Background and Objectives: The enteric nervous system (ENS) dominates the onset of obesity and has been shown to regulate nutrient absorption and energy metabolism. Methods and Study Design: This study was performed to investigate the role of electroacupuncture in regulating ENS function in obese mice. Obese mice were obtained by highfat diet. 16S rRNA pyrosequencing, Western blotting, quantitative PCR, and neurotransmitter analysis were used for this purpose. Results: Body weight, Lee index, serum lipid, leptin, and adiponectin levels, and other basic indices were significantly ameliorated after electroacupuncture intervention. The pathological ENS scores, serum neurotransmitter levels, and intestinal transit rate were markedly changed in obese mice. Moreover, electroacupuncture promoted the diversity of gut microbiota. No significant differences were observed 21 and 28 days after electroacupuncture. Conclusions: These results suggested ENS may be a new treatment approach to obesity.
