Men do get osteoporosis, but doctors often miss it

Yes, men develop osteoporosis. About one in four men over age 50 will break a bone due to osteoporosis in their lifetime. The disease thins bone tissue the same way it does in women, but men are diagnosed later and less often because osteoporosis is widely seen as a women's health issue. That delay matters: a man who breaks a hip from weak bones faces the same recovery challenges and loss of independence as a woman, but may not have caught the disease early enough to slow it.

Men lose bone density starting around age 30, but the rate accelerates after 70. Unlike women, who experience a sharp drop in bone density around menopause, men's bone loss is gradual. That slower decline can mask the problem until a fall or minor bump causes a fracture that should not have happened.

The reason men are underdiagnosed is partly medical habit: screening guidelines have historically focused on women, and doctors are less likely to order a bone density test for a man without a clear risk factor. But men with certain conditions — low testosterone, chronic kidney disease, rheumatoid arthritis, or a history of corticosteroid use — face real risk and benefit from early detection.

Key Takeaways

  • Men account for about one in four osteoporosis-related fractures in people over 50, but are screened far less often than women.
  • Men's bone loss accelerates after age 70, and a fracture from a minor fall or bump is often the first sign of the disease.
  • Low testosterone, chronic kidney disease, rheumatoid arthritis, and long-term corticosteroid use are major risk factors specific to men.
  • A bone density test (DEXA scan) is the only way to know if your bones are thinning, and your doctor may not order one without you asking.

Why men are at risk but often undiagnosed

Men build more bone mass than women during childhood and young adulthood, which gives them a buffer. But that advantage shrinks with age and certain health conditions. A man with low testosterone — whether from aging, cancer treatment, or a medical condition — loses bone density faster than a man with normal testosterone levels. Testosterone, like estrogen in women, helps maintain bone strength.

Chronic kidney disease is another major risk factor. The kidneys regulate calcium and vitamin D, which are essential for bone health. When kidney function declines, bones weaken even if a man has no other symptoms. Similarly, men on long-term corticosteroids (for asthma, COPD, or autoimmune disease) lose bone density as a side effect of the medication itself, independent of age.

Rheumatoid arthritis, inflammatory bowel disease, and COPD all increase osteoporosis risk in men, partly because inflammation damages bone and partly because these conditions limit physical activity. A man who is sedentary — whether from arthritis, depression, or straightforward spending most of his day sitting — loses bone density faster than an active man, because bone responds to weight-bearing movement.

When a man should ask for a bone density test

You do not need to wait for a fracture to learn about your bones are thinning. A bone density test, called a DEXA scan, takes about 10 minutes, uses a tiny amount of radiation (less than a chest X-ray), and costs between $100 and $300 depending on where you go. The test measures bone density in your hip, spine, and sometimes forearm, and compares it to a healthy young adult's bones.

Ask your doctor for a DEXA scan if you are a man over 70, or if you are under 70 and have any of these: low testosterone, chronic kidney disease, rheumatoid arthritis, COPD, inflammatory bowel disease, a history of corticosteroid use for more than three months, a personal history of fracture as an adult, or a parent who broke a hip. You should also ask if you have lost height (more than an inch over several years), have a stooped posture, or have had a fall that caused unexpected pain.

If your doctor says a bone density test is not necessary, ask why. If the answer is "you're a man and men don't usually get osteoporosis," that is a reason to seek a second opinion or ask to see a rheumatologist or endocrinologist, who are more likely to take bone health seriously in men.

What the test results mean

A DEXA scan produces a T-score, which compares your bone density to that of a healthy 30-year-old. A T-score of -1.0 or higher is normal. A score between -1.0 and -2.5 means you have low bone density (called osteopenia). A score below -2.5 means you have osteoporosis. Some doctors also look at a Z-score, which compares you to people your age and sex; a Z-score below -2.0 suggests something other than aging is causing bone loss and warrants further investigation.

If your results show low bone density or osteoporosis, your doctor may order additional tests to find the cause: blood work to check testosterone, calcium, vitamin D, and kidney function; sometimes imaging to look for fractures you did not know you had. The cause matters because treatment depends on it. A man with low testosterone may benefit from testosterone replacement (if appropriate for his health), while a man with kidney disease needs different management.

How men can slow or prevent bone loss

Weight-bearing exercise — walking, jogging, climbing stairs, resistance training — is the most important step. Bone responds to stress by building density. Men who are sedentary lose bone faster than men who move. Even modest activity, like a 30-minute walk most days, helps. Resistance training (weights or resistance bands) is especially effective because it places direct stress on bones.

Nutrition matters too. Calcium and vitamin D are the foundation: aim for 1,000 to 1,200 mg of calcium daily (from dairy, leafy greens, fortified foods, or a supplement) and 800 to 1,000 IU of vitamin D daily (from fatty fish, egg yolks, fortified milk, or a supplement). Vitamin D is harder to get from food alone, especially in winter or if you live far north, so many men benefit from a supplement. Ask your doctor to check your vitamin D level; if it is below 20 ng/mL, supplementation is usually recommended.

Limit alcohol (more than two drinks a day increases fracture risk) and do not smoke. If you take corticosteroids long-term, talk to your doctor about whether the dose can be reduced or whether bone-protective medication is appropriate.

Medications for osteoporosis in men

If diet, exercise, and vitamin D are not enough, medications can slow bone loss or build bone density. Bisphosphonates (alendronate, risedronate, zoledronic acid) are the most commonly prescribed. They work by slowing the cells that break down bone. Other options include denosumab (an injection given twice yearly) and teriparatide (a daily injection that actually builds new bone). These medications are used in men the same way they are in women, though they are prescribed less often to men straightforward because men are less likely to be diagnosed in the first place.

If your bone loss is caused by low testosterone, your doctor may discuss testosterone replacement therapy. This is a separate decision from bone-protective medications and depends on your overall health, age, and whether testosterone replacement is appropriate for you. Some men benefit from both approaches.

What happens after a fracture

A fracture from a minor fall or bump — a hip, spine, or wrist break that would not normally happen — is a sign that your bones are weak. After the fracture heals, you should have a bone density test if you have not had one already. Even if you have already been diagnosed with osteoporosis, a fracture means your current treatment is not working well enough and your doctor should reassess your medication or add a second medication.

Recovery from an osteoporosis-related fracture, especially a hip fracture, is long and often incomplete. Many men lose independence, move into assisted living, or do not return to their previous level of activity. That is why finding and treating the disease before a fracture occurs matters so much.

Frequently Asked Questions

Can osteoporosis run in families?

Yes. If your parent, sibling, or grandparent broke a hip or was diagnosed with osteoporosis, your risk is higher. Family history is one of the strongest predictors of bone density. You should mention it to your doctor and ask about bone density testing, especially if you are over 50 or have other risk factors.

Does testosterone replacement prevent osteoporosis?

Testosterone replacement can help maintain or improve bone density in men with low testosterone, but it is not a complete solution and carries its own risks and benefits. Your doctor will weigh whether it is appropriate for you based on your age, health, and the cause of low testosterone. It is not prescribed solely for bone health.

What is the difference between osteoporosis and osteopenia in men?

Osteopenia (T-score between -1.0 and -2.5) means your bones are weaker than normal but not yet at the threshold for osteoporosis (T-score below -2.5). Both increase fracture risk, but osteoporosis carries higher risk. Many men with osteopenia never develop osteoporosis if they exercise, get enough calcium and vitamin D, and avoid smoking and excess alcohol.

Should I take a calcium supplement if I eat dairy?

Not necessarily. If you eat three servings of dairy daily (milk, yogurt, cheese) plus other calcium sources like leafy greens or fortified foods, you may reach 1,000 to 1,200 mg without a supplement. Ask your doctor or a dietitian to review your diet. If you fall short, a supplement fills the gap. Too much calcium from supplements can cause kidney stones, so aim for the right amount, not more.

Can I reverse osteoporosis?

You cannot fully reverse it, but you can slow bone loss and in some cases build back some density with medication, exercise, and good nutrition. The goal is to prevent fractures and maintain independence. Starting treatment early, before severe bone loss occurs, gives you the best outcome.
