is most commonly raised due to alcohol intake and in case you take alcohol, you need to keep a control over it. If you don't take it, you need following tests: hepatitis virus markers,
Ultrasound Abdomen and HIDA scan. A lot many times, the liver dysfunction is due to Non Alcoholic Fatty Liver Disease (NAFLD). So, if you have any evidence of fatty liver in Ultrasound and your other tests are negative, this rise is liver enzyme would be attributed to NAFLD. For this you need to reduce your weight, reduce fat in diet. This is my personal opinion based on details available here. If you still have any other query, you may please ask me.
Hope I have answered your query.
Let me know if I can assist you further.
