Irritable bowel syndrome (IBS) is a common functional gastrointestinal (GI) disorder. Because not everyone needs to seek care, population-based studies are needed to truly understand the epidemiology of IBS. About 10% of the population has IBS at any one time and about 200 people per 100,000 will receive an initial diagnosis of IBS over the course of a year. IBS patients are more frequently younger in age, and a female predominance has been observed in Western countries and tertiary care settings. IBS patients commonly report overlapping upper GI, as well as a variety of non-GI, complaints.
肠易激综合征（IBS）是一种常见的功能性胃肠道（GI）疾病。由于并非每个人都需要寻求医疗，因此需要进行基于人群的研究才能真正了解 IBS 的流行病学。任何时候约有 10%的人口患有 IBS，并且每 10 万人中约有 200 人在一年内首次被诊断出患有 IBS。IBS 患者通常年龄较小，在西方国家和三级保健机构中观察到女性居多。IBS 患者通常报告有重叠的上胃肠道，以及各种非胃肠道症状。
