The use of the BMD measurement is a classic example of “disease mongering:” turning healthy people into patients. This business-building approach begins by defining a disease with a test that will identify a large market of people as potentional customers. In this case BMD captures about two-thirds of women over the age of 40.
Osteopenia is a natural thinning of the bones that occurs as women age and does not result in unprovoked fractures. To repeat, this is a “natural thinning of the bones.” The mineral content of bones decreases due to physiological changes intended to maintain the highest efficiency of a woman’s body. Here is why it works this way: The biologic purpose of a woman is to reproduce offspring. To accomplish this, during her reproductive years she must store large amounts of minerals, including calcium, in her bones for the future growth of her fetus and for producing her breast milk for two years postpartum. Assessing her bones with a BMD test during these times will detect a plentiful supply of minerals.
After menopause a woman no longer needs these extra depots of minerals; they become unnecessary baggage. In the interest of efficiency, her body sheds the excess, and as expected, her BMD is found to be much diminished. Thus, she fails the test when she is compared with an inappropriate and unrealistic norm. “Normal” is defined by the bone status of a healthy 30-year-old adult female in her prime reproductive years. You can learn how these standards were created, and how the disease osteopenia was invented (with the help of three pharmaceutical companies), by listening to this very interesting National Public Radio (NPR) broadcast.
