The test for bone density is the DEXA scan. It is a special x-ray machine that determines the density of the bones at a couple of specific locations - usually the upper femer or hip and the lumbar spine. The density measured is then compared to young, healthy people's bone density, and also to the bone density of people your own age, giving a T-score and a Z-score (I forget which is which). The number of standard deviations from normal determines whether you are normal bone density, osteopoenic (slightly below normal), or have mild/moderate/severe osteoporosis.
Yes, Lyme can decrease bone density because it can interfere with nutrition, cause exercise intolerance, and mess with the hormones that regulate bone density.
Yes, I have moderate osteoporosis. There are things one can do to fix this once the cause of the problem has been addressed. Exercise, proper nutrition (protein, essential fatty acids, vitamin C, calcium, Vitamin D, magnesium, boron, etc.), adequate hydration, and balanced hormone levels (adrenal, reproductive, and thyroid) are all needed for strong bone density. When all of these things are at optimum levels, the bones will fix themselves, no matter what age a person is (my Mom was diagnosed with osteoporosis at age 70, and after the use of strontium and adequate nutrition, her bones recovered back to normal and she no longer has osteoporosis). The medications that are given to slow bone loss actually can make bone density problems worse - especially the bisphosphonates like Fosamax, Actonel, etc. - because they suppress the bone remodeling process that is required to improve bone density.
I hope this helps - take care,
