Tooyoung, are you taking bio-identical HRT?  That's considered much safer than the standard which is manufactured from pregnant mares' urine.  

You did not do anything "wrong." Total hysterectomy is a major risk factor for osteoporosis. I believe that this surgery, combined with long-term use of the criminally overprescribed PPIs (which are now available OTC so that more people can harm themselves, thereby funneling ever-larger numbers to the osteoporosis-drug manufacturers' profit stream), was responsible for my own osteoporosis. As Kathleen points out, Fosamax is not appropriate for people with osteopenia ... and it's a toss-up whether it is even a good drug for people with osteoporosis. If you begin to take the drug at such a young age, you will be stuck with it for life, as any bone-density gains you might make will subside when you try and get off of it. These drugs, which belong to a class called bisphosphonates, have half-lives of up to ten years, meaning they remain in your system for a decade. Studies increasingly are showing that cumulative doses of this class of drug is predisposing people to catastrophic side effects, notably atypical femoral fracture, whereby the thighbone breaks upon little-to-no impact whatsoever, and osteonecrosis of the jaw (ONJ), a condition whereby mouth tissues are unable to heal following certain dental procedures and that is basically untreatable. You didn't say what the specialty is of the doctor who recommended Fosamax, but regardless of the answer, he or she apparently knows nothing about the drug's potential harms or the actual indications for it (such as they are).
