Welcome to HCM,
Your husband has high liver enzymes there are many causes for elevated liver enzymes
.Common one are alcohol toxicity, viral hepatitis
, drug induced.
But in your case if he has deranged Lipid profile
there may be fatty liver
or if he is taking drugs for it statins are known to increase the level of enzymes.
If he is taking alcohol or smoking
kindly stop completely. Try to keep near ideal weight and regular exercise and diet.
If only isolated rise in enzymes is there and no cause is detected it may not be harmful to you please take care of other factors.
Take care and Good Luck
