Auricular Stimulation for Functional Dyspepsia With Insomnia: Efficacy and Mechanisms

Summary

Functional dyspepsia (FD) is a chronic disorder of gut-brain interaction characterized by bothersome upper abdominal symptoms arising from the gastroduodenal region. Diagnosis is made after clinical evaluation has excluded structural disease that could explain symptoms (e.g., upper gastrointestinal endoscopy). According to Rome IV criteria, FD is categorized into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS), with symptom overlap commonly observed. FD is prevalent worldwide and is associated with substantial impairment in health-related quality of life and a significant socioeconomic burden.

Sleep disturbance, anxiety, and depression are frequent in FD and are associated with symptom severity and recurrence. Current management-such as prokinetic agents, acid-suppressive therapy, and psychotropic medications when indicated-can be limited by variable efficacy, adverse effects, and concerns regarding long-term use. The pathophysiology of FD is multifactorial and incompletely understood; increasing evidence highlights dysregulation of the brain-gut axis and autonomic nervous system function (12,13). Auricular vagus nerve-related stimulation may influence brainstem neurotransmission, gastric tone/motility, and mood (14), suggesting a potentially safe, non-pharmacological approach for FD with comorbid sleep problems. However, the mechanistic links among autonomic regulation, gut microbiota/short-chain fatty acids, and FD remain uncertain.

This study aims to evaluate the clinical efficacy and safety of auricular acupoint stimulation in FD patients with sleep disorders and to explore underlying mechanisms using brain-function assessments together with autonomic and gastrointestinal-related measures.

Interventions

BEHAVIORAL

Auricular acupressure in concha area

The method of pressing beans on auricular points is based on the meridian theory and viscera theory in the basic theory of traditional Chinese medicine, combined with the knowledge of modern medical anatomy, and from the perspective of syndrome differentiation and treatment, relevant auricular points are selected, and appropriate stimulation such as kneading, pressing, pinching and pressing is given to the seeds of Vaccaria seed attached to the concha auricularis, so that the auricular points can produce acid, numbness, swelling and pain slowly and continuously. For therapeutic purposes.

BEHAVIORAL

Auricular acupressure in earlobe

The auricular point pressing bean method is based on the meridian theory and viscera theory in the basic theory of traditional Chinese medicine, combined with the knowledge of modern medical anatomy, and from the perspective of syndrome differentiation and treatment, the relevant auricular points are selected, and the seeds attached to the ear lobe, which is the least innervated part of vagus nerve, are given appropriate stimulation such as kneading, pressing, pinching and pressing, so that the auricular points produce acid, numbness, swelling and pain slowly and continuously. For therapeutic purposes.
