    Clinical features

    Epigastric pain or discomfort following meals, often accompanied by bloating, sensation of fullness and nausea. Dyspepsia is most commonly functional. The diagnosis of functional dyspepsia is based on clinical assessment after ruling out organic causes (Gastro-oesophageal reflux, Gastric and duodenal ulcers, drug-induced symptoms, gastric cancer). If possible, test for Helicobacter pylori.


    In adults:



    Note: consider and treat possible intestinal parasites (see Intestinal protozoan infections, CestodesNematode infections, Chapter 6; Amoebiasis, Chapter 3).
