Yes. Anyone who is at risk of osteoporosis should have the test once they reach a certain age - that includes almost all women and some men as well.
Depends on age/risks. Bone density scan is recommended for screening of osteoporosis. However, it is generally not recommended in a young woman (age 38) unless there are risk factors for accelerated osteoporosis such as chronic steroid use, primary hyperparathyroidism, concomitant diagnosis of rheumatological disorders and/or other risk factors. For men, hypogonadism is a risk factor. D/w your doctor.
