Osteoporosis
Osteoporosis is a systemic skeletal disease characterized by a reduction in bone mineral density (BMD) and deterioration of the microarchitecture of bone tissue, leading to increased bone fragility and fracture risk. It is defined by the WHO as “a disease in which bones become fragile and more prone to fractures.”
Osteoporosis is one of the most widespread chronic diseases globally: it affects approximately 200 million people, with over 5 million in Italy alone. After the age of 50, one in three women and one in five men will experience a fragility fracture during their lifetime. The most frequent osteoporotic fractures — vertebral, hip, and wrist (wrist fractures) — represent one of the main causes of disability, loss of autonomy, and mortality in the elderly population.
The good news is that osteoporosis is preventable and treatable. Physical exercise — particularly muscle strengthening and weight-bearing exercises — is one of the fundamental pillars of both prevention and treatment, alongside pharmacological therapy and adequate nutrition.

What is Osteoporosis?
Bone Tissue: A Living Tissue
Bone is not a static structure but a living tissue in continuous remodeling. Two types of cells work constantly:
- Osteoblasts: build new bone (bone formation)
- Osteoclasts: resorb old bone (bone resorption)
Under normal conditions, there is a balance between formation and resorption. In osteoporosis, resorption exceeds formation, and bone progressively loses mass and quality.
Classification
- Primary Osteoporosis Type I (post-menopausal): caused by the drop in estrogen after menopause. Primarily affects trabecular bone (vertebrae, wrist)
- Primary Osteoporosis Type II (senile): linked to aging (>70 years). Affects both trabecular and cortical bone (femur, vertebrae)
- Secondary Osteoporosis: caused by medications (corticosteroids), diseases (hyperthyroidism, celiac disease, rheumatoid arthritis), lifestyle (inactivity, malnutrition)
Densitometric Diagnosis (DEXA)
The diagnosis of osteoporosis is based on bone densitometry (DEXA), which measures bone mineral density and expresses it as a T-score:
| T-score | Condition |
|---|---|
| > -1.0 | Normal |
| -1.0 to -2.5 | Osteopenia (reduced density) |
| < -2.5 | Osteoporosis |
| < -2.5 + fracture | Severe Osteoporosis (established) |
Risk Factors
Non-Modifiable
- Age: risk progressively increases with aging
- Female sex: women have a 4 times higher risk than men (effect of menopause)
- Early menopause (< 45 years): premature loss of estrogen protection
- Caucasian or Asian ethnicity: higher risk
- Family history: history of hip fractures in parents
- Low body weight: BMI < 19
Modifiable (on which to intervene)
- Sedentary lifestyle: the most important modifiable factor. Inactivity reduces mechanical stimulation on the bone, accelerating bone mass loss
- Low calcium and vitamin D intake: frequent nutritional deficiencies, especially in the elderly
- Smoking: reduces bone density and increases fracture risk by 40-60%
- Excessive alcohol: more than 2-3 units per day
- Medications: corticosteroids (the most frequent pharmacological cause), anticonvulsants, long-term proton pump inhibitors
- Falls: factors that increase the risk of falling (muscle weakness, balance disorders, orthostatic hypotension, sedative medications) indirectly increase fracture risk
Symptoms
Silent Osteoporosis
Osteoporosis is defined as a “silent disease” because it causes no symptoms until the first fracture. There is no pain, swelling, or functional limitation during the bone loss phase. Many patients discover they have osteoporosis only after a fracture.
Fragility Fractures
Osteoporotic fractures occur due to minimal trauma (a fall from standing height) or even spontaneously:
- Vertebral fractures: the most frequent (vertebral compressions). They can be asymptomatic or cause acute back pain, loss of height, and progressive kyphosis (the “hunchback” of the elderly)
- Proximal femur fracture: the most severe, with a mortality rate of 15-25% in the first year. Requires surgical intervention
- Wrist fracture (Colles): the classic fracture from falling on an outstretched hand
- Humerus fracture: frequent in falls
Consequences of Osteoporotic Kyphosis
Multiple vertebral fractures cause progressive thoracic kyphosis with:
- Loss of height (up to 10-15 cm)
- Chronic back pain (back pain)
- Reduced lung capacity
- Abdominal compression with digestive disorders
- Loss of balance and increased fall risk
- Psychological impact (depression, isolation)
Role of Physical Exercise
Why Exercise is Fundamental
Bone responds to mechanical stimulus (Wolff’s Law): when subjected to loads, osteoblasts activate and produce new bone. A sedentary lifestyle removes this stimulus and accelerates bone loss.
Physical exercise in osteoporosis acts on two fronts:
- Direct stimulus on the bone: weight-bearing exercises (weight, impact) stimulate bone formation
- Fall prevention: balance, strength, and coordination exercises reduce the risk of falling by 30-40%

Effective Types of Exercise
- Weight-bearing exercises: walking, light jogging, stairs, dancing — the impact of the foot on the ground stimulates the bone
- Resistance exercises (muscle strengthening): the pull of the muscle on the bone stimulates bone formation. Strengthening is also effective for areas not subjected to load (forearm, vertebrae)
- Balance and coordination exercises: reduce the risk of falling (tai chi, yoga, proprioceptive exercises)
- Postural exercises: to prevent or slow down kyphosis (spinal extension exercises)
What to Avoid
- Spinal flexion under load: bending the back forward with weights (risk of vertebral fracture)
- Uncontrolled high-impact movements: violent jumps, intense running in untrained individuals
- Sit-ups and crunches: repeated spinal flexion increases the risk of vertebral fracture in osteoporosis
Exercises for Osteoporosis
Osteoporosis is a progressive bone disease where resorption exceeds formation, causing decreased bone mineral density and increased fracture risk from minimal trauma. The program should be adapted to the severity of osteoporosis and the risk of fracture. Your physical therapist will personalize the program.
Muscle Strengthening (2-3 times a week)
Wall Squat
[IMAGE: Person standing with their back against a wall, feet 30 cm forward and shoulder-width apart. Knees slowly bend to about 45-60 degrees, then return to standing. The back remains in contact with the wall. Side view with detail of knee angle.]
Step-up on a step
[IMAGE: Person facing a step (15-20 cm) stepping up with one foot, then descending with controlled movement. Torso upright, knee aligned with foot. Side view.]
Back strengthening with resistance band (rowing)
[IMAGE: Person sitting with a straight back, a therapeutic resistance band fixed in front of them at chest height. Hands pull the band towards the chest, elbows bend at the sides of the body, shoulder blades come closer. The spine remains in extension (not flexion). Side view with detail of upright posture.]
Anti-Kyphosis Postural Exercises
Prone Thoracic Extension
[IMAGE: Person lying prone on a mat with hands at the sides of the head or under the forehead. The chest lifts slightly off the mat by extending the thoracic spine, keeping the gaze towards the floor. The elevation is moderate (not hyperextension). Side view with detail of chest lift.]
Standing Scapular Retraction (chin tuck + retraction)
[IMAGE: Person standing with their back against a wall, feet 10 cm from the wall. The chin retracts (chin tuck), shoulder blades move closer to the wall. Arms in a “candlestick” position (elbows at 90 degrees) press against the wall. The spine lengthens upwards. Side view showing postural alignment.]
Balance (fundamental for fall prevention)
Single-leg Stand
[IMAGE: Person standing on one leg next to a chair (for safety). The other leg is slightly lifted off the floor. Arms are open for balance. Hold for 30 seconds per side. Front view.]
Tandem Walk (heel-to-toe)
[IMAGE: Person walking along a straight line by placing the heel of one foot directly in front of the toes of the other foot (heel-to-toe walk), as if on a tightrope. Arms are open for balance. Side view showing the succession of heel-to-toe steps.]
Weight-Bearing Aerobic Activity
Brisk Walking
30 minutes of brisk walking, 5 times a week. The impact of the foot on the ground is the mechanical stimulus for the bone. Climbing stairs also counts.
Dancing
An excellent activity for osteoporosis: it combines weight-bearing, coordination, balance, and social interaction.

Pharmacological Treatment
Pharmacological therapy should be prescribed by your doctor based on fracture risk:
- Calcium + Vitamin D: the basis of treatment. Calcium 1000-1200 mg/day, Vitamin D 800-2000 IU/day
- Bisphosphonates (alendronate, risedronate): inhibit bone resorption. The most commonly prescribed class
- Denosumab: anti-RANKL monoclonal antibody, inhibits resorption
- Teriparatide: parathyroid hormone analog, stimulates bone formation — indicated for severe osteoporosis
- Romosozumab: anti-sclerostin antibody, stimulates formation and inhibits resorption
Prevention
In Young Age (Building the “bone bank account”)
- Regular physical activity: impact sports (running, jumping, basketball) during childhood and adolescence build peak bone mass that will protect throughout life
- Calcium-rich diet: milk, cheese, yogurt, leafy green vegetables, almonds
- Vitamin D: sun exposure, fatty fish, supplementation if necessary
- Avoid smoking and alcohol: especially during growth
In Adulthood and Old Age
- Regular exercise: muscle strengthening + weight-bearing activity + balance
- Calcium and vitamin D: check levels and supplement if necessary
- Periodic DEXA: after age 65 (women) or as medically indicated
- Fall prevention: remove hazards at home (rugs, poor lighting), check eyesight, review medications
- Do not smoke, limit alcohol

Differences Between Osteoporosis and Osteopenia
Osteoporosis and osteopenia are both conditions affecting bone density, but they differ in severity and progression. Osteopenia represents low bone mass that may progress to osteoporosis if left unaddressed, while osteoporosis involves significant bone loss with increased fracture risk. Both conditions are typically asymptomatic in early stages, making regular screening essential. The key distinction lies in bone mineral density measurements and the urgency of intervention.
| Osteoporosis | Osteopenia | |
|---|---|---|
| Main cause | Severe bone mineral loss due to age, hormones, or disease | Moderate bone mineral loss, early-stage condition |
| Diagnosis | DEXA scan T-score below -2.5 | DEXA scan T-score between -1.0 and -2.5 |
| Treatment | Medication, supplements, physical therapy required | Lifestyle changes, exercise, dietary improvements |
| Recovery time | Months to years with consistent intervention | Several months to 1-2 years with preventive measures |
Frequently Asked Questions (FAQ)
Osteoporosis cannot be “cured” but it can be slowed down, stabilized, and partially reversed with appropriate treatment (medication + exercise + nutrition). Modern medications can increase bone density by 5-10% in 2-3 years and reduce fracture risk by 40-70%.
Yes, walking is the most accessible exercise with good evidence for osteoporosis. The impact of the foot on the ground stimulates bone formation in the legs and pelvis. However, walking alone is not enough: it should be combined with muscle strengthening (which also stimulates the vertebrae and wrist) and balance exercises.
Swimming is an excellent cardiovascular exercise but it is not effective for osteoporosis because water cancels out the force of gravity and does not generate the mechanical impact necessary to stimulate bone. For osteoporosis, weight-bearing activities are preferable: walking, stairs, dancing, strength training with weights.
Yes, but the program must be carefully personalized to avoid spinal flexion under load. Your physical therapist will design a safe program that prioritizes spinal extension, strengthening of the back extensor muscles, and balance exercises.
No, it also affects men, although less frequently. One in five men over 50 will experience an osteoporotic fracture. Male osteoporosis is often unrecognized and underestimated. The main risk factors in men are: corticosteroids, hypogonadism, alcohol, smoking, and a sedentary lifestyle.
DEXA is recommended for all women at age 65 and for younger women with risk factors (early menopause, corticosteroid use, family history of fractures). For men, it is indicated at age 70 or earlier if risk factors are present. Your doctor will advise on the timing.

Frequently Asked Questions
Can osteoporosis be cured?
Osteoporosis is a treatable condition focused on managing bone mineral density and reducing fracture risk. While complete reversal of bone loss to pre-osteoporotic levels may not always be achievable, effective treatments can significantly improve bone health and prevent further deterioration.
Is walking good for osteoporosis?
Walking is a beneficial weight-bearing exercise for individuals with osteoporosis. It helps stimulate bone formation and maintain bone density, contributing to overall bone health.
Is swimming good for osteoporosis?
Swimming is an excellent exercise for cardiovascular health and muscle strengthening, but it is not a weight-bearing activity. Therefore, while it offers many health benefits, it does not directly contribute to increasing bone mineral density in the same way as weight-bearing exercises.
Can I exercise if I have already had a vertebral fracture?
Exercise is generally recommended even after a vertebral fracture, but it requires careful consideration and professional guidance. A physical therapist can design a safe and effective exercise program tailored to individual needs, focusing on appropriate movements and avoiding high-impact or spinal flexion activities.
