Osteoporosis decreases bone density by disrupting the balance between bone resorption and bone formation. As bone density diminishes, bones become more fragile and susceptible to fractures. This condition is often age-related and can be exacerbated by factors such as low calcium intake, hormonal changes, and lack of physical activity. Preventing osteoporosis involves ensuring adequate nutrient intake and engaging in weight-bearing exercises to enhance bone strength. Early intervention is crucial to maintain optimal bone health and reduce the risk of fractures.
