Can Medical Nutrition Therapy Affect Feto-Maternal Outcomes in Gestational Glucose Intolerance: An Open-Label Pilot Randomized Control Trial in World's Diabetes Capital.

INTRODUCTION: Gestational diabetes is defined as the carbohydrate intolerance of variable severity with onset or first recognition during pregnancy. Gestational glucose intolerance (GGI) is used to indicate pregnant women whose 2-h postprandial glucose is > 120 mg/dl and below 140 mg/dl (Diabetes in Pregnancy Study Group of India, DIPSI criteria).

AIM: This study was planned to see whether intervention in GGI group helps to improve feto-maternal outcomes.

METHODOLOGY: This open-label randomized control trial was conducted in Department of Obstetrics and Gynaecology of King George's Medical University, Lucknow. Inclusion criteria were all the antenatal women attending the antenatal clinic and diagnosed as GGI, and exclusion criteria were overt diabetes.

RESULTS: Total of 1866 antenatal women were screened, and among them, 220 (11.8%) women were diagnosed as gestational diabetes; 412 (22.1%) women were diagnosed as GGI. The mean fasting blood sugars in the women with GGI who had medical nutrition therapy were much lower than the women with GGI who did not have any intervention. The present study showed the women with GGI had higher complications like polyhydramnios, PPROM, foetal growth restriction, macrosomia, preeclampsia, preterm labour and vaginal candidiasis more in the women with GGI as compared to euglycaemic women.

CONCLUSION: The present study of nutritional intervention in GGI group has shown trend towards lesser complication if we start medical nutrition therapy reflected by delayed development of GDM and less neonatal hypoglycaemia and hyperbilirubinemia.
