AbstractDiabetic gastroparesis carries a heavy burden on people with diabetes and the healthcare system. It remains underdiagnosed and represents challenges to treat. This article reviews the epidemiology, pathophysiology, clinical features, diagnosis and treatment of diabetic gastroparesis. The disorder is characterized by delayed gastric emptying without evidence of mechanical gastric outflow obstruction. It presents with upper gastrointestinal (GI) symptoms such as nausea, vomiting, early satiety, postprandial fullness, upper abdominal discomfort and or bloating. As the prevalence of diabetes has been growing over the last few decades, we would expect an increased incidence of delayed gastric emptying in poorly controlled diabetes and perhaps in line with the increasing use of medications that act on the GI tract such as incretin-based therapy. The disease results from multiple reversible and irreversible mechanisms. Diagnosing diabetic gastroparesis requires careful history, examination and investigations to exclude other disorders that could mimic its clinical presentation. Treatment involves a wide variety of options starting with optimization of glycaemic control, stopping any offending medications and lifestyle modifications followed by the introduction of medical therapeutics such as prokinetics. Then, surgical interventions are considered in refractory cases.© 2022. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
