Secondary osteoporosis is bone loss that has a driver besides aging or menopause: another health condition, a medicine, or a habit such as smoking or heavy drinking. If you have been told you have osteoporosis, or a bone broke after a minor fall, finding that driver is the step that shapes the rest of your plan.

What causes secondary osteoporosis?
A 2003 review on PubMed defines secondary osteoporosis as osteoporosis “caused or exacerbated by other disorders or medication exposures.” That sets it apart from the bone loss tied to aging and, in women, natural menopause. Here is how we group the causes, combining what NIAMS and mdsearchlight.com name. Many people with osteoporosis have more than one of these. NIAMS notes that some people with osteoporosis have no specific risk factors at all.
| Cause group | Examples named |
|---|---|
| Hormone (endocrine) problems | Primary hyperparathyroidism, Cushing’s syndrome, hyperthyroidism, early menopause (premature ovarian insufficiency, loss of ovarian function before 40), type 1 and type 2 diabetes |
| Chronic inflammatory and kidney conditions | Rheumatoid arthritis, cystic fibrosis, COPD (mdsearchlight.com says about one in three people with COPD have osteoporosis), chronic kidney disease, idiopathic hypercalciuria (high calcium in the urine) |
| Gut and liver conditions | Inflammatory bowel disease, celiac disease, chronic liver disease |
| Nutrition and weight-loss surgery | Anorexia nervosa, a history of bariatric (weight-loss) surgery, excessive dieting or poor protein intake (NIAMS) |
| Medicines | Long-term glucocorticoid steroids, antiepileptic medicines, some cancer medicines that use hormones, proton pump inhibitors (stomach acid reducers), selective serotonin reuptake inhibitors (antidepressants), thiazolidinediones (a diabetes medicine class) |
| Lifestyle | Smoking, chronic heavy drinking, long periods of inactivity |
| Nervous system and muscle | Multiple sclerosis (mdsearchlight.com says twice as likely to have osteoporosis), Parkinson’s disease, bone loss after stroke, cerebral palsy, spina bifida, Duchenne muscular dystrophy |
| Other | HIV and its therapy, post-transplant bone loss, genetic conditions such as thalassemia and Ehlers-Danlos syndrome |
Conditions that can look like osteoporosis
Before a secondary cause is named, doctors also consider conditions that weaken bone in similar ways. Mdsearchlight.com lists these:
- Osteomalacia, softening of the bones
- Renal osteodystrophy, a bone disorder linked to kidney disease
- Paget’s disease, a bone disorder that usually appears in older adults
- Multiple myeloma, a cancer of plasma cells
- Lymphoma, a type of cancer
- Mastocytosis, overproduction of mast cells
- Sickle cell anemia, a blood disorder
- Osteonecrosis, loss of blood flow to the bone
- Bone infections
- Homocystinuria, an inherited disorder affecting how the body processes the amino acid methionine
- Scurvy, a disease caused by a lack of vitamin C
- Homocysteinemia, high levels of homocysteine in the blood
- Metastatic bone disease, cancer that has spread to the bones
A 2003 review from a Spanish health-system journal, indexed on PubMed, says these secondary causes are “frequent in cases initially labelled as primary osteoporosis.” That is why it is worth checking for a cause even when the picture seems simple.
How does a cause lead to bone loss?
Your bones are rebuilt all your life. NIAMS says osteoporosis develops when bone mass and bone mineral density drop, or when the structure of bone changes. Womenshealth.gov describes the usual pattern: as you age, your bones don’t make new bone fast enough to keep up with your body’s needs, and bone loss speeds up after menopause.
Secondary causes take other routes. The Frontiers research topic on secondary causes of bone fragility lists altered mineral metabolism, hormone imbalance, impaired bone remodeling (the normal cycle of breaking down and rebuilding bone) and chronic low-grade inflammation. Mdsearchlight.com gives examples: in Cushing’s syndrome, bone breakdown increases and bone formation drops, and after a stroke, bone is lost through immobilization and neurologic disability.
Your starting point matters too. Womenshealth.gov says girls develop 90% of their bone mass by age 18, so anything that blocks that build-up leaves less bone to draw on later. Mdsearchlight.com says some medicines and conditions stop full bone mass from forming in young adulthood, or cause excessive loss later.
Which factors raise the risk of osteoporosis in women?
Womenshealth.gov says your risk is higher if you:
- Are past menopause. Some women lose up to 25% of bone mass in the first 10 years after it.
- Weigh less than 127 pounds.
- Have a family history of osteoporosis.
- Are Mexican-American or white. Asian-American women also have a higher risk, because they are usually smaller and thinner.
- Do not get enough calcium and vitamin D, or enough physical activity.
- Have not had a period for three months in a row, if you are not pregnant, breastfeeding or taking a medicine that stops periods. Talk to your doctor or nurse about this.
- Have an eating disorder, especially anorexia nervosa or bulimia nervosa.
- Smoke. The risk of broken bones goes up the longer and more you smoke.
- Have a health problem such as diabetes, premature ovarian failure, celiac disease, inflammatory bowel disease or depression.
- Take certain medicines for long-term problems such as arthritis, asthma, lupus or thyroid disease.
- Drink too much alcohol. For women, one drink a day at most.
NIAMS adds that African American and Hispanic women have a lower risk but are still at significant risk. Men are at risk too, especially after age 70.
How common is secondary osteoporosis?
Mdsearchlight.com says additional factors that cause secondary osteoporosis are present in about 30% of postmenopausal women and 50% to 80% of men. For osteoporosis overall, womenshealth.gov says about 10 million Americans have it, and more than 80% of them are women. It also says one in four women 65 or older in the United States has it. Mdsearchlight.com gives a higher US estimate of 20 to 25 million people, and about two million fractures a year. Treat the numbers as estimates.
What are the symptoms, and how do I track them?
Osteoporosis is often called a “silent” disease, because you typically have no symptoms until a bone breaks. When signs do show up, they usually come from a spine fracture. NIAMS and womenshealth.gov list these five:
- Back pain
- Loss of height
- A hunched or stooped posture (kyphosis)
- A curve in the back
- Sloping shoulders
Fractures can come from a minor fall, such as a fall from standing height, or from normal stresses like bending, lifting or even coughing (NIAMS). Womenshealth.gov notes that spine fractures can happen during everyday activities such as climbing stairs, lifting objects, or bending forward.
Because the early signs are quiet, a simple log helps you see a pattern. Write down:
- When any back ache starts, with the date and the time of day.
- What you were doing: bending, lifting, coughing, climbing stairs, or a fall.
- Any change in your height or posture, measured the same way each time.
- Any bone break, and whether it followed a minor fall.
- Every medicine and supplement you took that week.
Bring the log to your appointment. It gives your clinician the details that a cause search depends on.
How do doctors check for a secondary cause?
The first test is usually a DXA scan. DXA (dual-energy X-ray absorptiometry) is an X-ray of your bones that measures density, using a very low amount of radiation (womenshealth.gov). Mdsearchlight.com says a T-score of -2.5 or less can diagnose osteoporosis. A T-score compares your bone density with that of a healthy 30-year-old adult. A fracture after a minor injury can also lead to a diagnosis. Spine X-rays may be taken if a fracture is suspected.
Womenshealth.gov says your doctor may suggest a bone density test if you are 65 or older, or younger than 65 with risk factors.
The next step is looking for a secondary cause. Mdsearchlight.com says doctors may look for one in a premenopausal woman with osteoporosis, or in a man under 50 with weak bones or fractures. The Frontiers topic lists the signs that should raise suspicion:
- A clinical sign of a specific disease
- A Z-score (a bone density score compared with people your age and sex) of more than -2 SD
- A very low T-score compared with your fracture risk factors
- A fragility fracture (a break from a minor fall) with normal or osteopenic bone density
- Osteoporosis or a fracture in people with normal sex hormone levels (eugonadal)
- Treatment that is not working despite taking it as prescribed
Other tools add detail. Mdsearchlight.com describes FRAX, which estimates your risk of a major fracture in the next 10 years, but notes it may be less useful under 40 or with worse spinal bone density. The trabecular bone score looks at bone structure, HRpQCT looks at the small-scale structure of bone, and a bone biopsy (a small sample of bone tissue) is sometimes used in severe cases. Mdsearchlight.com notes that some people break bones despite normal bone mass, which can happen with diabetes.
Depending on your symptoms and history, the tests that follow can include blood counts, checks for inflammatory conditions, bone, kidney and liver function, a diabetes evaluation, hormone levels and thyroid checks. Mdsearchlight.com says the full list depends on your case. It names a primary care physician, or a bone specialist such as an endocrinologist or rheumatologist, as the right doctor to start with.
What is osteopenia, and what exercise helps?
Osteopenia means your bone density is lower than normal. If you have been told you have it, the activity guidance from womenshealth.gov is the most useful place to start. Regular physical activity of any type helps slow bone loss, improve muscle strength and help your balance. Weight-bearing activity matters most, because your body works against gravity during it. The examples the page lists are:
- Dancing
- Gardening
- Lifting weights
- Tennis
- Tai chi
- Yoga
- Running
- Walking
Balance matters too, because many fractures come from falls. Womenshealth.gov says fractures can follow a minor stumble or a bump into furniture. The NIA room-by-room fall prevention guide lists the home changes that lower the risk: handrails on both sides of stairs, good lighting with switches at the top and bottom, grab bars by the toilet and in the tub or shower, nonskid mats on wet surfaces, no throw rugs, and a night light in the bathroom.
For joint, muscle and bone care more broadly, see Joint, Muscle and Bone Care.
What are the guidelines for preventing osteoporosis?
NIAMS says you can take steps to help prevent the disease and fractures. Its guidance and the womenshealth.gov guidance agree on these core steps:
- Get enough calcium and vitamin D every day, mainly from food.
- Stay physically active, choosing weight-bearing activity such as walking, running or dancing.
- Do not smoke, or do not start.
- Drink alcohol in moderation. For women, that is one drink a day at most. Too much at one time, or mixed with certain medicines, can affect your balance and lead to falls.
- Take prescribed medicines. NIAMS says they can help prevent fractures in people who have osteoporosis.
- Build strong bones early. Womenshealth.gov says building them in childhood and the teen years helps prevent osteoporosis later.
What should I eat and drink for stronger bones?
Womenshealth.gov gives these daily amounts for women:
- Calcium: 1,300 mg at ages 9 to 18; 1,000 mg at 19 to 50; 1,200 mg at 51 and older.
- Vitamin D: 600 IU up to age 70; 800 IU at 71 and older.
- Pregnant or nursing women need the same amounts as other women of the same age.
Calcium occurs naturally in milk, cheese, yogurt and leafy greens such as broccoli, kale and mustard greens. Some breakfast cereals, orange juice, tofu, soymilk, breads and pastas have calcium added. If dairy upsets you, womenshealth.gov suggests lactose-reduced milk or yogurt, a lactose supplement taken before dairy, or other calcium sources.
Vitamin D is found in salmon, tuna and egg yolks, and it is added to some cereals, milk and orange juice. Your skin also makes vitamin D in sunlight. Womenshealth.gov says about 10 to 15 minutes of sun on your hands, arms and face, two to three times a week, is generally enough, though it depends on your skin, sunscreen use, season, location and air pollution.
Is there one vitamin that rebuilds bone density?
Womenshealth.gov says calcium and vitamin D work together to build and maintain strong bones, and that vitamin D helps your body absorb the calcium you eat. Mdsearchlight.com says getting enough calcium and vitamin D can help strengthen bones. Womenshealth.gov also says it is best to get calcium from food, and that a calcium supplement may be worth considering if food does not provide enough.
What drink makes your bones stronger?
Womenshealth.gov names milk as a natural source of calcium, and calcium-fortified orange juice and soymilk as added sources. It also says long-term, heavy drinking can cause bone loss, and that for women, one drink a day is the most you should have.
Can taking too much vitamin D3 cause osteoporosis?
Womenshealth.gov gives the recommended amounts for women: 600 IU a day up to age 70, and 800 IU a day from age 71. Those are the amounts it recommends. Tell your doctor or pharmacist about every vitamin D3 supplement you take. The NIA’s guide to taking medicines safely says to mention every vitamin, supplement and herbal remedy at each visit, because mixing them with other medicines can cause problems.
Which foods should I avoid if I have osteoporosis?
Womenshealth.gov names habits that harm bone: smoking, and heavy drinking. NIAMS adds that a diet low in calcium and vitamin D can raise your risk, and that excessive dieting or poor protein intake may increase bone loss. The practical focus is getting enough calcium, vitamin D and protein, and cutting back on the habits above.
Can you work with osteoporosis?
Womenshealth.gov says a broken bone can cause severe pain and disability, and can make everyday tasks such as walking harder. It also says a spine fracture can happen during ordinary tasks like climbing stairs, lifting objects or bending forward. Whether your job suits you depends on your bone density results, your fracture risk and any treatment you take. Write down the lifting, bending and stair-climbing parts of your workday so you can go over them at your appointment.
What are the treatment options for secondary osteoporosis?
Treatment starts with the cause. Mdsearchlight.com says that until underlying conditions are addressed, you may not get the full benefit of standard osteoporosis treatments. For osteoporosis linked to hormone disorders, it says the problem can often be managed by addressing the underlying disease. The options named across NIAMS, womenshealth.gov and mdsearchlight.com are below.
| Option | What it is said to do | When it is used, or what to know |
|---|---|---|
| Addressing the underlying condition | Mdsearchlight.com says osteoporosis from endocrine disorders can often be managed by addressing the underlying disease | Mdsearchlight.com says the full benefit of standard treatment may be hard to get until these conditions are addressed. Your clinician sets the order. |
| Bisphosphonates | Womenshealth.gov says they help with bone loss and may help build bone mass | Mdsearchlight.com lists them among antiresorptive agents, which slow the breakdown of bone |
| Denosumab | An injected drug that womenshealth.gov says may help reduce bone loss and improve bone strength | Womenshealth.gov says it may be used if you are past menopause and at higher risk of broken bones. Mdsearchlight.com says it is also effective for patients with kidney problems, because it does not need the kidneys to clear it from the body. |
| Selective estrogen receptor modulators (SERMs) | Womenshealth.gov says they may help slow bone loss after menopause | Used after menopause |
| Calcitonin | A hormone made by the thyroid gland that helps regulate calcium levels. Womenshealth.gov says taking it can help slow bone loss. | Womenshealth.gov lists it among the options |
| Menopausal hormone therapy | Often used for menopause symptoms. Womenshealth.gov says it may also help prevent bone loss. | Womenshealth.gov says the FDA recommends the lowest dose that works for menopause symptoms, for the shortest time needed. It may raise the risk of blood clot, heart attack, stroke, breast cancer or gallbladder disease. |
| Teriparatide | An injected form of human parathyroid hormone that helps the body build new bone faster than old bone is broken down (womenshealth.gov) | Mdsearchlight.com says it is typically used in severe cases, or in people who have not responded well to other treatments |
| Abaloparatide | An anabolic agent (a medicine that stimulates new bone formation), according to mdsearchlight.com | Mdsearchlight.com says it has the same use as teriparatide |
Womenshealth.gov says your doctor may also suggest more calcium, vitamin D and physical activity. It says all medicines have risks, and gives menopausal hormone therapy as its example. The NIA’s guide to taking medicines safely adds that you should not stop a prescription medicine unless your doctor says it is okay, and that some medicines need to be stopped slowly.

What do the Japanese take for osteoporosis?
Most of the guidance on this page comes from US health agencies, so it cannot tell you what is typical in Japan. The options in the table are the ones the NIAMS, womenshealth.gov and mdsearchlight.com pages name.
What is still being studied?
The Frontiers topic says secondary causes of bone fragility “are still poorly understood and insufficiently addressed in standard clinical practice.” Its stated aims include better tools to tell secondary from primary bone fragility, and treatments tailored to specific conditions. It describes a research collection on this subject rather than a single study.
What will testing and treatment cost?
Prices change and depend on your plan, so check the cost of any test or medicine with your insurer, clinic or pharmacy before you go. The public guidance says:
- Screening: womenshealth.gov says osteoporosis screening is covered by most insurance plans, including Medicare Part B, and depending on your plan you may be able to get it at no cost.
- Medicare: womenshealth.gov says to find out about Medicare coverage for bone density tests.
- Medicaid: benefits differ by state, so check with your state’s Medicaid program.
- No insurance: womenshealth.gov says you may be able to get a no-cost or low-cost bone density test. Its health center finder searches by ZIP code, and HealthCare.gov shows whether you qualify for low-cost coverage.
- Medicines: the NIA guide says a generic drug is just as safe, and of equal strength and quality, as its brand-name version. People with financial hardship who receive Medicare drug benefits may qualify for the Medicare Extra Help Program.
What should I ask at my appointment?
Bring your symptom log and any DXA results you already have. Then ask:
- Could my bone loss have a secondary cause, and which tests check for it?
- What do my DXA results mean, including my T-score?
- Which of my current medicines, conditions or habits might affect my bones?
- Is my calcium and vitamin D intake right for me, and do I need a supplement?
- Which activities are safe for my bones and my balance?
- Which treatment options fit my cause, and what are their risks?
- Should I see a primary care physician, an endocrinologist or a rheumatologist?
Take this list and your log to your clinician.
Your next step
Start the symptom log this week. Note any back ache, height change or bone break with the time of day and what you were doing. Check the causes table for anything that matches your history. Bring both to your appointment. When you are ready to compare the drug options, read Osteoporosis treatment 2026: options, costs, side effects.
