I've had osteoporosis since I was at least 47. Was deficient in Vit D. Kind specialist referred me for a DEXA scan on hearing my father was osteoporotic. He remained so all his life, but thankfully had been in the parachute regiment on National Service and was a very good faller so his injuries were quite limited.
I took Raloxefene first, which was great, but had to come off after developing a brain tumour, which may have been oestrogen-sensitive. Then tried Alendronic acid infusion - ghastly side effects and it ruined the veins in my left arm which are now hopeless for blood tests or canulas. Never again. Denosumab injections were fine and may have helped stabilise the bone loss.
Now at 66, I am not on anything. I am at least a stone heavier - I was too thin in my 30s, 40s and early 50s - and more muscular, though it's harder to keep the muscle. I used to swim a lot - I switched to walking much more, and Pilates with weights or machines. I row or scull 2x a week. I still have osteopenia in my hip but my spine is just clear.
I had some subsidised and useful nutrition advice from Westminster Poly students - the students used to see patients under supervision. Worth looking into in your area. Avoid low-fat milk, yoghurt, etc and have full-fat everything. Avoid acid-producing foods like red meat and asparagus. I eat a lot of green leafy vegetables, sardines with bones in them, and other fish. An orthodontist told me the side effects of the bisphorous drugs are far more common than reported (osteocronosis of the jaw).
For the ladies with severe osteoporosis, my elderly neighbour has an injection each week provided by the Royal Orthopaedic Hospital at Stanmore. This is rare, but seems to help. In my experience, hospital clinics are better than many GPs. We need national screening for such a common but potentially life-limiting condition.
