Gestational diabetes mellitus (GDM) is a common complication of pregnancy that can lead to negative maternal and fetal outcomes.  Online support interventions have been suggested as a potential tool to improve the management of GDM.This systematic review aimed to summarize the effectiveness of social media and online supports interventions for the management of GDM.We conducted a thorough systematic search across Web of Science, Scopus, and PubMed, following PRISMA guidelines, and supplemented it with a manual search.  Our results included both qualitive and quantitative research.  We rigorously assessed quantitative studies for bias using ROBINS-I and RoB 2 tools, ensuring the reliability of our findings.We incorporated a total of 22 studies, which were compromised or ten qualitative and twelve quantitative studies.  Online support interventions were found to have a positive impact on promoting self-care and improving healthcare outcomes for women with GDM.  Individualized diet and exercise interventions resulted in lower odds of weight gain and GDM diagnosis, while online prenatal education increased breastfeeding rates.  In addition, telemedicine options reduced the need for in-person clinical visits and improved patient satisfaction. Online support interventions show potential to improve clinical outcomes in patients with GDM in this small literature review.  Future research is also necessary to determine the effectiveness of different types of online interventions and identify strategies to improve engagement and the quality of the information provided through online resources.
