What is osteoporosis?

• A. A progressive skeletal disease resulting in diminished bone density and increased fracture risk
• B. A temporary muscle weakness condition
• C. A skin disorder
• D. A metabolic bone growth disorder

Answer: (A)

Osteoporosis is a progressive skeletal disease in which bone mass and density decline, and the internal bone structure becomes more porous and brittle. This weakening makes bones much more prone to fractures from everyday stresses, like a simple fall or even a minor twist. The problem arises because bone remodeling shifts toward resorption faster than formation, a process that accelerates with age and is promoted by factors such as lower estrogen after menopause, inadequate calcium and vitamin D, and physical inactivity. It’s typically asymptomatic until a fracture occurs, which is why screening with bone density testing (DXA) is important for at-risk individuals. Treatment focuses on strengthening bones and reducing fracture risk through calcium and vitamin D, weight-bearing exercise, fall prevention, and medications that slow bone loss or stimulate bone formation. This description aligns with a chronic loss of bone density and increased fracture risk, rather than a temporary muscle weakness or a skin disorder, or a condition that involves abnormal bone growth during development.
