The term “sarcopenia” is most often used to describe age-related loss in muscle mass and strength, and it is commonly considered analogous to osteoporosis. Yet unlike osteoporosis, which can be diagnosed based on widely accepted clinical criteria, sarcopenia is not recognized as a clinical condition even though it can impair physical function and contribute to disability, falls, and hospitalizations.
The daily rhythm of bone turnover is likely important for normal bone health, and recent research suggests that sleep apnea may be an unrecognized cause of some cases of osteoporosis. Sleep apnea’s effects on sleep duration and quality, oxygen levels, inflammation, and other aspects of health may have a variety of impacts on bone metabolism.
A review of more than a decade's worth of research on osteonecrosis of the jaw--when the bone in the jaw is exposed and begins to starve from a lack of blood--points to an increased risk for patients taking certain drugs for osteoporosis, anticancer drugs or glucocorticoids, those undergoing dental surgery, and people with poor oral hygiene, chronic inflammation, diabetes, or ill-fitting dentures.
