What is osteoporosis

Bone is living tissue and is constantly changing. From birth, our bones are developing and strengthening and reach their peak mass when we are in our 20s.1
Bones undergo wear and tear all the time. To prevent lasting damage old bone is dissolved by the body (resorption) and new bone grows back (formation). Osteoporosis literally means porous bone and occurs when old bone is dissolved more quickly than new bone is grown1.
