7. What is Osteoporosis?
Osteoporosis is a decrease in bone strength, which places a
person at high risk of a bone break or fracture. It is often
referred to as the 'silent disease' as it quite often goes
undiagnosed until a fracture or a break occurs. Osteoporosis is
preventable in the majority of cases. For further information on
