America’s bone health is quietly headed for a $19 billion crisis

Half of adults over 50 have weak bones, fractures kill one in five hip fracture patients, and a looming doctor shortage means prevention may be the only way to keep an avoidable cost spiral from breaking the system.

Today, nearly 100,000 older Americans will fall. For many, that fall marks the start of a life-altering decline: a fractured hip, lost independence, even early death. 

We tend to think of these falls as accidents. But more often than not, falls and their consequences are a silent crisis decades in the making. 

Americans today are entering old age with more fragile bones than previous generations, and modern life is largely to blame. We are moving less, spending more time indoors, and getting fewer of the nutrients — especially calcium and vitamin D — needed to keep the skeleton strong. At the same time, the specialists best positioned to catch and treat bone loss are in short supply. 

The result: an aging population increasingly vulnerable to fracture, and a healthcare system increasingly ill-equipped to help. That makes prevention more critical — and more urgent — than ever. 

More than half of U.S. adults over ​age ​50 already have low bone ​mineral ​density or osteoporosis, a disease that weakens bones and leaves them ​prone to fracture. 

What makes bone loss especially dangerous is that it is silent. It does not hurt. It can progress for years without symptoms until one day it announces itself with a fracture. By then, the damage is already done. One in five adults dies within a year of a hip fracture. Many others never fully regain their​ prior level of​ independence. 

That is precisely why early detection and treatment are so essential – and why it is so concerning that access to that care is becoming harder to find. 

The number of specialists equipped to manage bone health, including endocrinologists and orthopedic surgeons, is not keeping pace with the rapidly growing at-risk population. The United States could face a shortage of more than 140,000 physicians by 2038. 

Even today, fewer than one in five patients receive appropriate osteoporosis care after a fracture — missing a critical opportunity to prevent the next, often more devastating, injury. 

The good news is that bone loss is often preventable. It is not a condition that suddenly appears in old age, nor is it only a problem for women after menopause. The choices people make in their 30s, 40s, and 50s can build — or erode — the bones they will depend on in later life. 

Prevention comes down to three basics. 

Start with calcium. The body does not produce calcium on its own, and when it does not get enough from food or supplements, it borrows from the skeleton — gradually degrading the very structure it needs to stay upright. Most adults need around 1,000 to 1,200 milligrams per day, an amount that usually ​can be ​met by including dairy foods​ ​​or fortified alternatives like soy or oat milk at each meal. 

Calcium, though, requires a partner. Without adequate vitamin D, the body cannot absorb calcium efficiently. Sunlight triggers vitamin D production in the skin, and even short periods of daily exposure can make a real impact. Egg yolks, fatty fish, and fortified foods are reliable dietary sources that add up over time. Supplements fill the gap for anyone who can’t get enough from sun or food. 

Then there is movement. Bones are living tissue, and they respond to the demands placed on them. Weight-bearing activities — brisk walking, climbing stairs, dancing, strength training — signal to the body that the skeleton needs to stay dense and strong. Without that stimulus, bone gradually breaks down. Even 30 minutes of weight-bearing exercise most days of the week can make a meaningful difference over time. 

None of these steps is particularly demanding or costly. But each is easy to overlook — partly because the consequences of neglect can take decades to surface. 

Prevention is within reach for most Americans. What’s missing is the urgency to treat bone health as the public health priority it is — before the first fall.
