If you are searching for secondary osteoporosis causes, the short answer is this: it is bone loss that another condition, a medicine or a lifestyle habit drives, not only aging or menopause. Causes named in the sources include hormone problems, long-term inflammatory and gut conditions, certain medicines such as steroids, and smoking or heavy drinking. Knowing which of these might apply to you is the first step toward a plan.
Start with a simple log. Write down when any back pain or ache starts without a clear injury, what you were doing at the time, and every medicine and supplement you take. Bring that list to your clinician, because these details help sort out a cause.
To read any study you come across, the Primary and Secondary Outcomes (our research library) guide shows you how to find which result a study was built to test.
Do calcium and vitamin D change what I should do?
Not on their own. Calcium and vitamin D are part of general bone advice. The NIAMS osteoporosis page, last reviewed December 2022, says a nutritious diet rich in calcium and vitamin D helps maintain good bone health. For secondary osteoporosis, the consumer guide at mdsearchlight.com is more direct: “it’s crucial to identify and treat any underlying health issues that may be contributing to the problem.”
Diet and supplements do not tell you whether your bone loss has a cause that needs treatment. Ask your clinician what calcium and vitamin D intake is right for your case.
What causes secondary osteoporosis?
A 2003 review indexed by PubMed describes secondary osteoporosis as osteoporosis that is “caused or exacerbated by other disorders or medication exposures.” It contrasts this with the bone loss tied to aging and, in women, natural menopause. Mdsearchlight.com groups the causes by type. These are the groups and the examples it names.
| Cause group | Examples named |
|---|---|
| Hormone (endocrine) problems | Primary hyperparathyroidism, Cushing’s syndrome, hyperthyroidism, early menopause (premature ovarian insufficiency), diabetes |
| Chronic inflammatory conditions | Rheumatoid arthritis, cystic fibrosis, COPD, chronic kidney disease |
| Gut and liver conditions | Inflammatory bowel disease, celiac disease, chronic liver disease |
| Nutrition | Anorexia nervosa, a history of bariatric (weight-loss) surgery |
| Medicines | Glucocorticoid steroids and some cancer medicines (NIAMS); glucocorticoid-induced osteoporosis (mdsearchlight.com) |
| Lifestyle | Smoking, heavy drinking, and long periods of inactivity (NIAMS) |
| Other | Neuromuscular diseases, HIV, post-transplant bone loss, genetic conditions such as thalassemia and Ehlers-Danlos syndrome |
Doctors also look at conditions that can mimic osteoporosis. Mdsearchlight.com lists osteomalacia, Paget’s disease and multiple myeloma among them. The 2003 review on PubMed says these secondary causes are “frequent in cases initially labelled as primary osteoporosis.”
Which factors raise the risk of osteoporosis in women?
The womenshealth.gov osteoporosis page, updated April 28, 2026, lists these risk factors for women:
- Being past menopause. After menopause, the ovaries make very little estrogen, and some women lose up to 25% of bone mass in the first 10 years.
- A small, thin body (weighing less than 127 pounds).
- A family history of osteoporosis.
- Not getting enough calcium and vitamin D, or not enough physical activity.
- Not having 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.
- An eating disorder, especially anorexia nervosa and bulimia nervosa.
- Smoking.
- Health problems such as diabetes, premature ovarian failure, celiac disease, inflammatory bowel disease and depression.
- Medicines for long-term problems such as arthritis, asthma, lupus or thyroid disease.
- Drinking too much alcohol. For women, one drink a day at most.
Womenshealth.gov also says Mexican-American and white women are at higher risk, and that Asian-American women have a higher risk because they are usually smaller and thinner. Hispanic and African American women are at lower risk but still at significant risk, according to NIAMS.
What are 5 symptoms of osteoporosis?
Osteoporosis is often called a “silent” disease because there are typically no symptoms until a bone breaks. The NIAMS page lists these signs, most often from a spine fracture:
- Back pain
- Loss of height
- A hunched or stooped posture (kyphosis)
- A curve in the back
- Sloping shoulders
The fractures themselves can come from a minor fall, from a fall from standing height, or from normal stresses such as bending, lifting or even coughing. If you notice any of these changes, bring them to your clinician.
How is secondary osteoporosis diagnosed?
Doctors usually start with a DXA bone density scan. DXA (dual-energy X-ray absorptiometry) is an X-ray test that measures how dense your bones are. Mdsearchlight.com says a T-score of -2.5 or less on a DXA scan 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 also counts. Spine x-rays may be taken if a fracture is suspected.
The step to check for a secondary cause comes next. 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 research topic on secondary causes of bone fragility, as of November 2026, lists the signs that should raise suspicion: a clinical sign of a specific disease, a Z-score more than -2 SD, a very low T-score compared with fracture risk factors, a fragility fracture with normal or osteopenic bone density (osteopenia means bone density that is lower than normal), or treatment that does not work despite adequate adherence.
The tests that can follow, according to mdsearchlight.com, include blood count tests, inflammatory condition checks, bone, kidney and liver function checks, diabetes evaluation, hormone level tests and thyroid checks. A bone biopsy is used in some severe cases. The full list depends on your symptoms and history. Mdsearchlight.com says you should see a primary care physician or a bone health specialist such as an endocrinologist or rheumatologist.
On cost, the womenshealth.gov osteoporosis page, updated April 28, 2026, says that if you have Medicare, you should find out about Medicare coverage for bone density tests. If you have no insurance, you may be able to get a no-cost or low-cost bone density test. Check with your insurance provider to see what your plan includes.
Can taking too much vitamin D3 cause osteoporosis?
Womenshealth.gov says vitamin D helps your body absorb calcium from the food you eat. Whether too much vitamin D3 can affect your bones is a question for your clinician, who can look at your intake, your history and any supplement you already take. Ask before you start or raise a vitamin D3 supplement.
Is there one vitamin that rebuilds bone density?
What it says is, “Calcium and vitamin D work together to build and maintain strong bones.” Food sources of calcium named on the pages include milk, cheese, yogurt and leafy greens such as broccoli, kale and mustard greens. Vitamin D foods named include salmon, tuna and egg yolks. Womenshealth.gov advises you to talk with your doctor or nurse before taking calcium supplements to see which kind and how much is right for you.
What drink makes bones stronger?
The womenshealth.gov page names milk, calcium-fortified orange juice and soymilk as sources of calcium, which helps build bones. 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.
Which foods should I avoid if I have osteoporosis?
The habits it names as harmful are smoking and heavy drinking. For food, it points you toward calcium-rich choices such as milk, cheese, yogurt and leafy greens. Ask your clinician about any specific food concerns for your case.
What exercises help with osteopenia?
If you have been told you have osteopenia, the activity advice on the womenshealth.gov page is useful to know. It says women of all ages need regular weight-bearing physical activity to build and maintain bone density. Weight-bearing means your body works against gravity. The examples it names are dancing, gardening, lifting weights, tennis, tai chi, yoga, running and walking.
Balance matters too, because fractures often come from falls. The NIA’s room-by-room fall prevention guide covers how to lower fall risk at home. For a wider look at joint, muscle and bone care, see Joint, Muscle and Bone Care. Ask your clinician which of these fit your bones and your balance before you start.
What are the guidelines for preventing osteoporosis?
The NIAMS page and the womenshealth.gov page agree on the core steps:
- Get enough calcium and vitamin D each day, mainly from food.
- Stay physically active, with weight-bearing activity such as walking.
- Do not smoke, or do not start.
- Drink alcohol in moderation. For women, one drink a day at most.
- Take prescribed medicines, which NIAMS says can help prevent fractures in people who have osteoporosis.
- Build bone early. Womenshealth.gov says building strong bones in childhood and the teen years helps prevent osteoporosis later.
- Ask your doctor whether you need medicine to prevent bone loss.
Can you work with osteoporosis?
The NIAMS and womenshealth.gov pages focus on fractures rather than work. Womenshealth.gov says a broken bone can cause severe pain and disability and can make everyday tasks, such as walking, harder. Untreated osteoporosis can lead to serious breaks, especially in the hip and spine. Whether your job suits you depends on your bone health, your fracture risk and any treatment you take. Bring a description of your job’s physical demands to your clinician.
What are the treatment options, and what is still being studied?
Treatment starts with the cause. Mdsearchlight.com says that until underlying conditions are addressed, it may be hard to get the full benefit of standard osteoporosis treatments. The options the pages describe are below.
| Option | What the pages say it does | When it is used, or what to know |
|---|---|---|
| Treating the underlying condition | Mdsearchlight.com says endocrine-related osteoporosis can often be managed by treating the underlying disease | Mdsearchlight.com says it may be hard to get the full benefit of standard treatments until underlying conditions are addressed. Your clinician decides the order. |
| Bisphosphonates | Womenshealth.gov says they help treat bone loss and may help build bone mass | Mdsearchlight.com lists them among antiresorptive agents |
| Denosumab | An injectable 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 for broken bones from osteoporosis |
| Selective estrogen receptor modulators (SERMs) | Womenshealth.gov says they may help slow the rate of bone loss after menopause | Used after menopause |
| Calcitonin | Womenshealth.gov describes it as a hormone made by the thyroid gland that helps regulate calcium levels and build bone mass | Womenshealth.gov says taking it can help slow the rate of bone loss |
| Menopausal hormone therapy | Often used for menopause symptoms; womenshealth.gov says it may also help prevent bone loss | Womenshealth.gov says it may raise the risk of blood clot, heart attack, stroke, breast cancer or gallbladder disease |
| Teriparatide | An injectable 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 patients who have not responded well to other treatments |
| Abaloparatide | An anabolic agent that stimulates new bone formation (mdsearchlight.com) | Same use as teriparatide, according to mdsearchlight.com |
Womenshealth.gov says all medicines have risks, so talk to your doctor or nurse about the benefits and risks of any option before you decide. The NIA’s guide to taking medicines safely, last reviewed September 2022, says not to stop a prescription drug unless your doctor says it is okay. For a fuller walk through the options and their side effects, see Osteoporosis treatment 2026.
What is still under study? The Frontiers research topic, as of November 2026, says that secondary causes of bone fragility “are still poorly understood and insufficiently addressed in standard clinical practice.” Its stated aims include advances in the assessment and treatment of secondary bone fragility.
Which option fits depends on the cause, your fracture risk and your history. That is a decision for you and your clinician to make together.
What will treatment and testing cost, and how do I check?
Prices change, and they depend on your plan. Check the price of any test or medicine with your insurer or clinic.
- Medicare: womenshealth.gov says to find out about Medicare coverage for bone density tests.
- Medicaid: womenshealth.gov says the covered 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, and points you to a health center finder by ZIP code.
- Medicines: the NIA guide says a generic drug is just as safe, and is of equal strength and quality, as a brand-name drug. It also says people with financial hardship who receive Medicare drug benefits may qualify for the Medicare Extra Help Program.
What should I ask at my appointment?
- 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?
