Osteoporosis is a condition that weakens bones, making them fragile and more likely to break.
It's a fairly common condition that affects around three million people in the UK. More than 300,000 people receive hospital treatment for fragility fractures (fractures that occur from standing height or less) every year as a result of osteoporosis.
Wrist fractures, hip fractures and fractures of the vertebrae (bones in the spine) are the most common type of breaks that affect people with osteoporosis. However, they can also occur in other bones, such as in the arm, ribs or pelvis.
There are usually no warnings you've developed osteoporosis and it's often only diagnosed when a bone is fractured after even minor falls.

What causes osteoporosis?
During childhood, bones grow and repair very quickly, but this process slows as you get older.
Bones stop growing in length between the ages of 16 and 18, but continue to increase in density until you're in your late 20s.
You gradually start to lose bone density from about 35 years of age. Women lose bone rapidly in the first few years after the menopause (when monthly periods stop and the ovaries stop producing an egg).
Losing bone is a normal part of the ageing process, but for some people it can lead to osteoporosis and an increased risk of fractures.
Other factors that increase your risk of developing osteoporosis include:

If your doctor suspects you have osteoporosis, they can make an assessment using an online programme, such as FRAX or Q-Fracture. They may also refer you for a scan to measure your bone mineral density.
This type of scan is known as a DEXA (DXA) scan. It's a short, painless procedure and your bone mineral density can then be used to assess your fracture risk.

Treatment for osteoporosis is based on treating and preventing fractures and using medication to strengthen bones.
The decision about what treatment you have – if any – will depend on your risk of fracture. This will be based on a number of factors, such as your age and the results of your DXA scan.

Living with osteoporosis
If you're diagnosed with osteoporosis, there are steps you can take to reduce your chances of a fall, such as removing hazards from your home and having regular sight tests and hearing tests.
To help you recover from a fracture, you can try using:
Speak to your GP or nurse if you're worried about living with a long-term condition. They may be able to answer any questions you have.
You may also find it helpful to talk to a trained counsellor or psychologist or other people with the condition.
The National Osteoporosis Society can put you in touch with local support groups, and they also have an online discussion forum.
