hello
I have gone through your question and understood your concern.
A GGT test may be ordered when someone has an elevated ALP level.
An ALP test may be ordered alone or as part of a routine liver panel to screen for
liver damage, even if no symptoms are present.
A GGT test may be ordered even when someone with a history of
alcohol abuse has completed alcohol treatment in order to monitor compliance with the treatment program.
An elevated GGT level suggests that a condition or disease is damaging the liver but does not indicate specifically what.
Elevated levels may be due to liver diseases, such as
hepatitis or
cirrhosis, but they may also be due to other conditions, such as congestive
heart failure, diabetes, or
pancreatitis.
They may also be caused by alcohol abuse or use of drugs that are toxic to the liver.
You didn't mention if you have any known liver diseases.
Anyway i can say that your lipid lowering medication can potentially cause drug-induced hepatitis and alter the liver panel tests.
At the other side
hepatotoxicity is one of the most deleterious side effects associated with antithyroid drugs(Graves disease treatement)
In these circumstances my advice for you is to consult a local gastroenterologist as soon as possible because it is necessary to investigate about your actual increased GGT,these thinks can not be done on line.
Elevated GGt do not cause thyroid problems but treating thyroid problems like Graves disease can cause high gamma enzimes.
It is very important to find the cause and than you can have the right treatement.
Hope thhis is helpful.
If you have other questions, feel free ans ask.
Regards.
