Well, I have a somewhat skeptical attitude that osteopeinia is not real. I found out I had it over ten years ago. I've been taking calcium for 25 years, been exercising for longer, mostly impact for the majority of the time. I couldn't take Fosomax and was on Evista on and off for 3 years. I stopped taking it because of the side effects. I've lost 10% of my bone density in my spine in the last 3 years; no amount of calcium has helped. Both my mom and grandmother had this. I am thin and Caucasian, both apparently risk factors.
Right now I am waiting to discuss the results of some tests to make sure I am an OK candidate for Reclast. I am praying I can take this treatment without problems, because I don't want to be on my way to becoming my grandmother, who lost 3-4 inches in height and never was the same after she fractured her hip. I'm extremely conscious of what could happen when I am riding, x country skiing, or even just walking on the icy snow. It's not going to stop me from doing this stuff, but it's making me even more cautious than usual.
