Your bones may be weakening long before you ever feel a problem. For many people, the first sign of bone loss isn’t a warning ache or stiffness—it’s a sudden fracture from a minor fall or everyday accident. By then, doctors say the damage may have been developing quietly for years.
Bone density naturally declines with age, but health experts warn that many people may need testing earlier than current screening guidelines suggest. In most countries, routine screening for women begins at age 65, usually with a DEXA scan, a painless imaging test that measures bone strength. Yet specialists say certain lifestyle factors, health conditions, and genetic risks can put people on the path toward osteoporosis well before that age.
Peak bone mass—the strongest your bones will ever be—is typically reached by the mid-30s. After that point, bone tissue slowly breaks down and rebuilds itself throughout life. But by the 40s, the balance can begin to shift toward gradual bone loss. For women, the transition to menopause often accelerates the process because of declining estrogen levels, a hormone that plays a crucial role in maintaining bone strength.
Research suggests that women can lose between one and two percent of their bone mass each year during the decade surrounding menopause. Without preventive steps, that gradual decline can lead to osteopenia—low bone density—or osteoporosis, a condition that makes bones fragile and prone to fractures.
Experts say several warning signs may indicate that someone should consider bone density screening earlier than the typical starting age.
One of the clearest signals is a fracture caused by minimal trauma. Breaking a bone after a simple fall, bump, or everyday activity can suggest underlying bone weakness. Family history also matters. If a parent or sibling developed osteoporosis relatively early—particularly if they experienced a hip fracture—it may indicate a genetic predisposition to weaker bones.
Early menopause is another factor that can raise risk. Women who enter menopause before age 45 spend more years with lower levels of estrogen, potentially increasing long-term bone loss.
Certain medications and health conditions can also affect bone health. Long-term use of corticosteroids—commonly prescribed for conditions such as asthma, autoimmune disorders, or severe allergies—can interfere with the body’s ability to build and maintain bone tissue. Chronic kidney or liver disease can also disrupt the body’s balance of minerals and vitamin D, both essential for strong bones.
Nutrition and energy balance play a role as well. Conditions linked to inadequate calorie intake, including eating disorders or relative energy deficiency in sport (often seen in highly active athletes), can weaken bones over time. Rapid or significant weight loss may also contribute. Some research indicates that people may lose about one to two percent of bone mass for every ten percent of body weight lost.
For people diagnosed with low bone density, the outlook is not necessarily bleak. Doctors often recommend lifestyle changes that help rebuild or preserve bone strength. These include consuming adequate calcium and vitamin D, engaging in regular weight-bearing exercise such as walking or strength training, and avoiding smoking or excessive alcohol consumption.
Balance training is also increasingly emphasized, as preventing falls can dramatically reduce the risk of fractures later in life.
Health professionals say the most important step is awareness. Understanding personal risk factors—and discussing them with a doctor—can help determine whether earlier screening is worthwhile. Detecting bone loss sooner gives people more opportunities to protect their bones and maintain mobility as they age.
In many cases, experts say, preventing fractures begins not with treatment, but with timely testing.
