Abstract: As the country has loosened its family planning policy and living standards have improved, postnatal obesity has become a social problem seriously threatening public health in China, which has attracted widespread attention from all walks of life. Therefore, a method for improving postpartum obesity urgently needs to be explored. Intestinal microecology is critical to the health of mothers and children, and plays an important role in the occurrence and development of obesity. Improving intestinal microecology as an effective way to improve obesity has attracted more and more attention. This article focuses on the relationship between postnatal obesity and intestinal microecology and summarizes the mechanisms of action of probiotics and prebiotics in regulating intestinal microecology to suppress postpartum obesity. The purpose of this article is to provide a theoretical basis for probiotic-prebiotic intervention based on intestinal microecology to suppress postpartum obesity.
