**What is osteoporosis and how is it prevented?**
Osteoporosis is a condition characterized by weakened bones, increasing the risk of fractures. Prevention strategies revolve around maintaining healthy bone density through adequate intake of calcium and vitamin D, which are essential for bone strength. Regular weight-bearing exercise also promotes bone health by stimulating bone formation. Avoiding smoking and excessive alcohol consumption further aids in prevention. Early assessment and lifestyle choices play significant roles in managing bone health throughout life, especially in older adults.
