Rather than being a diagnosis of exclusion, irritable bowel syndrome (IBS) is a diagnosis that can be identified by symptom-based criteria. The collection of these criteria by a meticulous history can be enhanced by using various tools. Once a positive diagnosis is made, using clinical criteria for diagnosis, one should look for alarm or warning symptoms or signs, and should characterize the type of bowel habit. Determining whether the condition is a diarrhea-predominant or a constipation-predominant IBS will direct further diagnostic evaluation and management.
肠易激综合征（IBS）并非排除性诊断，而是一种可通过基于症状的标准来识别的诊断。通过使用各种工具，详细的病史采集可以更好地收集这些标准。一旦根据临床诊断标准做出阳性诊断，就应寻找警示或预警症状或体征，并对排便习惯类型进行特征描述。确定病情是腹泻型还是便秘型肠易激综合征将指导进一步的诊断评估和管理。
