I have no idea whether the HRT is helping because I haven't had a scan since I started HRT. I brought it up at my last appointment at the Menopause Clinic and the doctor said that I should have another scan in a couple of years time. He didn't think there was any need to for now.
My difficulty is that because I am severely affected by ME/CFS I can't follow the advice to do weight bearing exercise, so that is working against me. I also have hereditary haemochromatosis, as does my sister who has osteopenia. Haemochromatosis is also a risk factor as excess iron builds up in the bone marrow and somehow affects bone formation. That's something else that is working against my favour. TBH I'm not expecting to prevent more bone loss, just trying to make the situation “less worseâ€. I've always made sure I had an adequate calcium intake and as a child and young adult I was quite physically active until ME happened, so it was a bit of a shock to find out that I had full blown osteoporosis at 53. I'm also quite slight in build and always have been, so that's a risk factor too. I suppose everyone's risks are going to vary. All I can say is that if I could do the enough physical activity then I would. We can't change our DNA and we can't change our physical history, but there are things we can do that MIGHT help. For me it's HRT and vitamin D, but YMMV!
