Overlap Functional GI Disorders: FD-GERD (Epigastric Pain, Postprandial Fullness, Belching & Acid Eructation)

About one third of patients qualifying for Rome criteria for functional dyspepsia (FD), but without the typical reflux symptoms of heartburn and acid regurgitation were found on 24-hour ambulatory esophageal pH monitoring to have pathologic acid reflux, with epigastric burning sensation. The putative pathophysiology of this FD-GERD overlap may include impaired gastric accommodation with transient lower esophageal sphincter relaxations (TLESRs), duodenal eosinophilia and duodenal hypersensitivity. Then, possible treatment options may include histamine H1/H2 receptor blockade, anti-secretory agents such as PPI or P-CAB, neuromodulators such as tricyclic agent and fundus relaxant such as baclofen, acotiamide, etc.
