Gestational diabetes mellitus (GDM) is a condition of glucose intolerance first recognized during pregnancy, affecting approximately 14% of pregnancies worldwide. It carries risks for both mother and offspring, including increased likelihood of developing type 2 diabetes postpartum.

Microbiome Associations

Emerging research indicates significant gut microbiome alterations in GDM, including both bacterial and fungal dysbiosis (, ). Microbiome-derived metabolites may contribute to insulin resistance mechanisms ().

05
Taxonomic Analysis

Enrichment of bacteroides and depletion of faecalibacterium prausnitzii observed across multiple studies (, ). Fungal dysbiosis—particularly shifts in Candida and Saccharomyces—is a distinctive feature ().

Microbiome Associations#

Emerging research indicates significant Gut Microbiome alterations in GDM, including both bacterial and fungal Dysbiosis ([1]Fungal Dysbiosis 2023 — Gut Fungal Communities in Gestational DiabetesVarious · 2023Open reference 1 ↓[2]Wang 2026 — Intestinal Fungal Dysbiosis in Gestational Diabetes Mellitus Associated with Adverse Pregnancy OutcomesWenxin Wang, Sha Lu, Yuanqing Fu et al. · 2026Open reference 2 ↓). Microbiome-derived metabolites may contribute to insulin resistance mechanisms ([3]Susarla 2024 — Microbiome-Derived Metabolites in Early to Mid-Pregnancy and Risk of Gestational DiabetesSita Manasa Susarla, Oliver Fiehn, Ines Thiele et al. · 2024Open reference 3 ↓).

Associated Conditions#

GDM shares microbial and metabolic patterns with Type 2 Diabetes, Polycystic Ovary Syndrome, and Obesity. Women with GDM have significantly elevated risk of developing type 2 diabetes later in life.

Open Questions#

Unresolved questions identified by the current evidence record.

01What specific metal dysregulation patterns characterize GDM distinct from T2D?

The current WikiBiome record identifies this as an unresolved evidence gap.

02Does gestational fungal dysbiosis persist postpartum and influence T2D conversion?

The current WikiBiome record identifies this as an unresolved evidence gap.

03Can microbiome-targeted interventions during pregnancy prevent GDM onset?

The current WikiBiome record identifies this as an unresolved evidence gap.
