What is a key feature of osteoporosis?

A key feature of osteoporosis is decreased bone density. This condition is characterized by a loss of bone mass and deterioration of bone tissue, leading to an increased risk of fractures. Osteoporosis typically occurs when the balance between bone resorption (breakdown) and bone formation shifts in favor of resorption, causing bones to become weaker and more porous.

As bone density decreases, the structural integrity of bones is compromised, making them more fragile. This is particularly crucial for older adults, as they are at a higher risk for osteoporosis due to age-related changes in bone metabolism and hormonal shifts, particularly in postmenopausal women with decreased estrogen levels.

In contrast, increased bone density, joint inflammation, and increased muscle mass are not characteristic of osteoporosis. Increased bone density suggests stronger bones, joint inflammation is more associated with conditions like arthritis, and increased muscle mass relates to overall fitness and strength rather than bone health.
