Epidemiological characteristics and socioeconomic importance of irritable bowel syndrome.

In summary, in light of the flood of figures, statistics, and epidemiological evidence, the socioeconomic importance of IBS cannot be questioned. The development of new, effective treatments that would control the symptoms is a huge challenge for researchers and the pharmaceutical industry. Drugs able to relieve the symptoms of IBS would provide great relief to a large number of patients, and would save the health system considerable effort and resources.
