About the trial

What the trial wants to find out

Gestational diabetes mellitus (GDM) is becoming more common globally as a metabolic disease that occurs during pregnancy and influences the mother and the fetus. It has been linked to preeclampsia, C-section, and a higher lifetime risk of developing type 2 diabetes both for mother and the child. Another complication of GDM is dyslipidemia that also accentuates cardiovascular risks, so the care of lipid profiles is essential for the best pregnancy outcomes. The previous literature review indicates that micronutrients including vitamin D and calcium have a bearing on glucose and lipid profiles. Various studies have established that vitamin D improves the insulin response and lipid profile whereas calcium is vital in insulin and glucose homeostasis. Furthermore, it is revealed that calcium induces vitamin D so that it could undergo its full metabolic effect. Hence, the addition of vitamin D and calcium together may enhance glycemic management and lipid profiles of GDM patients. The aim of the present work is to compare the impact of vitamin D and calcium supplementation on lipid profiles and hyperglycemia in GDM patients. It will measure the major metabolic indices fasting plasma glucose, glycated hemoglobin (HbA1c) and lipid profile (LDL, HDL triglycerides) and review the effect of this on pregnancy outcomes. These outcomes will be assessed by a randomized-controlled trial.
