I understand your concern. 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 are Alcohol, Viral hepatitis, Non-alcoholic fatty liver disease, Chat Doctor. 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 dont take it, you need following tests: hepatitis virus markers, Ultrasound Abdomen and HIDE 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. Stay Healthy.
