A Review on Gestational Diabetes Mellitus: Current Knowledge and Challenges

Abstract

Medical nutritional therapy (MNT) is the cornerstone of GDM management, emphasizing a balanced macronutrient intake to maintain normoglycemia and prevent excessive weight gain in both mother and fetus. Nutritional guidelines recommend a diet with a low glycemic index, adequate fiber, and controlled carbohydrate intake to moderate postprandial glucose levels. Glucose intolerance, which was initially identified during pregnancy, is the hallmark of gestational diabetes mellitus (GDM), a growing public health concern, and individualized nutritional interventions are essential for optimizing maternal and fetal outcomes. Furthermore, dietary supplements such vitamin D3, myoinositol, and omega-3 fatty acids have demonstrated promise in enhancing metabolic balance and lowering the risk of negative effects. Pregnancy glucose intolerance may be made worse by insulin resistance, chronic inflammation, and hormonal abnormalities linked to polycystic ovarian syndrome (PCOS). Poor outcomes for mothers and newborns may result from PCOS and GDM co-occurring, however the effects are unclear and the data is still contradictory. The primary objectives of preventative strategies include early identification of high-risk individuals, lifestyle change, and weight control prior to conception. To lower the risk of long-term consequences like cardiovascular disease, GDM patients must manage comorbidities including hypertension and dyslipidemia. Beyond probiotics, novel approaches to gut microbiota regulation have surfaced as promising means of enhancing insulin sensitivity and lowering inflammation linked to GDM, such as dietary interventions high in fiber and polyphenols. A comprehensive, evidence-based strategy to nutritional therapy can improve metabolic control in GDM and lower long-term health concerns for women and their offspring.
