Nice to see that you are concerned about your mother's health. The common cause for a high level of gamma GT
is related to alcohol intake. But other causes related to increase levels could be due to medications ( reason why her BP medicines should be checked again by her prescribing doctor, hepatitis/liver diseases such as cirrhosis
( which must not be necessarily of viral origin; so wish to know what hepatitis tests were done and if an abdominal/ liver scan was done. Biopsy could be helpful) and also some cardiovacular diseases such as myocardial infarction
(of course she would have presented with a heart attack
, so this is ruled out). Non the less it is better you get to an internist for further review ( so he can relate the cause of the elevated enzymes). Above causes can also raise the alkaline phosphatase
and also bone diseases need to be ruled out.
First of all if your mother is a heavy or moderate alcohol consumer it is high time she quits, if she is not, then other causes could be investigated.
Cheers and wish your mother a better health
