There are
many many things that can raise GGT and most of them are not serious.
Many drugs such as NSAIDs, Statins, some pain killers, etc., can raise GGT. In fact many hep docs do not even test for that enzyme because it is not specific at all. Usually when elevated GGT is the only thing in a liver panel that is elevated, it means nothing. Is your hubby overweight? That is another cause of GGT elevations.
