My previous post was not intended to be harsh or inaccurate. I am speaking from my own personal experience. I am quite petite and small boned. After my hysterectomy at age 22, I was thrown into a post-menapausal state. Later assessments showed great degeneration in my bone density. I became very proactive and searched for all natural methods to slow and reverse this process. For me the combination of diet, exercise, supplements, and a trial of Fosamax worked. I agree that it is a complex issue with no simple answer; however, it is better to become informed and seek solutions.
