I have had mitral valve robotic repair dec. 2013. Now they are telling me I have osteoporosis of spine and right hip. I am 66, and otherwise in good health, weigh 115, I am leary of drug side effects, especially with the recent heart surgery. I have a ring keeping the valve working. Dr. assistant, PA, wants to put me on Fosomax. for 2 years -2.9 spine, -2.6 rt. hip Dexa scan, other areas are osteopenia. I have read of serious side effects Can I treat with just vitamins, diet, exercise. Would I be foolish to do that? I am very sensitive to all drugs, fast metabolism.
