Gestational Diabetes Management and Pregnancy Outcomes

Gestational diabetes mellitus (GDM) is characterised by glucose intolerance first detected during pregnancy and affects maternal and foetal health through mechanisms of insulin resistance and pancreatic β-cell dysfunction. Effective management spans dietary modification, tailored physical activity and pharmacological interventions such as insulin or metformin when lifestyle measures prove insufficient. Advances in continuous glucose monitoring have refined glycaemic control, while precision nutrition and multiomics approaches promise personalised therapeutic pathways. Maternal hyperglycaemia is associated with adverse outcomes including macrosomia, pre-eclampsia, preterm birth and neonatal hypoglycaemia. Long-term, women with GDM face heightened risks of type 2 diabetes and cardiovascular disease, and their offspring may encounter metabolic disorders across the life course. Global screening strategies continue to evolve, with debate over diagnostic thresholds and timing of oral glucose tolerance testing. Interdisciplinary care models that integrate endocrinology, obstetrics and dietetic support are fundamental to optimising perinatal outcomes and mitigating long-term sequelae for mother and child.

Research from Nature Portfolio

Recent studies have uncovered a placental role for insulin-like growth factor binding protein 1 (IGFBP1) in glycaemic regulation during pregnancy. Transcriptomic analysis of placental tissue revealed that higher IGFBP1 expression correlates with greater maternal insulin sensitivity at mid-gestation, and circulating protein assays demonstrated that low IGFBP1 levels in early pregnancy predict subsequent GDM. These findings implicate placental IGFBP1 deficiency in the pathogenesis of GDM and suggest its potential as a biomarker for early risk stratification and as a target for therapeutic modulation.

The graph below shows the total number of articles in gestational diabetes management and pregnancy outcomes across all publications each year (not limited to Nature Index journals).

Technical terms

Insulin resistance: Impaired cellular responsiveness to insulin resulting in elevated blood glucose levels.

Oral glucose tolerance test (OGTT): Diagnostic procedure in which plasma glucose is measured before and after ingestion of a glucose load to assess glycaemic control.

Macrosomia: Excessive foetal growth, typically defined as birth weight above the 90th percentile for gestational age.

Multiomics: Integrated analysis of diverse molecular datasets, including genomics, proteomics and metabolomics, to characterise biological systems.

Insulin-like growth factor binding protein 1 (IGFBP1): A placental protein that modulates insulin-like growth factor activity and influences maternal and foetal glucose metabolism.
