Background: A metabolic condition known as gestational diabetes mellitus (GDM) is characterized by varying degrees of glucose intolerance that is initially identified during pregnancy and is likely to go away when the pregnancy is over. The present study was conducted to evaluate foetomaternal outcomes in women with gestational diabetes mellitus. Materials & Methods: 86 pregnant women with gestational diabetes mellituswere screened for universal screening for GDM using a 2-h 75 g OGTT. In this screening test, 75 g oral anhydrous glucose was given and then after 2 h, the blood glucose level was measured. If this level is more than 140 mg/dl then it is considered as screening and diagnostic of GDM. The OGTT test was repeated for the patient who had a negative result on screening test but had at least one risk factor for GDM at 32–36 weeks of gestation. Results: Parity was Primi in 40, 2nd gravida in 24, and 3rd gravida in 22. BMI <18 kg/m2 was seen in 12, 18-24.9 kg/m2 in 28, and >25 kg/m2 in 46 patients. The difference was non- significant (P> 0.05). The mode of delivery was cesarean in 49 and vaginal in 37 cases. Complications found were hypoglycemia in 4, hyperbilirubinemia in 2, and transient tachypnoea in 7 patients. The difference was significant (P< 0.05). Maternal complications were APH in 3, PPH in 8, PIH in 25 and pre- term labor in 6 cases. The difference was significant (P< 0.05). Conclusion: Given the rising incidence of GDM risk factors, pregnant women with GDM are likely to experience negative consequences. Prenatal GDM screening is essential for early detection and treatment during the antennal visit, which will enhance the outcomes for both the mother and the fetus. Women who have GDM can avoid developing diabetes mellitus in the future.
