What is osteoporosis?

Osteoporosis is defined as a bone disorder characterized by decreased bone density, making the bones more porous and fragile. This condition leads to a higher risk of fractures, particularly in the hip, spine, and wrist. The decreased density results from a variety of factors, including hormonal changes, nutritional deficiencies (especially calcium and vitamin D), and a sedentary lifestyle. Osteoporosis is often considered a “silent disease” because bone loss occurs without symptoms unless a fracture occurs.

This understanding highlights the importance of early detection and preventative measures, such as weight-bearing exercises and dietary modifications, to maintain healthy bone density. Thus, option C correctly describes osteoporosis as a disorder where the bone density is decreased, leading to the consequences associated with the condition.
