At what age should women start undergoing osteoporosis screening with a Dexa bone scan?

Women should generally begin osteoporosis screening with a Dexa bone scan at age 65. This recommendation aligns with guidelines from various health organizations, including the U.S. Preventive Services Task Force (USPSTF), which suggests that routine screening for osteoporosis should begin at this age. The rationale behind starting screening at 65 is based on the increased risk of osteoporotic fractures as age advances, particularly in women who are postmenopausal.

Bone density testing at this age can facilitate early detection of osteoporosis, allowing for prompt intervention to reduce the risk of fractures. Osteoporosis is often asymptomatic until a fracture occurs, making screening critical for early identification of at-risk individuals.

While the onset of menopause can affect bone density, routine screening is recommended to start at age 65 instead of younger ages, such as 50 or 60, unless there are other risk factors present that may warrant earlier screening.
