Irritable Bowel Syndrome
Irritable bowel syndrome (IBS) is a chronic condition of the digestive system. This condition causes abdominal pain and altered bowel habits1. The main complaints are either frequent, watery bowel movements (diarrhoea) or not frequent enough bowel movements (constipation). In some patients these symptoms may switch between diarrhoea and constipation1. IBS is the most commonly diagnosed gastrointestinal condition2. In 1991, IBS was listed second as a cause of absence from work, only behind the common cold3. More recent data suggest that this gap is even decreasing: not only a high economic impact but also a substantial decrease in patients’ quality of life could be observed4. An estimated 10–20%1 of people in the general population experience symptoms of IBS, although only about 15% of affected people actually seek medical help5. Although the condition cannot be cured, treatments are available to alleviate symptoms.
