Functional dyspepsia (FD) is among the most established and common functional gastrointestinal disorders (FGIDs). FD is subdivided into two subtypes based on symptoms: epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS).

Based on international guidelines (Asian Consensus and Rome Consensus), a prokinetic, medication which promotes gut movement (such as Itopride) should be the 1st line treatment for the PDS sub-type and a proton pump inhibitor, medication which reduces stomach acid production (such as Esomeprazole) should be the 1st line treatment for the EPS sub-type.

However, in the routine practice in Malaysia, proton pump inhibitor is still commonly used as 1st line treatment for FD, regardless of subtypes. This may be one of the reasons why FD continues to be inadequately treated locally and causes poor health-related quality of life (QOL) in FD patients.

The purpose of this study is to compare the clinical symptoms and quality of life improvement in patients with functional dyspepsia (FD) after treatment according to international guidelines versus treatment according to routine practice. Adverse effects when managed according to guidelines versus routine practice will also be evaluated.
