Irritable bowel syndrome (IBS) usually is considered a functional gastrointestinal disorder characterized by pain, bloating and either diarrhea or constipation, but a small subgroup of patients report a sudden onset of their IBS symptoms after gastroenteritis, that is named postinfectious IBS. IBS can be diagnosed with confidence when a patient fulfills the Rome II criteria for IBS and displays no warning signs, as determined by a careful history and physical examination. In the past numerous test were considered routine for patients with suspected IBS, however, available data do not support this approach. The etiology of IBS remains unknown and therefore the treatment is focused on relieving symptoms rather than curing the disease. The patient main complaints such as constipation, diarrhea or bloating-pain-gas, determine the therapies of choice, according the severity of them.
肠易激综合征（IBS）通常被认为是一种功能性胃肠疾病，其特征为疼痛、腹胀以及腹泻或便秘，但是一小部分患者报告称他们的肠易激综合征症状在肠胃炎后突然发作，这被称为感染后肠易激综合征。当患者符合肠易激综合征的罗马II标准且未表现出由仔细的病史和体格检查所确定的警示体征时，肠易激综合征可以被确诊。过去，对于疑似肠易激综合征的患者，许多检查被视为常规检查，然而，现有数据并不支持这种做法。肠易激综合征的病因仍然不明，因此治疗重点在于缓解症状而非治愈疾病。根据便秘、腹泻或腹胀-疼痛-气体等主要症状的严重程度，确定患者的首选治疗方法。
