I went to this site you posted and found the discussion about bone formation and other important parameters beyond just 'density' really helpful. There are comments elsewhere on Mayo Connect about the difference between healthy viable bone (bone that has the ability to absorb shock or respond to muscle signals and allow unusual, dynamic movements) and just old bone that hasn't been shed and replaced. The old bone would look good on a DEXA
buy not actually be a sign of healthy bone. So what is picked up by a DEXA scan is only part of the story. That's encouraging to me because sound diet, exercise and sleep might be the controlling factors for supporting the other parameters of healthy, non-brittlle, living bone and worry a bit less about DEXA X-rays?
