Narrative review explores interventions to improve glycemic outcomes in gestational diabetes, suggesting further research is needed.

This review aims to assess the impact of various lifestyle interventions on pregnancy outcomes related to gestational diabetes mellitus (GDM).
Conducted as a narrative review with search conducted on PubMed/MEDLINE, CINAHL, and Scopus.
Evaluated intervention studies focused on nutrition, physical activity, or a combination targeting GDM incidence, insulin use, or glycemic outcomes.
Included 43 studies primarily comprised of randomized controlled trials (RCTs).
Combined lifestyle interventions showed the most consistent improvements in glycemic control.
Mediterranean, low-glycemic index, and DASH diets were effective in managing GDM when paired with prenatal exercises.
Reporting on insulin outcomes was limited, highlighting a need for better reporting in future studies.

Altahan et al. (2026) studied this question.
