Positive effects of acupuncture and electroacupuncture were observed in regulating gastric motility, gastric accommodation, mental status, gastrointestinal hormones, and central and autonomic functions while improving dyspeptic symptoms and quality of life.
In this systematic review, we pooled randomized controlled trials with mechanistic investigations of acupuncture or electroacupuncture in improving dyspeptic symptoms, and illustrated the existing results that may provide potential explanations for the therapeutic effects. The findings of included studies in this review suggest that acupuncture and electroacupuncture can improve gastric motility and accommodation, regulate gastrointestinal hormones and mental status, and alter certain central and autonomic functions in patients with functional dyspepsia. However, due to limitations in the included articles, high-quality studies with well-planned designs and multiregional investigations are necessary to provide more convincing and credible evidence.
