Background: Gestational diabetes mellitus (GDM) and type 2 diabetes mellitus (T2DM) represent two different components of the spectrum of diabetes mellitus (DM). Women with GDM have a high chance of developing T2DM in later life and this relative risk depends on a number of factors including ethnicity. Aim: To compare and estimate the risk of developing T2DM in South Asian women with a history of GDM compared to those without a history of GDM. Methods: This is a systematic review of PubMed and MEDLINE articles reporting the progression of GDM to T2DM that were published in English from 2000 to 2020. We performed meta-analysis to calculate risk ratios (RR). Results: We selected 6 studies considering the inclusion and exclusion criteria after sorting 25 full-text articles. Of the 44165 South Asian women assessed, 3095 had GDM and 41070 were without GDM. 995 women in GDM group and 1525 women in non-GDM group had developed T2DM. The RR of women with GDM over non-GDM in developing T2DM was 10.81 (95% confidence interval (CI): 7.61–15.35) suggesting that women with GDM are at 10.81 times more risk of developing T2DM than non-GDM. The cumulative incidence of T2DM in GDM group was 17.34% at 5 years of follow-up and 33% at more than 10 years of follow-up. Conclusion: The risk of developing T2DM in later life is higher in South Asian women with GDM than without GDM. Therefore, lifestyle and pharmacological interventions, patient communication, timely screening, and long-term follow-up of GDM patients are important to reduce the risk.
