What is Osteoporosis?

Osteoporosis is a silent disease of the bones that makes them weaken and prone to fracture. Bone is living tissue that is in a constant state of regeneration, as old bone is removed (bone resorption) and replaced by new bone (bone formation).

By their mid-30s, most people begin to gradually lose bone strength as the balance between bone resorption and bone formation shifts, so that more bone is lost than can be replaced. As a result, bones become thinner and structurally weaker.

The disease is “silent” because there are no symptoms when you have osteoporosis, and the condition may come to attention only after you break a bone. When you have osteoporosis, this can occur even after a minor injury, such as a fall.

The most common fractures occur at the spine, wrist and hip. Spine and hip fractures in particular may lead to chronic pain, long-term disability and even death. The goal of treating osteoporosis is to prevent such fractures in the first place.
