Fibromyalgia, also called fibromyalgia syndrome (FMS), is a long-term condition that causes pain all over the body.
As well as widespread pain, people with fibromyalgia may also have:
- increased sensitivity to pain
- fatigue (extreme tiredness)
- muscle stiffness
- difficulty sleeping
- problems with mental processes (known as “fibro-fog”) – such as problems with memory and concentration
- irritable bowel syndrome (IBS) – a digestive condition that causes stomach pain and bloating
What causes fibromyalgia?
The exact cause of fibromyalgia is unknown, but it’s thought to be related to abnormal levels of certain chemicals in the brain and changes in the way the central nervous system (brain, spinal cord and nerves) processes pain messages carried around the body.
It’s also suggested that some people are more likely to develop fibromyalgia because of genes inherited from their parents.
In many cases, the condition appears to be triggered by a physically or emotionally stressful event, such as:
- an injury or infection
- giving birth
- having an operation
- the breakdown of a relationship
- the death of a loved one
Who is affected?
Anyone can develop fibromyalgia, although it affects around seven times as many women as men. The condition typically develops between the ages of 30 and 50, but can occur in people of any age, including children and the elderly.
It’s not clear exactly how many people are affected by fibromyalgia, although research has suggested that it could be a relatively common condition. Some estimates suggest nearly 1 in 20 people may be affected by fibromyalgia to some degree.
One of the main reasons it’s not clear how many people are affected is because fibromyalgia can be a difficult condition to diagnose. There is no specific test for the condition, and the symptoms can be similar to a number of other conditions.
