Yes, I get what you are saying, and No, I cannot eliminate that I will have additional and/or future bone loss due to decreased estrogen levels and the effects of age. But I am very certain of the reason for my bone loss that was diagnosed and surgically removed; 2 massive tumors and Parathyroid hormone levels off the charts, with skyrocketing blood calcium levels leached from my bones and deposited in my kidneys. A very textbook scenario. Although I cannot say that I would not have post-menopausal bone loss, I wouldn't safely recommend that all postmenopausal women begin treatment.
