Insulin injections will not affect the normal course of pregnancy because insulin is safer for lowering blood glucose. In addition to the use of insulin to control blood glucose before pregnancy, insulin can also be used to lower blood glucose treatment after pregnancy. The use of insulin is safer for both the pregnant woman and the fetus. If a diabetic’s basal blood glucose is high it is difficult to get pregnant, and the drop in blood glucose level after using insulin to lower blood glucose treatment will also significantly increase the likelihood of pregnancy. So insulin control of blood sugar is a safer way to lower blood sugar before, during or after pregnancy.
