Your bones are rebuilt every day, old tissue out and new tissue in. Somewhere in midlife, for millions of Canadians, that trade starts running at a loss. No ache, no twinge, no warning light. For most people, the first symptom of osteoporosis is a broken bone.
That is not a scare tactic; it is how the Public Health Agency of Canada describes the disease. Almost 2.5 million Canadians aged 40 and over were living with diagnosed osteoporosis in 2019 to 2020, and because it so often goes undetected, the real figure is higher. A bone density test is the only way to see it before it announces itself.
The bottom line. Osteoporosis is bone loss running faster than normal, and it produces no sensation until a bone breaks under a load it should have handled. The scan that detects it is painless, takes about fifteen minutes, and is covered by provincial health plans when a doctor orders it. Canadian guidelines point to testing at 65 and older, and earlier for anyone with risk factors. If you have already broken a bone from a minor fall after 40, you are most likely to be missed and most likely to benefit from asking.
Key takeaways.
Almost 2.5 million Canadians aged 40 and over live with diagnosed osteoporosis, and about 81 percent of them are women.
The risk of an osteoporosis diagnosis doubles every five years between the ages of 40 and 65, according to Public Health Agency of Canada surveillance data.
In 2019 to 2020 there were 156 hip fractures per 100,000 Canadians aged 40 and over, and more than one in five of those people died of any cause within the following year.
Only 15 percent of Canadians aged 40 and over had a bone density scan in the year after an osteoporosis related fracture, and only 21 percent of those aged 65 and over received bone protecting medication.
Osteoporosis Canada reports only 44 percent of people leaving hospital after a hip fracture go straight home.
Bone responds to load at every age, so movement, calcium, vitamin D and protein all still matter after a diagnosis.
What separates normal bone loss from osteoporosis risk factors that need attention?
Think of bone as a building under permanent renovation rather than a fixed frame. Specialized cells break down old bone while others lay down new, and through your twenties and early thirties the builders keep pace. Most people reach peak bone mass, meaning maximum bone size and strength, by about age 30, after which the balance tips slowly and everyone loses some bone as an ordinary part of ageing.
Osteoporosis is that loss outrunning normal. Bone turns porous and weaker, to the point where a fall from standing height, a hard cough or lifting groceries can crack it. The most common sites are the forearm, hip, spine, upper arm and pelvis.
Some risk factors should raise your antenna long before any sign appears. A parent who broke a hip. Corticosteroid medication such as prednisone taken for more than three months. Conditions that interfere with absorbing nutrients, including coeliac disease and inflammatory bowel disease. Early menopause. Smoking, heavy alcohol use and a very slight frame add to the pile. None of these guarantee anything, and all are worth saying out loud at your next appointment, in the same way you would raise any of the ageing symptoms that are not actually normal.
Why does a fragility fracture stay invisible until the moment it happens?
A fragility fracture is a break caused by a force that should not have broken anything, such as a fall from standing height. It is invisible in advance because bone loss has no sensation. Bones do not hurt as they thin, and you cannot feel density leaving your skeleton any more than you can feel your hair greying. Canadian surveillance data shows diagnosis risk doubles every five years between 40 and 65, all of it silently.
There are a few clues, and they are easy to write off. Losing height is the main one. Osteoporosis Canada notes that a loss of 2 centimetres measured by a healthcare provider, or 6 centimetres from your tallest adult height, may point to compression fractures in the spine you never felt happen. A newly stooped upper back suggests the same. So does a fracture from a minor fall after age 40, which most people file under bad luck when it is the disease introducing itself.
Fractures also arrive in sequences rather than isolation. Osteoporosis Canada reports a 20 percent risk of a second spine fracture within twelve months of the first, and more than half of hip fracture patients break something else within five years. The first fragility fracture is the loudest signal the body ever sends about bone.
How much does bone loss after menopause change the picture for women?
A great deal, and the numbers are lopsided. About 81 percent of diagnosed Canadian cases are in women, largely because estrogen protects bone. When estrogen drops at menopause, Osteoporosis Canada reports loss accelerating to 2 to 3 percent per year, which is a meaningful share of a structure you cannot see or feel.
Men are not spared; they are overlooked. They tend to be diagnosed later, fracture later and do worse afterward. Canadian data shows men are 1.5 times more likely than women to die of any cause in the year following a hip fracture. If you are a man reading this for a partner or a parent, the risk factor list applies to you unchanged.
Why does hip fracture recovery deserve more respect than it usually gets?
A hip fracture is not a broken bone with a cast and a timeline. In 2019 to 2020, there were 156 hip fractures for every 100,000 Canadians aged 40 and over, and more than one in five of those people died of any cause within the following year. Among survivors, independence is often what does not come back. Osteoporosis Canada reports that only 44 percent of people discharged after a hip fracture return directly home.
Which makes the next part frustrating. After a heart attack, roughly 80 percent of patients leave the hospital with medication to prevent the next one. After a fragility fracture, which specialists call a bone attack, the follow-up mostly does not happen. Only 15 percent of Canadians aged 40 and over had a scan in the year afterward, and only about 21 percent of those 65 and over received bone-protecting medication.
So if you or someone you love broke a bone from a minor fall recently and nobody said the word osteoporosis, the system probably missed it. You are within your rights to raise it and ask whether a scan makes sense. Since most fragility fractures start with a fall, pair that with what actually helps balance and falls prevention.
Bone health self check, not a diagnosis
□ I am 65 or older and have never had a bone density scan
□ I have broken a bone from a minor fall at any point after age 40
□ A parent of mine broke a hip
□ I have taken corticosteroids such as prednisone for more than three months
□ I have lost noticeable height, or my upper back has become rounded
□ I went through menopause before age 45
□ I have a condition affecting nutrient absorption, such as coeliac or inflammatory bowel disease
Any single tick is worth raising at your next appointment. This checklist prompts a conversation with a clinician and is not a diagnosis.
How much do calcium and vitamin D actually contribute?
They supply the raw material and the delivery system, and neither works alone. Calcium is the mineral your skeleton is built from, and it comes from dairy, fortified plant milks, canned salmon with the bones in and leafy greens. Osteoporosis Canada points most adults over 50 toward roughly 1,200 milligrams a day, mostly from food rather than pills.
Vitamin D lets you absorb that calcium, and Canadian winters make it close to impossible to get enough from sunlight for months at a time. That is why supplementation is standard advice here, and why vitamin D turns up so often among the hidden deficiencies behind fatigue. Ask your doctor or pharmacist what dose suits you rather than guessing from a bottle. Protein matters too, since bone is roughly half protein by structure. Smoking and heavy drinking both accelerate bone loss.
Movement is the piece people underrate. Bone strengthens in response to load, so weight-bearing activity such as brisk walking, dancing, stair climbing and resistance training sends the signal to keep building. Balance work such as tai chi earns its place separately, because it prevents the falls that turn thin bones into broken ones.
What does osteoporosis treatment look like if the scan finds something?
First, the scan itself. A bone density test, more formally a bone mineral density scan or DXA, is painless, takes about fifteen minutes, uses a very low dose of radiation and is covered by provincial health plans when your doctor orders it. You lie on a padded table while a scanning arm passes over your hip and lower spine. There is no injection and no enclosed tube.
Ask for the scan if you are 65 or older, or younger with any risk factor on the list above. Your doctor or nurse practitioner orders it.
Bring your history, including a parent's hip fracture, any break after 40, your height when younger, and every medication you take.
Get the actual result, not just a reassurance. Ask for your T score and ten-year fracture risk, and keep both.
Discuss medication if the result shows osteoporosis or high fracture risk. Prescription options either slow bone breakdown or stimulate new bone formation, and both are proven to reduce fractures.
Load your bones weekly with weight-bearing activity and resistance training, and add balance work to cut the falls that cause the breaks.
Sort the basics, meaning calcium mostly from food, a vitamin D supplement through the Canadian winter, and enough protein.
Which treatment suits you depends on your fracture risk and your other conditions, which is a conversation for a clinician rather than an article. What matters is that treatment exists, it works, and starting before the first break beats starting after the second.
What else do people ask about this?
Who should get a bone density test in Canada?
Canadian guidelines generally point to a bone density test for everyone aged 65 and over, and earlier for anyone with risk factors. Those include a fragility fracture after age 40, a parent who broke a hip, long-term corticosteroid use, early menopause, or a condition interfering with nutrient absorption. Your doctor orders the scan.
Does a bone density scan hurt?
No. A DXA scan is painless and takes roughly fifteen minutes. You lie on a padded table, usually fully clothed, while a scanning arm passes over your hip and lower spine. It uses a very low dose of radiation, far less than a chest X-ray, with no injection and no enclosed tube.
What are the early symptoms of osteoporosis?
Osteoporosis usually produces no symptoms until a bone breaks. The few clues are losing height, a newly rounded upper back, or a fracture from a minor fall after age 40. Bone loss itself has no sensation, which is why testing matters more than waiting for a signal that never comes.
Can you rebuild bone once you have osteoporosis?
You cannot fully rebuild what has been lost, but you can slow further loss and substantially cut fracture risk. Weight-bearing exercise, resistance training, balance work, calcium, vitamin D and protein all help. Prescription medications either slow bone breakdown or stimulate new bone formation, and both reduce fractures.
Do men get osteoporosis?
Yes. About 19 percent of diagnosed Canadian cases are in men, and outcomes are worse. Canadian surveillance data shows men are 1.5 times more likely than women to die of any cause within a year of a hip fracture, and are consistently less likely to receive follow-up testing or treatment.
How much calcium and vitamin D do adults need?
Osteoporosis Canada points most adults over 50 toward about 1,200 milligrams of calcium a day, ideally mostly from food such as dairy, fortified plant milks, canned salmon with bones and leafy greens. Vitamin D needs supplementing through much of the Canadian year. Ask your doctor or pharmacist about the dose.
