Objective: The purpose of this study was to see how food organization and Metformin affected placental morphology in women with GDM.
 Methods: 66 GDMs were registered after providing informed consent permission. 35 patients of GDM through blood sugar levels 140 mg/dl remained allocated Set B (2500-3000Kcal/day and 30-minute walk three times a week). They remained reserved on diet control, while 34 patients of GDM through blood sugar levels >140 mg/dl have been delegated Set C and remained reserved on diet with tablet Metformin (550mg TDS). Lastly, 28 healthy pregnant women remained retained in Set A as controls. Placentas were stored and analyzed for morphology after delivery.
 Results: Heavy placentae thru extensive villous immature, charangoists, and syncytial knots were observed in set B, while fibrinoid necrosis and calcification were observed in set C. Placental and cord width were significant in Set B against A, but only cord width was relevant in Set C against A in gross morphology. In light microscopy, charangoists, infarction, and syncytial loops showed detected in sample 2 against with a villous maturity; moreover, charangoists and syncytial knots have been found in appendix B versus C placental width, but C versus A results were negligible.
 Conclusion: In comparison to the diet group, metformin exhibited beneficial benefits on placental morphology that were equivalent to normal controls.
