What Is Osteoporosis?
Osteoporosis is a debilitating disease characterized by low bone mass and, thus, bones that are susceptible to fracture. If not prevented or if left untreated, osteoporosis can progress painlessly until a bone breaks, typically in the hip, spine, or wrist. A hip fracture can limit mobility and lead to a loss of independence, while vertebral fractures can result in a loss of height, stooped posture, and chronic pain.
The bone disease osteoporosis is caused by more bone cells being reabsorbed than being deposited. This imbalance results in a progressive loss of bone density and a thinning of bone tissue. Osteoporotic bones are more porous and therefore more vulnerable to fracture. (Information and image from MedlinePlus®)
