I am taking Fosamax and Prempro. I have a bad family history of osteoporosis. My question is: Will these exercises with the weights affect the jaw bone and spine density? I have started to increase the hip density with medication alone, but the spine still is decreasing slightly, and the jaw is not measured in a bone density test.

The best thing you can do for all of your bones is to combine the medications that you are taking with exercise (both weight bearing and strength training) - plus, make sure you get plenty of calcium and vitamin D. This combination of therapies has been proven to help both the hip and the spine. I know your test results must be discouraging, but try to be patient - bone takes a while to change. We know that women who take Prempro and other hormone replacement therapies retain more teeth as they age than women who do not go on HRT or estrogen do. So you can assume that your medication is helping with bone density in your jaw.
