Osteoporosis is a medical condition that describes weak bones. The bones in your body are made up of living tissue that is constantly being removed and replaced. For bones to remain healthy and strong you need normal hormone levels, calcium, Vitamin D, proteins and weight bearing/strengthening exercise to keep them healthy.
Often osteoporosis arises because people lose more bone than normal and this causes bone to become fragile and to fracture more easily. The most common bones to fracture in people with osteoporosis are the hip, spine and wrist, but any bone can be affected.
Bone mineral density (BMD)
Low bone mineral density (BMD) means that the bone tissue in the skeleton is less dense and therefore potentially weaker. BMD is one of the measures used to determine if you have osteoporosis. Testing for low BMD can be done by having a simple and painless DXA scan of certain bones in your body, normally the spine and hips. The result of this test – your ‘T-score’ can help your doctor decide whether or not you have osteoporosis and also estimate your risk of having a fracture. These estimates enable the doctor to best determine what treatment plan is right for you.
