The interest in studying the microbial gut like probiotics has increased because it may play a significant role in reducing the risk of certain health conditions and promote overall health. In the recent decade, the nutritional researches have linked between having a regular healthy diet and the health conditions during pregnancy. For example, during the pregnancy period, women may counter several health conditions, such as Gestational Diabetes Mellitus (GDM) level. In this relation, a few recent researches have suggested that having a rich diet with a probiotics/prebiotic may reduce the incidence of GDM. Therefore, in the world market, the interest in studying the correlation between probiotics/prebiotics and the incidence of pregnancy health conditions has increased. This paper has been designed to review the recent studies that investigated the relationship between a rich diet with probiotics/prebiotics and the gestational health conditions.
