What is osteoporosis primarily characterized by?

Osteoporosis is primarily characterized by a reduction in bone mineral content. This condition leads to bones becoming less dense, which significantly increases the risk of fractures and breaks. The reduction in bone mineral density means that bones are weaker and more prone to damage, resulting from factors like aging, hormonal changes, and dietary deficiencies, particularly in calcium and vitamin D.

In contrast, a decrease in body fat, an increase in muscle mass, and a change in skin elasticity do not directly relate to the characteristics of osteoporosis. While they may involve different aspects of health and body composition, they are not relevant to the fundamental definition of osteoporosis. Understanding osteoporosis in the context of its impact on bone health is crucial for recognizing and addressing this condition effectively.
