What happens during Osteoporosis

  • Osteoporosis is a disease in which the bones become weak and can break easily. Often people don't know that they have osteoporosis until a bone actually breaks (or fractures).
  • Any bone can be affected by osteoporosis, but the most common bones that break are in the hip, back and wrist.
  • The condition is quite serious because fractures can lead to pain, hospitalizations, surgery, disability and even death.
  • Bones are made up mostly of proteins and minerals. Two minerals that are especially important in bone are calcium and phosphorus. Bones are living tissues and old bone cells are always being replaced by new ones.
  • There are special cells that build upnew bone (Osteoblasts) while other cells (Osteoclasts) break down the old bone.
As people get older, their bodies don't replace all the bone that has been broken down, and bones tend to become weaker and more likely to break.
