Gastric Motility Disorders in Diabetic Patients
Summary
Diabetic gastroparesis affects a substantial proportion of individuals with long-standing type 1 or type 2 diabetes mellitus. Chronic hyperglycaemia leads to autonomic neuropathy, loss of interstitial cells of Cajal and remodelling of the gastric musculature, resulting in delayed gastric emptying and disrupted contractile patterns. Clinically, patients experience early satiety, nausea, vomiting and erratic glycaemic excursions that further impair motility. Diagnosis requires objective assessment of gastric emptying and motor function to exclude mechanical obstruction. Technological advances in non-invasive manometry, breath tests and imaging have refined the classification of motility disturbances, distinguishing gastroparesis from functional dyspepsia and other dysmotilities. Management integrates optimised glycaemic control, dietary modifications and prokinetic pharmacotherapy, yet many patients derive only partial relief. Emerging strategies targeting the pylorus, neuromodulation and inflammatory pathways promise more personalised interventions. A deeper understanding of molecular and immunological mechanisms is reshaping the therapeutic landscape and may yield novel biomarkers for early detection and tailored treatment.
Research from Nature Portfolio
Recent studies have consolidated diagnostic and classificatory frameworks for gastric motility disorders, offering standardised protocols for assessment of gastric emptying, slow-wave rhythm and antral contractility. High-resolution manometry coupled with breath-test guidelines now permits clear differentiation between fundic accommodation defects and pyloric dysfunction. These consensus recommendations enable stratification of diabetic patients by primary motor abnormality, guiding choice of endoscopic, pharmacological or neuromodulatory therapy. By harmonising definitions and methodologies, this work establishes a robust platform for multicentre trials of novel interventions in diabetic gastroparesis.

The graph below shows the total number of articles in gastric motility disorders in diabetic patients across all publications each year (not limited to Nature Index journals).
Technical terms
Gastroparesis: A disorder characterised by delayed gastric emptying in the absence of mechanical obstruction, leading to symptoms such as nausea, vomiting and early satiety.
Interstitial cells of Cajal (ICC): Specialized mesenchymal cells that generate electrical slow waves and mediate neuromuscular communication in the gastrointestinal tract.
Gastric emptying scintigraphy: A diagnostic imaging technique that quantifies the rate at which a radiolabelled meal exits the stomach.
Prokinetic agent: A class of medication that enhances gastrointestinal motility by stimulating smooth muscle contractions or modulating enteric neurotransmission.
Vagal nerve stimulation: A neuromodulation approach involving electrical stimulation of the vagus nerve to influence gastric motility and autonomic function.
