I was diagnosed with osteopenia when I was in my mid-40's. That was a big shock as I'd been active with hiking, skiing, and especially with strength training for at least 10 years. My mother had osteoporosis so I was at risk. My mother fell and broke her hip at age 68 and never fully recovered after that. I've been very frightened of this happening to me so I've been tracking the bone loss with periodic bone density scans. Fast forward to my early 60's and my bone density scan showed that I was in the osteoporosis range. I resisted taking any of the medications for a few years. I'd been taking calcium, magnesium, and vitamin D along with some other supplements. My Vitamin D blood level was tested and it was 17 nanograms/milliliter which is low. So my primary care doctor put me on a larger dose of Vitamin D and got it up to 50 nanograms/milliliter. That helped a little but it wasn't enough even though I changed my strength training to target hips and lower back. By age 64, I relented and started Fosamax. I tolerated it well for 5 years and went off Fosamax in late 2021. I had a bone density scan in December, 2021 and I'm back in the osteopenia range so that's a huge improvement. I work with a personal trainer and while that's a huge chunk of my budget it's worth it. I've made huge gains in strength in hips and back and last month I even hauled a wagon of logs for firewood up a hill!
