Previous studies had shown that the gut microbiota of polycystic ovary syndrome (PCOS) patients had significant differences from those of healthy individuals, which may play an important role in the pathogenesis of PCOS. Lifestyle intervention, such as nutritional intervention, could improve the metabolic profiles and PCOS-like phenotypes of PCOS patients. Meanwhile, nutritional intervention could rapidly alter and reshape the distribution of gut microbiota in individuals. Therefore, we sought to investigate the differences in gut microbiota in overweight and obese PCOS patients with or without nutritional intervention. Thirty-six overweight and obese PCOS patients were finally enrolled in the study. Eighteen individuals who refused nutritional intervention (RNI) were collected as the RNI group. Eighteen individuals who received the nutritional intervention were collected as the pre-NI group before the nutritional intervention. And they were also collected as the NI group after the nutritional intervention for 4-12 weeks. Significant decreases in BMI, FBG, TC, TG, APO A1, and APO B were observed when comparing the NI group with the pre-NI and RNI groups after the nutritional intervention for 4-12 weeks. Meanwhile, the differences in the phylum Firmicutes, Bacteroidetes, and the species Eubacterium rectale, Flavonifractor plautii, and Bacteroides vulgatus between the NI and the RNI groups were observed, which may be potentially linked to the improved inflammatory state and PCOS-like phenotypes of overweight and obese PCOS individuals.
