Functional dyspepsia (FD) is a common disorder in East and Southeast Asia where subjects experience post prandial fullness/bloating, early satiety, belching, epigastric pain, and/or burning. A subset of patients with FD experience triggers exclusively related to meals, defined as the post prandial distress syndrome in the Rome IV guidelines. There is significant overlap of symptoms and implicated pathogenic factors with another common functional gastrointestinal disorder, irritable bowel syndrome (IBS) and in fact, a significant proportion of subjects have FD/IBS overlap. The introduction of the low-FODMAP diet has changed the paradigm of treatment for IBS. Like IBS, dietary management appears to be important to patients with FD and clinicians treating the condition. This review aims to examine the current role of diet in the management of FD in East and Southeast Asia, with an exploration of the likely efficacy and mechanisms of action of the low-FODMAP diet in this region.
