Bone Density and Osteoporosis: The Silent Loss Women Need to Track

Osteoporosis affects one in three women and one in twelve men over 50. In India, both dietary calcium and vitamin D deficiency are common, making the underlying risk higher. Yet bone density is rarely tracked systematically until a fracture happens. The specific work of assessment and prevention is straightforward — the challenge is doing it before, not after, the first hip fracture.

The specific risk factors

• Age (biggest single factor).
• Female sex — postmenopausal especially.
• Early menopause (natural or surgical).
• Small body frame.
• Family history of osteoporosis or hip fracture.
• Ethnicity — Asians and Whites higher risk than Africans.
• Prior fracture in adulthood.
• Long-term steroid use.
• Long-term PPI use.
• Some anti-epileptic medications.
• Excessive alcohol, smoking.
• Physical inactivity.
• Dietary calcium deficiency.
• Vitamin D deficiency.
• Certain medical conditions (hyperthyroidism, IBD, celiac, kidney disease).

The DEXA scan — the primary test

• T-score: > -1.0 · Interpretation: Normal · Action: Preventive lifestyle continues
• T-score: -1.0 to -2.5 · Interpretation: Osteopenia (low bone mass) · Action: Prevention emphasis, some patients treated
• T-score: ≤ -2.5 · Interpretation: Osteoporosis · Action: Treatment usually indicated
• T-score: ≤ -2.5 with fracture · Interpretation: Severe osteoporosis · Action: Treatment definitely indicated

When to have a DEXA scan

• All women 65+, all men 70+.
• Postmenopausal women under 65 with risk factors.
• Men 50-70 with risk factors.
• After any adult fracture with minor trauma.
• If on long-term steroids or other bone-affecting medications.
• If chronic conditions affecting bone (rheumatoid arthritis, IBD).
• Baseline at menopause for women with strong risk factors.

Frequency of repeat

• If normal: every 5-10 years unless risk changes.
• If osteopenia: every 2-5 years.
• If on treatment: every 1-2 years initially, then less frequent if stable.
• After any treatment change.

Prevention — the daily habits

• Calcium 1000-1200 mg/day — food first (dairy, leafy greens, fish with bones).
• Vitamin D 800-2000 IU/day — sun + supplement to reach adequate levels.
• Weight-bearing exercise — walking, jogging, hiking.
• Strength training 2-3x per week (specific benefit for bone).
• Balance training — reduces falls (tai chi, yoga).
• Adequate protein — 1-1.2 g/kg/day.
• Avoid smoking, excessive alcohol, excessive caffeine.

Medications when indicated

• Bisphosphonates (alendronate, risedronate, ibandronate, zoledronate) — first line.
• Denosumab — for those who can't tolerate bisphosphonates or with kidney disease.
• Teriparatide — anabolic option for severe osteoporosis.
• Hormone therapy — considered for early menopause with osteoporosis risk.
• SERMs (raloxifene) — for some women.

The fall prevention piece

Osteoporosis matters because fractures happen. Fall prevention is as important as bone density:

• Remove home fall hazards (loose rugs, poor lighting, cluttered paths).
• Assess medications that increase fall risk.
• Vision check annually.
• Hearing check — balance connected.
• Blood pressure with position changes checked.
• Strength and balance exercises.
• Appropriate footwear.

What to record

• DEXA scan results with T-scores at each site (hip, spine, forearm).
• Fracture history.
• Calcium and vitamin D levels.
• Medications affecting bone.
• Treatments started or stopped.
• Height (measure annually — height loss is a subtle sign).
• Any fall or near-fall events.

The specific Indian challenges

• Diet often calcium-deficient — vegetarian without dairy is particularly at risk.
• Vitamin D deficiency near-universal — must be corrected.
• DEXA scanning less widely available than in Western countries.
• Less awareness — often first diagnosis is at hip fracture.
• Cost of medication (bisphosphonates) modest; monitoring more expensive.

Osteoporosis is preventable and treatable. The specific difference between a woman who tracks her bone health from menopause and one who doesn't is often the difference between a productive 70s and a hip fracture that leads to disability. The record makes the difference visible in time to act.
