Core Tip

Core Tip: Pregnancy is a complicated physiological process, with interactions between pregnancy hormones, the immune system, metabolism and gut microbiota. The dysregulation between these systems can cause pregnancy-specific diseases, including pregnancy-specific gastrointestinal diseases. Here we summarize the current opinions on dysbiosis associated with pregnancy-related gastrointestinal diseases including pre-eclampsia, intrahepatic cholestasis of pregnancy, hyperemesis gravidarum and constipation. The composition of gut microbiota changes dramatically during these diseases.
