Mistakes in dyspepsia and how to avoid them
Expert knowledge at your fingertips!
Dyspepsia refers to upper abdominal discomfort that is thought to arise from the upper gastrointestinal tract. Symptoms include epigastric pain or discomfort, bloating, early satiety and/or fullness after meals, repeated belching or regurgitation (often rumination), nausea and heartburn.1 The symptoms of dyspepsia are nonspecific, but most commonly result from one of four underlying disorders: functional (nonulcer) dyspepsia, gastro-oesophageal reflux disease (GORD; 10–20% erosive esophagitis), peptic ulcer disease (5–15%) and malignancy (~1%).2 Dyspeptic symptoms may also result from other problems, such as medication intolerance, pancreatitis, biliary tract disease or motility disorders (e.g. gastroparesis or gastric dumping).Clinical guidelines recommend that endoscopy is not always required for diagnosis; a positive diagnosis of GORD and functional dyspepsia can be based on clinical presentation in the absence of alarm symptoms or features (see below).3,4 In many cases symptoms are increased after meal ingestion (postprandial distress syndrome), being triggered by impaired gastric accommodation and visceral hypersensitivity to gastric distension.5 Other patients have an epigastric pain syndrome in which discomfort is independent of food intake and gastrointestinal function.6 There is an important overlap between functional dyspepsia and other functional gastrointestinal diseases (e.g. irritable bowel syndrome [IBS]) and chronic pain syndromes (e.g. fibromyalgia).7 Psychological disease (e.g. anxiety or somatization disorder) and/or psychosocial stress are also present in a significant proportion of patients who seek medical attention.8,9 Notwithstanding the constructive advice provided by published reviews and guidelines, the broad definition of dyspepsia, lack of diagnostic investigations, uncertain cause of disease, psychosocial issues and paucity of specific treatments make the management of dyspepsia challenging. Here, I discuss 10 common and/or high-impact mistakes that are made in the diagnosis and treatment of patients with dyspeptic symptoms: five related to diagnosis, five related to treatment.
