Understanding Osteoporosis:

Causes, Symptoms, Diagnosis, Treatment and Prevention.

Osteoporosis is a progressive bone disease characterized by decreased bone mineral density and deterioration of bone microarchitecture. This leads to weakened bones that are more susceptible to fractures, even from minor falls or bumps. Although osteoporosis can occur in anyone, it is more common in older people, especially postmenopausal women. This guide explores the causes, symptoms, diagnosis, treatment options and preventative measures of osteoporosis.

What is Osteoporosis?

Healthy bones constantly undergo a remodeling process, during which old bone tissue is broken down and replaced with new bone. In osteoporosis, this delicate balance is disrupted. Bone resorption (degradation) exceeds bone formation, leading to a net loss of bone mass and an increased risk of fracture.

Causes of osteoporosis

Several factors contribute to the development of osteoporosis: 

  • Age: Bone mass naturally decreases with age. As we reach our thirties, bone breakdown begins to outpace bone formation. 
  • Hormonal Changes: Decreased estrogen production in women after menopause is a significant risk factor. Estrogen plays a crucial role in bone health. Men also experience a gradual decline in their testosterone levels as they age, which can contribute to bone loss. 
  • Family history: Having a close relative with osteoporosis increases your risk. 
  • Diet: Inadequate intake of calcium and vitamin D can hinder bone formation and contribute to osteoporosis. 
  • Certain medical conditions: Conditions such as rheumatoid arthritis, celiac disease, and hyperthyroidism can affect bone health. 
  • Medications: Long-term use of certain medications, such as corticosteroids, can contribute to bone loss. 
  • Lifestyle factors: Smoking, excessive alcohol consumption and a sedentary lifestyle can increase the risk of osteoporosis. 

Signs and symptoms of osteoporosis

Osteoporosis is often called a “silent disease” because it usually progresses without symptoms until a fracture occurs. However, some people might experience: 

  • Back pain caused by vertebral fractures of the spine. 
  • Loss of height over time due to vertebral compression fractures. 
  • A stooped (hunched) posture may develop as the spine weakens. 

It is important to note that these symptoms can sometimes be caused by other medical conditions. Consulting a healthcare professional for a proper diagnosis is crucial. Book your appointment today!

Diagnosis of osteoporosis

  • Medical History: A detailed discussion of your risk factors, family history, and any previous fractures. 
  • Physical exam: The healthcare professional will assess your posture, height, and check for any signs of spinal fracture. 
  • Dual Energy X-ray Absorptiometry (DXA Scan): This is the standard test for measuring bone mineral density and diagnosing osteoporosis. It uses low-dose X-rays to assess bone density in the hip and spine, the most common sites of fractures due to osteoporosis. 

Treatment Options for Osteoporosis

Osteoporosis treatment focuses on preventing future fractures and managing pain if they occur. Here is an overview of common treatment strategies: 

These are crucial for bone health and include: 

  • Diet: A balanced diet, rich in calcium and vitamin D is essential. Calcium is the building block of bones and 
  • Weight-bearing Exercise: Regular weight-bearing exercises like walking, jogging, or dancing help stimulate bone formation and improve strength and balance. 
  • Smoking Cessation: Smoking weakens bones and hinders healing. Quitting smoking is essential for bone health. 
  • Moderate Alcohol Consumption: Excessive alcohol consumption can contribute to bone loss.

Several medications can help prevent bone loss and reduce fracture risk:  

  • Bisphosphonates: These are the mainstay medications for osteoporosis and work by slowing down bone resorption. 
  • Denosumab: This medication inhibits a protein that promotes bone breakdown. 
  • Selective Estrogen Receptor Modulators (SERMs): These medications can help maintain bone density in postmenopausal women. 
  • Calcitonin: This medication may help reduce bone pain and may be used in combination with other osteoporosis medications. 
  • Parathyroid hormone therapy: This therapy can stimulate bone formation, but is usually only used in specific cases due to potential side effects. 

It is important to note that the choice of medications depends on individual factors and should be discussed with a healthcare professional.

Osteoporosis prevention

The good news is that osteoporosis can be prevented or its progression slowed by focusing on healthy lifestyle habits from a young age. Here are some key preventative measures: 

  • Calcium and vitamin D deficiency: Ensure adequate calcium and vitamin D intake throughout life. This can be achieved through a balanced diet, rich in foods containing calcium (dairy products, leafy green vegetables) and sources rich in vitamin D (oily fish, egg yolks). Supplementation may be necessary if dietary intake is insufficient. 
  • Weight-bearing exercises: Regular weight-bearing exercises that force your body to fight against gravity are essential for bone health. Aim for at least 30 minutes of moderate-intensity exercise most days of the week. 
  • Maintain a healthy weight: Being overweight or underweight can increase the risk of osteoporosis. 
  • Healthy lifestyle choices: Avoid smoking, excessive alcohol consumption, and leading a sedentary lifestyle. These habits can contribute to bone loss. 
  • Bone density screening: For adults at higher risk, considering bone density screening with a DXA scanner may be helpful for early detection and intervention. 

By following these preventative measures and consulting a doctor if you have concerns about bone health, you can significantly reduce your risk of developing osteoporosis and maintain strong, healthy bones throughout your life.
