Final answer:
Osteoporosis is a condition where bones lose mass and become brittle. It is caused by an imbalance in bone formation and resorption. Option 1 is correct.
Step-by-step explanation:
Osteoporosis is characterized by bone mass loss, weakening, and heightened fragility, making it a prevalent cause of fractures in the elderly. The condition arises from an imbalance between bone formation and resorption during the bone remodeling process.
Factors contributing to osteoporosis include age-related decline in bone density, hormonal changes, underlying diseases, and specific medications. This disruption in bone homeostasis compromises skeletal integrity, rendering bones more susceptible to fractures.
As a widespread health concern, understanding the multifactorial causes of osteoporosis is crucial for developing effective preventive measures and therapeutic interventions to mitigate the risks associated with bone deterioration, especially in aging populations.
Therefore, option `1 is correct.
