Asymptomatic until fracture occurs.
Diagnosis based on history of prior fragility fracture or low bone mineral density, which is defined as a T-score ≤-2.5.
Screening is based on individual risk factors, including female sex, maternal history of fragility fracture/osteoporosis, older age, low body mass index (<20-25 kg/m²), body weight <58 kg, weight loss of >10% of body weight, androgen deprivation treatment (in males), aromatase inhibitor treatment (in females), corticosteroid use, tobacco use, and kidney stone disease.
Fall prevention is first-line therapy.
Bisphosphonates are first-line pharmacologic therapy for postmenopausal women and men.
In postmenopausal women, estrogen is considered only for those at high risk for whom nonestrogen medications are inappropriate.
