New Framework Clarifies Five Distinct Stomach Disorders Often Confused in Clinics
Researchers have formally categorized gastroduodenal disorders into five distinct conditions—from functional dyspepsia to a newly recognized inability-to-belch syndrome—offering clinicians a standardized diagnostic roadmap. The classification could reduce misdiagnosis, improve treatment targeting, and lower unnecessary healthcare spending on patients receiving wrong therapies.

Symptoms that can be attributed to the gastroduodenal area are classified into 5 categories: (1) functional dyspepsia, with 2 subcategories that can overlap: postprandial distress syndrome, with meal-induced symptoms of postprandial fullness or early satiation and epigastric pain syndrome, with epigastric pain or burning that does not occur exclusively postprandially; (2) nausea and vomiting disorders, which include 3 subcategories: chronic nausea vomiting syndrome; cyclic vomiting syndrome; and cannabinoid hyperemesis syndrome; (3) excessive belching disorders, defined as audible escapes of air from the esophagus or the stomach and classified into 2 subcategories depending on the origin of the refluxed gas: gastric or supragastric belching; (4) inability to belch syndrome, a new category defined by the self-reported inability to belch; and (5) rumination syndrome, defined by the repetitive, effortless regurgitation of recently ingested food into the mouth, followed by the reswallowing or expulsion of the food bolus.
