Osteoporosis: Causes, Symptoms & Treatment
Osteoporosis is a bone disease characterized by reduced bone mass and deterioration of bone structure, making bones weak, fragile, and more prone to fractures. It develops when bone breakdown occurs faster than new bone formation.
What is Osteoporosis?
Healthy bones continuously undergo a natural process called bone remodeling, where old bone is absorbed and new bone is formed. Osteoporosis occurs when bone loss exceeds bone formation, resulting in decreased bone density and increased fracture risk.
It is often called the "Silent Disease" because bone loss occurs gradually without noticeable symptoms until a fracture happens.
Low Bone Density
Bones become thinner, weaker, and more fragile over time.
Higher Fracture Risk
Even minor falls or injuries can result in fractures.
Silent Progression
Most people have no symptoms until a fracture occurs.
Common in Elderly
Particularly affects postmenopausal women and older adults.
Signs & Symptoms of Osteoporosis
- No symptoms in early stages
- Sudden fractures after minor falls
- Persistent back pain
- Loss of height over time
- Stooped posture or spinal deformity
- Compression fractures of the spine
- Fragility fractures of hip, wrist, or spine
Risk Factors for Osteoporosis
Several lifestyle, genetic, hormonal, and medical factors can increase the likelihood of developing osteoporosis.
Postmenopausal Women
Reduced estrogen levels accelerate bone loss.
Family History
Genetics play an important role in bone health.
Smoking & Alcohol
Both significantly weaken bone quality over time.
Vitamin D Deficiency
Poor calcium absorption contributes to weaker bones.
Additional Risk Factors
- Asian and Caucasian ethnicity
- Small body frame
- Eating disorders
- Excess caffeine consumption
- Physical inactivity
- Thyroid disorders
- Long-term steroid use
Bone Density Test (DEXA Scan)
A DEXA Scan is the most accurate and widely used test to measure bone mineral density and diagnose osteoporosis.
The test is painless, non-invasive, and usually takes only 10–20 minutes to complete.
Early Detection
Identifies bone loss before fractures occur.
Quick & Painless
Non-invasive scan with minimal radiation exposure.
Recommended for Women 65+
Particularly important for postmenopausal women.
Fracture Risk Assessment
Helps guide treatment decisions and prevention strategies.
Best Sources of Calcium
- Milk and dairy products
- Yogurt and cheese
- Eggs
- Ragi (Finger Millet)
- Fish and seafood
- Almonds
- Spinach and Fenugreek Leaves
- Bananas
Exercise for Osteoporosis Prevention
Regular exercise stimulates bone remodeling and helps maintain bone strength. Weight-bearing and resistance exercises are particularly beneficial.
Walking
One of the safest and most effective weight-bearing exercises.
Weight Training
Helps strengthen bones and improve muscle mass.
Cycling
Improves fitness and supports joint health.
Cross Training
Enhances balance, coordination, and bone strength.
Medications Used in Osteoporosis
- Bisphosphonates (Alendronate, Risedronate)
- Selective Estrogen Receptor Modulators (SERMs)
- Calcitonin
- Teriparatide (Bone Forming Therapy)
- Vitamin D Supplements
- Calcium Supplements
- Hormone Replacement Therapy (Selected Cases)
Preventing Osteoporosis
Early diagnosis and appropriate treatment can significantly reduce the risk of fractures and improve long-term bone health. If you are at risk for osteoporosis, consult your orthopedic specialist for screening and preventive care.
