I just discovered I have osteopenia when I went over the results of a bone density scan with my GP. I understand it is reversible. What do you recommend as a regimen to turn around the condition. I am 70 years old and have been physically active (marathons until 2004 when I had both my knees replaced) - I recently fractured my L-2 vertebrae (actually compression fracture from a fall) - and 2 weeks later contracted blood clots in my legs and lungs ( a large PE). I m wearing a body brace to immobilize the L-2, but I can use treadmill at the gym and light weights... thanks for whatever you can suggest!
