Symptoms and causes

What is it?

Osteoporosis literally means'porous bone'. Both the quantity and quality of the bones decrease. Bone breakdown occurs too quickly, and the formation of replacement bone lags behind. This reduces bone strength , increasing the risk of fractures (bone breaks).

Causes and risk factors

  • Increasing age
  • Female gender
  • Smoking
  • Excessive alcohol consumption (more than 2-3 units per day)
  • Genetic predisposition (e.g., a parent with osteoporosis or a history of hip fractures)
  • Previous bone fracture after the age 50
  • Prolonged bed rest or immobility, insufficient exercise
  • Thyroid disorders (hypothyroidism)
  • Diabetes
  • Rheumatoid arthritis
  • Body weight or BMI too low
  • Long-term use of certain medications (e.g. corticosteroids)
  • Early menopause
  • Low levels of vitamin D in the bloodstream

Consequences

As mentioned above, the main consequence of osteoporosis is the significantly higher risk of fractures. Additionally, the risk of falling increases with age. In individuals, 1 in 3 women and 1 in 5 men over the age of 50 will suffer a fracture due to osteoporosis. Hip and wrist fractures are the most common fractures caused by falls. Vertebral collapses and fractures also occur regularly. These may even occur spontaneously.

Diagnosis and treatment

Diagnosis and treatment

Diagnosis

To diagnose osteoporosis, the physician will listen to your story and specifically ask about your history of falls and/or bone fractures. Additionally, a blood test will be performed, and X-rays may be taken if fractures are suspected. A bone density test (DEXA) also provides the physician with crucial information to diagnose osteoporosis and assess the risk of fractures.

Treatment

The treatment of osteoporosis involves a number of measures, the most important of which is to maintain or adopt a healthy lifestyle. Medication-based measures can also be taken.

A few tips:

  • Keep moving: exercise strengthens muscles, balance, reactivity and bone formation. This reduces your risk of falls and fractures.
  • Sunlight exposure: try to spend 15-30 minutes daily outdoors with your face and hands uncovered.
  • Healthy eating:
    • Calcium-rich diet (3 to 4 dairy products per day)
    • Vitamin D (oily fish, egg yolks, spread and prepared fats)
  • Limit alcohol consumption: no more than 3 alcoholic drinks per day.
  • Quit smoking
  • Fall prevention (read more about falls here)
  • Vitamin D supplement (if calcium and vitamin D intake is too low)
  • Medication for osteoporosis treatment

Your physician can determine the most appropriate medication for you. Ask for it!
