I am 72 yrs old & accidentally found out that I may have osteopenia! This was never discussed by my family doctor who took me off meds 2 yrs ago - presuming that bones were good. I haven't had a bone density test done in 25 yrs. In researching into this disease, osteopenia can be caused by a med for brain tumour - successfully removed 2 yrs ago - dilantin. I wasn't told about this side effect of this drug. Any comments about this??
