At this stage I'm assuming I will simply do another 12 month DEXA scan, which is available free in Australia every 12 months for patients with osteoporosis. I also intend to search for an endocronologist who specialises in HRT and osteoporosis and who may be able to advise me on the utility of other tests - such as CTX bone markers and REMS. I also want to explore a so called SERM treatment, tibolone, which is an alternative to HRT. I have a younger sister who is under the care of an endocronologist who put her on tibolone 3 years ago and - combined with weight lifting/ resistance exercises - has reduced her T score from - 3.5 to -2.8.
