Because functional bowel disorders have no reliable markers, they must be defined by their symptoms. The various constellations of symptoms (syndromes) may have different mechanisms, differential diagnoses, and treatments. Therefore, precise classification is important on clinical and scientific grounds. Functional bowel disorders are a subset of functional gastrointestinal disorders attributed to the intestine. By symptoms they may be subclassified as IBS, burbulence, functional constipation and functional diarrhea. "Orphan" symptoms insufficient to qualify as one of these syndromes may be classified as unspecified functional bowel disorder. There may be overlap in symptoms among the disorders. A more careful definition of these symptom complexes will permit a logical approach to their study, investigation, and management.
由于功能性肠病没有可靠的标志物，因此必须根据其症状来定义。各种症状组合（综合征）可能有不同的机制、鉴别诊断和治疗方法。因此，精确分类在临床和科学方面都很重要。功能性肠病是功能性胃肠病中归因于肠道的一个子集。根据症状，它们可再细分为肠易激综合征、肠胃气胀、功能性便秘和功能性腹泻。不足以归为这些综合征之一的“孤立”症状可归类为未特定的功能性肠病。这些疾病之间可能存在症状重叠。对这些症状复合体进行更仔细的定义将有助于对其进行合理的研究、调查和管理。
