What condition necessitates earlier DEXA screening for women?

The need for earlier DEXA screening in women primarily arises from menopause combined with risk factors for osteoporosis fractures. After menopause, women experience a significant decrease in estrogen levels, which plays a critical role in maintaining bone density. This hormonal change increases the rate of bone resorption and decreases the rate of bone formation, leading to a higher risk for osteoporosis and subsequent fractures.

If a woman is at risk—due to factors such as advancing age, a family history of osteoporosis, a history of fractures, or certain medical conditions—earlier screening becomes essential to facilitate timely intervention, such as lifestyle changes or medication, to protect bone health. This proactive approach helps in early identification and management of osteoporosis, potentially preventing fractures and associated complications.

While being over 70, recent weight loss, and having a family history of osteoporosis are relevant factors to consider in assessing overall bone health, they do not individually necessitate the urgency of earlier screening as strongly as the combined influence of menopause and the associated risks for bone density loss.
