What are the effects of osteoporosis?

• A. Bones become brittle and break more easily.
• B. Old bone cells prevent new bone cells from developing.
• C. Bones are not supplied with enough energy.
• D. Bones become stronger.

Answer: (A)

Osteoporosis weakens bones by reducing bone density, so they become brittle and break more easily. When bone density declines, the bone’s internal structure becomes porous, making even minor stresses or falls capable of causing fractures. That’s why this option, describing bones as brittle and fracture-prone, is the correct one.

The other statements don’t describe what happens in osteoporosis. It isn’t about old bone cells blocking new bone development, nor is it about bones lacking energy. And it certainly isn’t about bones becoming stronger; the condition makes bones weaker and more susceptible to breaks.
