Xray: when they say "loss of bone height" and or "demineralization", do they mean bone loss?

Bone: Hi. "Loss of height" usually refers to vertebral compression fractures. "Demineralization" is in the spectrum of bone mineralization that a bone density test measures. Human bone reaches peak mineralization at ~ age 30 for men & women, and is lost progressively after that (further accelerated loss at menopause for women). Fracture risk is lowest at peak bone mass at age ~30, & increases with loss.
