My Dexa was -2.86. I have had a number of hard falls and at least 1 a few weeks before my scan. No bones were broken . After the scan I was presrcibed zolendronic acid (a yearly dose given though IV injection) I didnt bother so i would love to know why have i not any broken bones in spite of osteoporosis ? I have been using weights for the last 20 years and doing loads of high impact exercises all my life and only recently started eating a calcium sensible diet . I am now 64 ( female, height of 5'4" and BMI of 20).....so maybe excercise does have an impact on making bones stronger!!
It sure is a puzzle. I think it would be worth some investigation to find out why.
Part of my spine is -4.3 so a pretty bad result.
I am being super careful not to fall now but in the past I have fallen and had some very bad ones without breaking any bones.
The bone density scan is only one key in diagnosis. It does not show what the strength of your bone is. You could have bones considered borderline osteoporotic, but if they are flexible (i.e. strong) you are unlikely to have a "fragility" fracture.
