Bone just happens to be a harder type of tissue. Bone is always changing. Your body keeps your bones strong and healthy by replacing old bone with new bone. When someone has osteoporosis, the body removes more bone than it replaces. This means that bones get weaker and are more likely to break.
Osteoporosis is a bone disease that is quite common, especially in older women.
However, young people and men can develop osteoporosis, too. Osteoporosis can be prevented, and with proper therapy it can be effectively managed. In the early stages of osteoporosis, people often have no pain or other symptoms. While osteoporosis can affect any bone, the spine, wrist, and hip are the bones most likely to break. Many things put people at risk for osteoporosis.
