What is the bone disorder characterized by decreased density of bone?

Osteoarthritis
Rheumatoid arthritis
Osteoporosis
Paget's disease

The correct answer is: Osteoporosis

The bone disorder characterized by decreased density of bone is osteoporosis. This condition is primarily marked by a reduction in bone mass and structural deterioration of bone tissue, which leads to an increased risk of fractures. Osteoporosis often develops silently over many years, with individuals typically unaware of their decreasing bone density until they experience a fracture from a low-impact event. Factors contributing to osteoporosis include hormonal changes, particularly decreased estrogen levels after menopause in women, inadequate intake of calcium and vitamin D, a sedentary lifestyle, and certain health conditions or medications that can affect bone metabolism. Effective preventive measures and treatments focus on improving bone density through lifestyle modifications, dietary adjustments, and medication when necessary. Understanding osteoporosis is crucial for appropriate diagnosis and management in clinical settings.
