The Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder
characterised by abdominal pain and distension and bowel dysfunction. It is a
distressing condition causing pain, loose bowels, constipation or a fluctuation
between the two. IBS is one of the most common intestinal disorders and it is a long-term condition.
The cause of IBS is not well understood. IBS can develop at any age, but most
people have their first symptoms between the ages of 15 and 40. Women are more
likely to get IBS and to have more severe symptoms. IBS is now one of the most
common problems of the digestive system; about one in six people in the UK have
symptoms. Most people with IBS find their symptoms an occasional nuisance, but
don't need to see a doctor. However, for others the condition seriously affects
their quality of life. Treatment for IBS will include dietary modification as
it is clear that food intolerance plays a role.
