Functional dyspepsia is a common chronic gastrointestinal condition characterized by chronic upper gastrointestinal symptoms like indigestion, discomfort, early satiety, and bloating without structural abnormalities. It has a substantial impact on quality of life. The underlying causes can include GERD, peptic ulcer disease, infections, lactose intolerance, medications, and functional (non-ulcer) dyspepsia. Treatment options include acid suppressants, prokinetics, Helicobacter pylori eradication in infected patients, and complementary and alternative therapies. Empirical treatment is justified in typical cases without alarm symptoms, and treatment should be tailored based on the patient's most bothersome symptom.
