Functional gastrointestinal disorders are most commonly divided into gastro-oesophageal reflux disease (GORD), dyspepsia and the irritable bowel syndrome (IBS). GORD is defined as having predominant reflux symptoms, and is nowadays not considered to be a subgroup of dyspepsia. Dyspepsia is divided into subgroups (ulcer-like, dysmotility-like, unspecified and sometimes, when reflux symptoms are combined with abdominal complaints, reflux-like dyspepsia). The clinical relevance of this is however doubtful. If dyspeptic symptoms occur with concomitant bowel habit disturbances, the subject is said to have IBS. In the clinical situation, the patients often present with symptom overlap, and with change in main symptom profile from time to time. Different definition makes prevalence reports less comparable. An approximate average in the literature of the three-month period prevalence of GORD is that it is reported by 10% of the population, of overall reflux symptoms by 25%, of dyspepsia (without predominant reflux symptoms) by 25%, of dyspepsia without concomitant reflux symptoms by 15% and of IBS by 15% of the population.
功能性胃肠病最常分为胃食管反流病（GORD）、消化不良和肠易激综合征（IBS）。胃食管反流病被定义为具有主要的反流症状，如今不被视为消化不良的一个亚组。消化不良分为几个亚组（溃疡样、动力障碍样、未分类，有时当反流症状与腹部不适同时出现时，为反流样消化不良）。然而，其临床相关性值得怀疑。如果消化不良症状伴有排便习惯紊乱，则该患者被称为患有肠易激综合征。在临床情况下，患者常常表现出症状重叠，且主要症状特征会不时变化。不同的定义使得患病率报告的可比性降低。文献中关于三个月期间胃食管反流病患病率的大致平均值为，10%的人群报告患有该病，25%的人群有总体反流症状，25%的人群有消化不良（无主要反流症状），15%的人群有不伴有反流症状的消化不良，15%的人群患有肠易激综合征。
