Women Are Often Told to Get This Bone Test at 65. One Doctor Says That’s Too Late

Osteoporosis rarely announces itself. It quietly thins bone year after year until a fall or a stumble ends in a break. An estimated 54 million Americans already have weakened bones, most of them women. Duke orthopedic surgeon Dr. Jocelyn Wittstein calls the disease deceptively patient, one reason so many women don’t think about their bones until they’ve already broken one. “It’s a silent disease until it’s not silent,” she said.

The Age Most Doctors Wait Until: 65

Most screening guidelines, including the U.S. Preventive Services Task Force’s, direct women toward their first bone density scan at 65, and insurance typically won’t cover one earlier without a documented risk factor. A federal review of screening data notes that age isn’t without critics, since osteoporosis can take hold well before a woman qualifies for a covered scan.

Wittstein Says Waiting Until 65 Misses the Real Window

Wittstein, an associate professor of orthopaedic surgery at Duke, argues the window that matters most opens earlier, at the menopause transition around age 50 or 51. “I think where it’s critically important is the menopause transition,” she said. Bone loss accelerates sharply in the two years before a woman’s final period, a stretch her patients rarely think to test for.

The T-Score Number That Reveals Your Fracture Risk

A DEXA scan produces a T-score comparing a patient’s bone density to that of a healthy 30-year-old. A score between 0 and negative 1 counts as normal. Between negative 1 and negative 2.5 signals osteopenia, weakened but not yet broken. Anything worse than negative 2.5 crosses into osteoporosis. That distinction shapes how urgently a doctor treats whatever the scan turns up.

Nearly a Third of Hip Fracture Patients Die Within Two Years

The stakes go beyond a cast and crutches. Wittstein puts the two-year mortality toll after a hip fracture at roughly 30 percent. A study tracking hip fracture outcomes found death rates climbing well into the double digits within just the first year, driven by the fracture itself and not only by a patient’s prior health.

Strength Training Signals Bone to Rebuild Itself

Wittstein points to strength training and impact exercise, think squats, jumping jacks, resistance work, as the most direct lever women have. These movements send a mechanical signal telling the body to lay down denser bone tissue. Stronger bone also improves balance, cutting the odds of the falls that cause most fractures to begin with. “Something is always better than nothing,” she said.

Calcium Isn’t the Only Nutrient Your Bones Need

Calcium gets the headlines, but Wittstein says three other nutrients do essential supporting work. Vitamin D helps the body absorb that calcium. Magnesium activates the vitamin D. Vitamin K then directs the calcium into bone for mineralization. A diet heavy in fruit, vegetables and fiber rounds out the anti-inflammatory foundation she recommends building alongside it.

Estrogen’s Quiet Role in Keeping Bone From Breaking Down

Estrogen normally slows the process that breaks bone down, so when levels fluctuate through perimenopause, that brake loosens. Wittstein says menopausal hormone therapy, prescribed mainly for hot flashes and night sweats, carries a lesser-known FDA indication for bone protection, since restoring estrogen also restores some of its anti-inflammatory effect on skeletal tissue.

Wittstein’s Case for Asking Doctors for Scans Sooner

Because insurance rarely covers a DEXA scan before 65 without a documented risk factor, Wittstein says women often have to make the case for themselves. Raising a family history of fracture, a prior break, or simply the start of perimenopause with a doctor can be enough to justify testing years ahead of the standard age, while there’s still time to slow what a scan finds.

Bone Loss Rewards Whoever Moves First

Osteoporosis produces no early symptoms, which is exactly why waiting for one is the riskiest strategy. Wittstein’s approach comes down to catching bone loss at the menopause transition rather than after a fracture forces the issue: track it with a scan, build it with strength training and key nutrients, and weigh hormone therapy where it fits. Even with osteopenia already present, she said, “you can still live a very full life.”
