Irritable bowel syndrome (IBS) is 'out of the closet' and into the public domain. IBS is on news-stands throughout the world, regularly covered in health columns in daily newspapers, and weekly magazines, and also on radio and television. Why has IBS achieved such status? IBS is common, affecting 10-25% of the population, depending on geographical location, and definition. It affects men and women alike, although women more commonly seek medical advice. It is transcultural and can affect all age groups, although typically presenting in the third and fourth decades. Finally, although the condition is not associated with increased mortality, some individuals experience high morbidity with a profound impact on their ability to work or enjoy life.
