Osteoporosis

First a brief review - in order to make maximum use of calcium in the development of bone, one needs vitamin D. Specifically one needs active vitamin D which can be gotten by getting some sun exposure (15 minutes a day in the northern latitudes in the head, face, neck tends to do it). Bone's uptake of calcium into bone growth processes is influenced by a lot of different factors such as body build, genetics, diet, medications, and the amount of "need" that is usually described as weight bearing activities. So the more you use your muscles and bone, the more likely it is that your bone will absorb and utilize more calcium.

Osteoporosis is the weakening of bone through a loss of calcium utilization. Women, especially Caucasian women who are post-menopausal and of slight build with little history of weight bearing exercise, are prime candidates. One of of four post-menopausal women will experience a bone break that significantly shorten her life or lower the quality of life. Ok - may be not so short a reivew.

When there is an unexplained (as in car accident) or suspicious bone break, that's what they look for.

Elevations in serum calcium can occur due to increased intake of calcium, or decreased utilization of calcium. The level here is so slightly above the reference limits that it would be difficult to say unequivocally that this is a problem result. That the vitamin D is low (again very slightly) is also difficult to interpret. It could be due to a range of issues including the medication you are currently on, the degree of sunlight exposure you have had lately, etc. My guess is that the physicians will want to err on the side of caution and put on you one of the bone enhancing medications such as raloxifene , alendronate, or the like.
