๐ฅ What Is Osteoporosis?
Osteoporosis is a chronic condition where bones become brittle and weak due to loss of density and quality. People over 50, both men and women, are particularly at risk.In Australia, 1 in 2 individuals over 70 experience osteoporosis or osteopenia. Early detection and prevention are crucial to avoid fractures that commonly occur in the spine, hips, and wrists.
⚡️ Major Causes of Osteoporosis
- Aging: Natural bone loss accelerates with age.- Menopause: Hormonal changes speed up bone depletion.
- Lack of Exercise: Weight-bearing activities strengthen bones.
- Calcium & Vitamin D Deficiency: Essential for bone maintenance.
- Smoking & Alcohol: Interfere with calcium absorption.
- Genetic Factors: Family history increases risk.
๐ซ Common Symptoms
Osteoporosis is often called a "silent disease" because symptoms are not obvious until a fracture occurs.You may notice:
- Persistent back pain
- Loss of height
- Easy bone fractures
- Curved or stooped posture
๐ฌ Medicare-Covered DXA Bone Density Test
The DXA (Dual-energy X-ray Absorptiometry) scan is the gold standard for measuring bone density, particularly in the hip and spine.Bone density results are assessed using a T-score:
- -1.0 to -2.5: Osteopenia (low bone mass)
- Below -2.5: Osteoporosis
๐ฐ Eligibility & Frequency for Free Bone Density Tests
Eligible individuals can receive Medicare-funded DXA tests:- Age 70+: Every 5 years (no prior scan required)
- Osteopenia (T-score ≥ -1.5): Every 5 years
- Intermediate Risk (T-score -1.5 to -2.5): Every 2 years
- Diagnosed Osteoporosis (T-score < -2.5): As needed by GP referral
๐ Testing Process
1. Discuss with your GP about your risk profile.2. Receive a referral for a DXA scan.
3. Book and attend a radiology clinic (15–30 min, painless).
4. Review results with GP and start treatment if needed.
๐ Lifestyle Tips for Prevention
- Weight-bearing exercises: walking, stair climbing, resistance training- High calcium diet: dairy, leafy greens, tofu, small fish
- Get Vitamin D: sunlight or supplements
- Avoid smoking and limit alcohol
- Balanced nutrition and regular physical activity
๐ธ For Women in Menopause
Estrogen loss after menopause accelerates bone loss.Consider the following:
- HRT (Hormone Replacement Therapy): Slows bone loss. Discuss with a doctor.
- Calcium intake: 1000–1300mg daily (milk, cheese, yoghurt)
- Vitamin D: Sun exposure or supplements
- Weight training: Walking, resistance bands, light weights
- Regular DXA scans to monitor changes
❗ Who Should Be Extra Cautious?
You are at higher risk if you:- Are 50+ and have experienced a fracture
- Have a family history of osteoporosis
- Take long-term corticosteroids
- Are underweight or malnourished
๐ Treatment After Diagnosis
If diagnosed with osteoporosis, a combination of medical and lifestyle intervention is essential:- GP consultation: Tailor a treatment plan based on risk
- Medications: Bisphosphonates, Denosumab, Teriparatide
- Nutrition: Calcium and Vitamin D supplements
- Exercise: Balance and strength training to prevent falls
- Habits: Stop smoking, reduce alcohol, eat balanced meals
- Follow-up: Regular scans to monitor bone changes
