Osteoporosis - Overview

Overview-Osteoporosis




Osteoporosis is a health condition that weakens bones, making them fragile and more likely to break. It develops slowly over several years and is often only diagnosed when a fall or sudden impact causes a bone to break (fracture).
The most common injuries in people with osteoporosis are:
However, breaks can also happen in other bones, such as in the arm or pelvis. Sometimes a cough or sneeze can cause a broken rib or the partial collapse of one of the bones of the spine.
Osteoporosis is not usually painful until a bone is broken, but broken bones in the spine are a common cause of long-term pain.
Although a broken bone is often the first sign of osteoporosis, some older people develop the characteristic stooped (bent forward) posture. It happens when the bones in the spine have broken, making it difficult to support the weight of the body.
Osteoporosis can be treated with bone strengthening medicines.

Bone loss before osteoporosis (osteopenia)

The stage before osteoporosis is called osteopenia. This is when a bone density scan shows you have lower bone density than the average for your age, but not low enough to be classed as osteoporosis.
Osteopenia does not always lead to osteoporosis. It depends on many factors.
If you have osteopenia, there are steps you can take to keep your bones healthy and reduce your risk of developing osteoporosis.
Your doctor may also prescribe one of the bone-strengthening treatments that are given to people with osteoporosis, depending on how weak your bones are and your risk of breaking a bone.

Who's affected by osteoporosis?

Osteoporosis affects over 3 million people in the UK.
More than 500,000 people receive hospital treatment for fragility fractures (bones that break after falling from standing height or less) every year as a result of osteoporosis.

Causes of osteoporosis

Losing bone is a normal part of ageing, but some people lose bone much faster than normal. This can lead to osteoporosis and an increased risk of broken bones.
Women also lose bone rapidly in the first few years after the menopause. Women are more at risk of osteoporosis than men, particularly if the menopause begins early (before the age of 45) or they've had their ovaries removed.
However osteoporosis can also affect men, younger women and children.
Many other factors can also increase the risk of developing osteoporosis, including:
  • taking high-dose steroid tablets for more than 3 months.
  • other medical conditions – such as inflammatory conditions, hormone-related conditions, or malabsorption problems
  • a family history of osteoporosis – particularly a hip fracture in a parent
  • long-term use of certain medicines that can affect bone strength or hormone levels, such as anti-oestrogen tablets that many women take after breast cancer
  • having or having had an eating disorder such as anorexia or bulimia
  • having a low body mass index (BMI)
  • not exercising regularly
  • heavy drinking and smoking

Diagnosing osteoporosis and osteopenia

If your doctor suspects you have osteoporosis, they can work out your future risk of breaking a bone using an online programme, such as FRAX or Q-Fracture.

Bone density scan (DEXA scan)

They may also refer you for a bone density scan to measure your bone strength. It's a short, painless procedure that takes 10 to 20 minutes, depending on the part of the body being scanned.
Your bone density can be compared to that of a healthy young adult. 
The difference is calculated as a standard deviation (SD) and is called a T score.
Standard deviation is a measure of variability based on an average or expected value. A T score of:
  • above -1 SD is normal 
  • between -1 and -2.5 SD shows bone loss and is defined as osteopenia
  • below -2.5 shows bone loss and is defined as osteoporosis

Treating osteoporosis

Treatment for osteoporosis is based on treating and preventing broken bones, and taking medicine to strengthen your bones.
The decision about whether you need treatment depends on your risk of breaking a bone in the future. This will be based on a number of factors such as your age, sex and the results of your bone density scan.
If you need treatment, your doctor can suggest the safest and most effective treatment plan for you.

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 Royal Osteoporosis Society can put you in touch with local support groups.

Osteoporosis support

The Royal Osteoporosis Society is the UK's national charity for osteoporosis.
It has detailed information on osteoporosis prevention and treatment.
It can put you in touch with local support groups. It also has a free telephone helpline that may be particularly helpful if you're newly diagnosed with osteoporosis.
