Gastric Autonomic Neuropathy in Diabetes

Year: 2025

Type: article

Abstract: Autonomic dysfunction of the stomach typically manifests as delayed gastric emptying or gastroparesis and is seen in individuals with both type 1 and 2 diabetes. However, impaired gastric motility is only modestly associated with the presence of upper gastrointestinal symptoms, and the diagnosis of gastroparesis essentially requires a formal measurement of gastric emptying, ideally employing a sensitive and precise technique such as scintigraphy. There is a bidirectional relationship between gastric emptying and glycemia: insulin-induced hypoglycemia accelerates, while acute elevations in blood glucose may delay gastric emptying. On the other hand, relatively more rapid emptying is associated with a higher initial rise in postprandial glucose. The management of gastroparesis requires an individualized approach, integrating dietary modifications, nutritional supplementation, pharmacological therapies, and, in severe cases, advanced interventions including gastrojejunostomy and gastric electrical stimulation. This review provides an overview of the pathophysiology and diagnosis of autonomic neuropathy of the diabetic stomach and discusses current clinical management strategies.
