Osteoporosis Risk Factors and Early Signs: What to Watch For

Osteoporosis is often called a silent disease because bone loss rarely causes symptoms until a bone breaks. That is why knowing your risk factors matters. Many are outside your control, but others you can change.

Risk Factors You Cannot Change

• Age: bone loss accelerates as we get older.
• Sex: women are at higher risk, especially after menopause.
• Family history: a parent who broke a hip raises your risk.
• Ethnicity: white and Asian women have a higher average risk, though anyone can be affected.
• Small, thin frame: less bone to start with.
• Early menopause: longer exposure to low estrogen.

Risk Factors You Can Influence

• Smoking and heavy alcohol use
• Low calcium or vitamin D intake
• Little physical activity
• Being underweight or losing weight rapidly
• Falls and unsafe home conditions

Our guide to everyday habits that support strong bones covers many of these.

Medical Conditions and Medicines

Some conditions raise risk, including celiac disease, inflammatory bowel disease, rheumatoid arthritis, an overactive thyroid or parathyroid, chronic kidney disease, and type 1 diabetes. Certain medicines can also affect bone, such as long-term oral corticosteroids, some anti-seizure drugs, aromatase inhibitors, and sometimes long-term acid reducers. Never stop a prescribed medicine without talking to your doctor; just make sure your care team knows about your bone risk.

Early Warning Signs

There are usually no symptoms in the early stages, but these signs deserve attention:

• Height loss of about 1.5 inches (4 cm) or more
• Stooped posture or a rounding of the upper back
• Sudden back pain, which can signal a spinal compression fracture
• A fracture from a minor fall or low-level strain, which doctors call a fragility fracture

Brittle nails, receding gums, or weak grip are sometimes mentioned online, but they are not reliable signs on their own.

When to Ask About Testing

Talk with your doctor about a bone density test if you are a woman 65 or older, a man about 70 or older, or younger with risk factors such as early menopause, long-term steroid use, a previous fracture, or a strong family history. Our article on DEXA scans and T-scores explains the results.

What You Can Do Now

1. Get enough calcium and vitamin D.
2. Do weight-bearing, strengthening, and balance exercise.
3. Avoid tobacco and limit alcohol.
4. Make your home safer to prevent falls.
5. Ask your doctor about screening and medicines that affect bone.
