[Osteoporosis in premenopausal women].

In contrast to postmenopausal women diagnostic process and treatment of premenopausal osteoporosis in young women reamin poorly defined. A low bone mineral density in premenopausal women is not associated with the same risk of fractures as in postmenopausal women, therefore diagnosis requires not only densitometric examination but depends on the consideration of other risk factors. Most cases of premenopausal osteoporosis are associated with chronic diseases affecting bone metabolism. Treatment of the underlying disease may improve bone density as well as bone quality. Rarely, a bone-specific antiporotic therapy may be used, although quality evidence is scarce. This article will review current opinion on definition, diagnosis and treatment of premenopausal osteoporosis.
