In conclusion glycemic control in pregnant diabetic females and fetal outcome had intimate relation to each other. It is useful in modulation of fetal out come as regards to the fetal weight, congenital anomalies, fetal mortality, the need for NICU admission, neonatal jaundice. In our study we had patients in their third trimester presenting to us with gestational diabetes, or pregestational diabetes, either in good control or intermediate or poor controlled state. We tried to adjust the glycemic states as much as possible, however that was hard enough in poorly controlled patients. So the net result from this study that glycemic control started as early as possible (the best being preconceptional) is important to decrease the incidence of congenital anomalies, fetal weight, fetal mortality, the need for NICU admission and neonatal jaundice.
