More effective remedies for Irritable Bowel Syndrome (IBS) are needed, as well as increased availability of treatments shown to be effective against IBS, such as hypnosis, says a comment in this weeks special gastroenterology edition of The Lancet.

He says: "IBS is one of the commonest reasons for a consultation. However, because the disorder is poorly understood, many doctors find patients with IBS difficult to treat.
"Although extra time and effort may be needed, successful management is rewarding because it can substantially improve quality of life."
IBS has a similar incidence in Europe and the USA, and is increasingly recognised in developing countries, with between 5-10% of the population estimated to be affected.
Patients who present with IBS are typically female, aged 20-40 years. Most patients have abdominal pain or discomfort intermittently, with flares of pain lasting two to four days. Other symptoms include bloating, abnormal stool frequency and abnormal defecation.
IBS is also associated with psychological distress, with 50% of IBS patients who seek medical care also suffering stress or anxiety. IBS patients also have substantially increased health-care costs, with patients consulting their primary-care physician twice as often as non-IBS patients. A third of IBS patients are referred to secondary care and also onto sometimes unnecessary specialties.
Professor Spiller says: "Most IBS patients require reassurance, explanation and lifestyle advice."
