IBS sufferers often show symptoms affecting the small or large bowel, which can cause pain and discomfort. The exact causes of IBS are unknown as IBS sufferers usually have no physical abnormalities in the bowel, so it is widley accepted that there is a strong link between stress and IBS.
IBS sufferers may experience a combination of some of these symptoms, with one symptom in particular occurring more regularly or with greater severity. Symptoms vary from the mild, where they don't really affect someone's quality of life, to the serious, prompting the sufferer to seek medical help.
Because Irritable Bowel Syndrome is such a loose collection of symptoms, there is no one definitive 'cure' for IBS. However, there are a number of self-help treatments that can alleviate and improve symptoms, such as diet and therapies such as hypnosis.
