Gestational diabetes and the risk of type 2 diabetes in postnatal period

Abstract

Gestational Diabetes Mellitus (GDM) is the most common pregnancy complication, affecting 14% of global pregnan- cies. This literature review emphasizes the importance of developing universal screening and diagnostic criteria in pregnancy. Screening criteria, as outlined by organizations like NICE and WHO, vary, reflecting the ongoing debate about the most effective diagnostic methods. GDM is linked with significant risk factors, and timely diagnosis enables intervention strategies to prevent adverse obstetric outcomes. This review underscores the lasting impact of GDM on maternal health, increasing the risk of Type 2 Diabetes (T2D), particularly in the first five years post-delivery. Despite this risk, there is a notable gap in preventive care and postnatal screening. Barriers include the absence of a universal protocol, unclear responsibilities among healthcare professionals, and challenges faced by women in the postnatal period. The low uptake of postnatal testing increases potential risks of entering a future pregnancy with undiagnosed type 2 diabetes. This review highlights the urgent need for effective postpartum interventions, emphasizing education for women to prevent type 2 diabetes and ensuring safe subsequent pregnancies. There is a need for comprehensive, universal postnatal care strategies to address the increasing prevalence of type 2 diabetes globally.
