Dear S E Johnson
I am also a newbe and male. OK, I am considerably older than you - I am 55 - but that is still much too young to be having Osteoporosis problems (I have osteoporosis in the spine and osteopina in the hip and have had three rib fractures in the last 18 months with no major stress to cause them
My Testosterone is fine for my age, which probably means it is similar to yours if yours is a bit down, which suggests to me its is NOT about testosterone levels).
Also, my blood calcium count is normal. But just because one has calcium in one's blood does not mean that calcium being taken from one's bones is not a problem. Maybe the good count in one's blood is because it has been taken from one's bones.......
I am convinced that my vit D deficiency is part of what has caused it for me. I would say get that checked if you have not already done so.
My approach is not to think about wheel chairs, but what I need to do to get my bone strength back. It is complicated but the science on this is moving forward quickly and, with the right information, some pretty good decisions can be taken now to help.
All best in your road to regaining bone strength. Clant
