what type of diabetes can a unborn baby develop?
High blood sugar can affect you and your unborn baby. Pregnant women with high blood sugar are more likely to: 1  Have a baby with birth defects, if blood sugar is not in control during the first two months of pregnancy (in women with type 1 or type 2 diabetes).
Gestational diabetes happens when you have too much sugar (glucose) in your blood during pregnancy. Your blood sugar levels can go up when your body isn't producing enough of a hormone called insulin. Insulin helps: While you're expecting, your body has to make extra insulin, especially from mid-pregnancy onwards.
