Osteoporosis is a progressive condition that weakens the bones, making them more fragile and prone to fractures. It occurs when bones lose important minerals, such as calcium, faster than they can be replaced. This results in a decrease in bone density and causes the bones to become porous, leading to an increased risk of breaks, even from minor falls or injuries.
Often referred to as a “silent disease,” osteoporosis can develop gradually with few noticeable symptoms until a fracture happens. This highlights the importance of early detection and proactive management to maintain strong bones and prevent serious injury.
What is Osteoporosis?
Osteopenia refers to a condition where bone density is lower than normal but not yet low enough to be classified as osteoporosis. It is considered a precursor to osteoporosis, signaling that bone health is already compromised, and further loss could occur if not addressed. Individuals with osteopenia are at an increased risk of developing osteoporosis over time, but with the right lifestyle adjustments and medical interventions, the progression of the disease can often be slowed or even prevented.
What is Osteopenia?
Osteoporosis arises when the natural process of bone remodeling — where old bone tissue is replaced by new — becomes imbalanced. Over time, bones lose density because the body breaks down old bone faster than it can rebuild new bone tissue.
While bone loss can happen to anyone as they age, the process accelerates in women, especially after menopause, due to the decline in estrogen levels, a hormone vital for maintaining bone strength. In addition to aging, other factors can contribute to osteoporosis, including:
Lack of Physical Activity: Inactive lifestyles can lead to weaker bones.
Chronic Conditions: Diseases like rheumatoid arthritis, coeliac disease, and hyperthyroidism can affect bone health.
Hormonal Imbalances: Reduced estrogen in women and testosterone in men can increase the risk of bone loss.
Unhealthy Habits: Smoking, heavy alcohol consumption, and poor diet (particularly low calcium and vitamin D intake) are major contributors to bone density loss.

The Role of Physiotherapy in Managing Osteoporosis and Osteopenia
Physiotherapy is a key component in the management of osteoporosis and osteopenia, as it helps to strengthen bones, improve posture, and reduce the risk of falls. A physiotherapist will develop a tailored exercise plan to suit your specific condition and fitness level, gradually progressing from gentle movements to more intense strengthening exercises.
Individualised Plans for Osteoporosis and Osteopenia
It’s essential to note that treatment plans will vary between individuals with osteoporosis and osteopenia. People at a higher risk of fracture must follow specific precautions, such as modifying or avoiding certain positions and exercises.
For example, excessive trunk flexion exercises (e.g., forward bends) or forceful end-of-range twisting motions of the trunk should be avoided, as they can increase fracture risk. (Giangregorio & Ponzano, 2022). Always consult your doctor or physiotherapist to create a tailored plan that considers your condition, risk factors, and overall health.
Here’s how physiotherapy works through different stages:
Building a Foundation
In the early stages, the focus is on gentle, low-impact exercises that promote balance and stability, which are crucial for preventing falls. This stage includes:
Walking: A simple yet effective weight-bearing exercise that helps improve bone strength.
Balance Training: Exercises like standing on one foot or heel-to-toe walking to enhance coordination and prevent falls.
Gentle Stretching: Flexibility exercises to keep muscles limber and avoid stiffness.
Strengthening and Endurance
Once you’ve built a strong foundation, the next phase involves strengthening exercises to stimulate bone growth and improve overall muscle strength. This stage may include:
Resistance Band Exercises: Using bands for exercises like bicep curls, leg lifts, and chest presses.
Bodyweight Exercises: Squats, lunges, and modified push-ups to strengthen muscles and support bones.
Low-Impact Cardio: Activities such as cycling, swimming, or using an elliptical machine to improve cardiovascular health without excessive impact.
Advanced Strength Training
As your body adapts, you can progress to higher-intensity exercises that apply more mechanical load to the bones. These activities help stimulate bone density and build muscle mass, improving overall function. Examples include:
Weightlifting: Using dumbbells or kettlebells to perform exercises like deadlifts, overhead presses, and bench presses.
Jumping Exercises: Plyometrics, such as box jumps or skipping, which apply higher impact forces that can strengthen bones.
High-Impact Sports: Sports like tennis, basketball, or volleyball that involve quick movements and jumping to increase bone strength.
Certain factors increase the likelihood of developing osteoporosis, including:
Age: Bone density naturally decreases as we get older.
Gender: Women, especially post-menopausal women, are at higher risk due to hormonal changes.
Inactivity: Lack of weight-bearing exercise weakens bones.
Menopause: The drop in estrogen during menopause accelerates bone loss.
Chronic Health Conditions: Conditions like rheumatoid arthritis or coeliac disease can impact bone health.
Hormonal Imbalances: Conditions like hyperthyroidism can contribute to bone loss.
Lifestyle Factors: Smoking, excessive alcohol, and poor diet all contribute to weakened bones.
Nutritional Deficiencies: Insufficient intake of calcium and vitamin D can compromise bone strength.
Risk Factors for Osteoporosis
Diagnosing and Preventing Osteoporosis
When to Seek Help
Osteoporosis often goes unnoticed until a fracture occurs. Early diagnosis is key to managing the condition and preventing further bone loss. If you're at risk, or if you experience unexplained bone pain or fractures, it’s essential to consult your healthcare provider for a proper evaluation.
A bone density test (DEXA scan) is the gold standard for diagnosing osteoporosis, measuring your bone density against age-matched norms. This scan helps determine whether your bone health is at risk and how to address it.
Preventing Osteoporosis
Osteoporosis prevention begins early and focuses on building and maintaining strong bones throughout life. Key steps include:
Regular Exercise: Weight-bearing exercises, like walking, running, and strength training, help keep bones strong.
Healthy Diet: A diet rich in calcium and vitamin D supports bone health. Foods like dairy, leafy greens, and fortified foods are excellent choices.
Healthy Habits: Avoid smoking, limit alcohol consumption, and maintain a healthy weight.
Medical Management: If you have osteopenia or are at higher risk, your doctor may recommend medications or lifestyle changes to slow bone loss and prevent osteoporosis.
Whether you're managing osteopenia or osteoporosis, taking proactive steps to strengthen your bones is crucial. Starting with foundational exercises, progressing to strength training, and maintaining a healthy lifestyle can help protect your bones and prevent fractures. If you’re concerned about your bone health, consult with your physiotherapist or doctor to create a personalised plan that suits your needs and keeps you on the path to stronger bones.
