Osteoporosis: pathogenesis, diagnosis, and treatment in older adults.

ABSTRACT

Prevention of osteoporosis is a major health concern. Bone loss occurs throughout life in both women and men due to calcium deficiency, hormonal deficiency, and changes in bone formation. The diagnosis of osteoporosis can now be made prior to fragility fracture, allowing for prevention as well as treatment. Criteria for diagnosis of osteoporosis are reviewed, and a plan for the evaluation of secondary causes of osteoporosis is discussed. Also reviewed are prevention and treatment options such as exercise, calcium supplementation, hormone replacement, and new and investigational drugs.
