Osteoporosis 101
- Bone Density Peak: Ladies, your bones hit their strongest at 19 years old!
- Bones Get Weaker Over Time: Especially after menopause, making them more fragile and prone to fractures.
T-Score vs. Z-Score
- T-Score: Compares your bone strength to a healthy 30-35 y/o woman. Used if you’re 40+ years old.
- Z-Score: Compares your bones to people your own age. Used if you’re under 40. If it’s less than -2, more tests are needed!
Who’s at Risk for Fractures?
Biggest Risk Factors:
Age (older = higher risk)
History of a Fragility Fracture (like breaking a bone from a small fall)
Low Bone Density (BMD)
Other Risk Factors:
Smoking, too much alcohol, long-term steroid use, low weight, rheumatoid arthritis, early menopause, and family history of hip fractures.
FRAX – Fracture Risk Calculator
This tool predicts your 10-year fracture risk based on your age, weight, medical history, and lifestyle.
- Treatment needed if:
- Hip fracture risk > 3%
- Major fracture risk > 20%
- Who should use FRAX? Women 40+ who are postmenopausal and not already on osteoporosis treatment.
BMD Testing – When to Get a DEXA Scan?
All women 65+ should get a DEXA scan!
If < 65, get a scan if you have risk factors like:
- Low weight (<127 lbs)
- Fragility fracture history
- Family history of hip fractures
- Smoking, heavy alcohol use, RA, or medical conditions that weaken bones
Bone Mineral Density (BMD) Categories
- Normal Bone Density: T-score above -1 → Repeat scan in 15 years
- Osteopenia (Mild Bone Loss): T-score -1 to -2.49
- Repeat scan in 5 years (if -1.5 to -1.99)
- Repeat in 1 year (if -2 to -2.49)
- Osteoporosis (Severe Bone Loss): T-score below -2.5
- Repeat scan in 2 years after starting treatment
How to Keep Bones Strong?
- Calcium & Vitamin D: Keep those bones strong!
- Calcium Needs:
- 1,300mg/day (age 9-18)
- 1,000mg/day (age 19-50, pregnancy, lactation)
- 1,200mg/day (age 51+)
- Vitamin D Needs:
- 600 IU/day (under 70)
- 800 IU/day (over 70)
- Upper safe limit: 4,000 IU/day
- Calcium Needs:
- Exercise: Weight-bearing and strength training!
- Quit smoking & limit alcohol
- Fall-proof your home: Secure rugs, install grab bars, and keep floors clutter-free
Osteoporosis Medications
- First-Line Treatment: Bisphosphonates (-dronate drugs like Alendronate, Zoledronic acid)
- Reduce bone breakdown
- Take on an empty stomach, stay upright for 30 min (to avoid stomach issues)
Other Medications:
- SERMs (Raloxifene): Protects bones, also reduces breast cancer risk, but increases clot risk
- Denosumab (Prolia): Given if high fracture risk or can’t take bisphosphonates
- Anabolic Agents (-paratide drugs like Teriparatide): Build new bone, used for severe cases
- Romosozumab: A newer option for severe osteoporosis
Takeaways!
- Get a DEXA scan at 65+ (or earlier if high risk)
- Prevent fractures with diet, exercise, and fall-proofing
- If needed, treat with meds to strengthen bones
- Know your FRAX score & risk factors!
STRONG BONES, STRONG LIFE!
