What characterizes osteoporosis?

• A. Excessive bone growth
• B. Compromised bone strength
• C. Healthy bone density
• D. Increased bone formation

Answer: (B)

Osteoporosis is primarily characterized by compromised bone strength, which results from a reduction in bone mass and deterioration of bone tissue. This condition leads to an increased risk of fractures and breaks, often occurring with minimal or no trauma. The structural integrity of bones is weakened, making them more susceptible to damage.

In osteoporosis, the balance between bone resorption (the process of bone being broken down) and bone formation is disrupted, often due to factors such as hormonal changes, nutritional deficiencies (like low calcium or vitamin D), and lifestyle choices (like inactivity). This imbalance results in a net loss of bone density and quality over time, hence defining the condition.

The other options do not accurately represent the characteristics of osteoporosis. Excessive bone growth, healthy bone density, and increased bone formation do not align with the pathophysiology of osteoporosis, which is fundamentally about diminished bone strength and increased fragility. Understanding these distinctions is crucial for properly identifying osteoporosis and implementing effective management strategies.
