I was diagnosed with advanced Osteoporosis at my 42. After a negative reaction to bisphosphonates when I lost 8% more bone in six months, I was placed on a birth control pill and calcium. After about eight years I developed high BP. Ultimately we found that my BP was being driven by the synthetic progesterone in that pill. I moved to bioidentical hormones to protect my bones. Today, at age 69, I am greatly improved and only osteoporotic. Bioidentical HRT has saved my life.
