I got a Dexa scan when I was 40 after being diagnosed with early menopause. It showed moderate osteopenia and I started taking HRT.
10 years later I thought I should have a repeat scan to see if my bones had got weaker. I asked my GP and was told 'no, you won't get another scan unless you have a fracture'. I paid to get one privately. It showed the osteopenia was worse now. The necks of my femurs were -1.9 and -2.2. Osteoporosis starts at -2.6.
So I am still on the HRT and trying to use vitamins, diet and trying to build bone in the gym but after reading that article I don't think I am doing high enough weights.
