Osteoporosis
2025-09-22
Intro
Osteoporosis is a disease that weakens bones, making them fragile and more likely to break.
Often called a “silent disease,” it usually shows no symptoms until a fracture occurs.
It affects millions worldwide and is a major cause of disability in older adults.
Key Points
- Osteoporosis = reduced bone density and fragile structure.
- Most common in women after menopause, but also affects men.
- Often detected only after a fracture.
- Diagnosed with bone density scans (DEXA).
- Treatments reduce bone loss and fracture risk; lifestyle measures help prevent progression.
Signs and Symptoms
- Usually no symptoms until a fracture occurs.
- Common fracture sites: hip, spine, wrist.
- Spine fractures may cause height loss, stooped posture, or back pain.
- Hip fractures often lead to loss of mobility and independence.
Causes and Risk Factors
- Hormonal changes: estrogen loss after menopause, low testosterone in men.
- Aging: bone remodeling slows with age.
- Family history: higher risk if a parent had fractures.
- Lifestyle: smoking, alcohol, inactivity, poor diet.
- Medical conditions: rheumatoid arthritis, cancer, thyroid disease.
- Medications: long-term steroids (glucocorticoids).
Diagnosis
- Bone density scan (DEXA): the gold standard test.
- T-score –1.0 to –2.5 = osteopenia (low bone mass).
- T-score ≤ –2.5 = osteoporosis.
- Fracture history: low-impact fractures raise suspicion.
- Blood tests: may be done to rule out other causes.
Treatment
Lifestyle and prevention:
- Weight-bearing exercise: walking, stair climbing, dancing.
- Resistance training: improves bone strength and muscle support.
- Balance and flexibility training: tai chi, yoga — reduce fall risk.
- Adequate calcium and vitamin D intake.
- Avoid smoking and limit alcohol.
- Home safety measures to prevent falls.
Medications:
- Bisphosphonates (alendronate, risedronate, zoledronic acid): most common first-line therapy.
- Denosumab: injection given every 6 months.
- Hormone-related therapies: estrogen therapy or SERMs for some women.
- Anabolic drugs: teriparatide and romosozumab may be used in severe cases to build bone.
Risks and Prognosis
- Fracture risk rises sharply with untreated osteoporosis.
- Hip and spine fractures carry the greatest risk of disability and death.
- With treatment, bone loss can be slowed, fracture risk reduced, and quality of life maintained.
FAQ
Q: Who should get screened?
A: Women over 65, men over 70, and younger people with risk factors or prior fractures.
Q: Can osteoporosis be reversed?
A: Bone density can be improved with some treatments, but full reversal is uncommon. The main goal is reducing fracture risk.
Q: Is it only a women’s disease?
A: No — men are also affected, particularly with age or certain medical conditions.
Q: What’s the difference between osteoporosis and osteopenia?
A: Osteopenia is “low bone mass” (mild bone loss). Osteoporosis is more severe and carries a higher fracture risk.
