Spine bone density increased 11%. T score went from-3.9 to -2.8. Femoral neck bone density increased 7%. T score went from -2.6 to -2.0. After forteo, I was on reclast for several years until my doctor recommended Prolia several years ago. It took almost 19byears for the bone density in my spine to increase by 16% and my T score to go from -3.7 to -2.3. I was diagnosed with severe osteoporosis at the age of 41. Now, at the age of 60, I hope that these treatments will prevent me from having the spine and hip fractures that my mother had in her 80's.
