Play an AI-generated podcast conversation about this lesson

Why is osteoporosis often referred to as a 'silent' disease?

Many people are unaware they have the disease until a fracture occurs. (correct)
It primarily affects individuals who are unable to communicate their symptoms effectively.
The symptoms are psychological rather than physical, making them difficult to detect.
The disease progresses so rapidly that symptoms are easily missed during routine checkups.

Which fracture locations are most commonly associated with osteoporosis?

Hips, spinal vertebrae, and wrists (correct)
Knees, elbows, and shoulders
Fingers, toes, and skull
Ribs, clavicle, and ankles

Which of the following is NOT typically a symptom of vertebral fracture due to osteoporosis?

Spine malformations or kyphosis
Increased height (correct)
Severe back pain
Loss of height
