This paper examines the risks and complications that diabetes — particularly type 1 diabetes — poses during pregnancy, for both mother and child. It covers how insulin resistance during pregnancy elevates blood sugar, leading to complications such as fetal macrosomia, congenital malformations, respiratory problems, and infant mortality. The paper also addresses maternal health risks including toxemia and hydramnios. It then outlines preventive strategies, including preconception counseling, glycosylated hemoglobin testing, blood glucose monitoring, and the formation of a specialized medical team to help diabetic women achieve outcomes comparable to those of non-diabetic pregnancies.

Pregnancy requires more insulin in the body than normal because of the increased production of hormones that can lead to insulin resistance. For a woman suffering from type 1 diabetes, this is especially problematic because she already has difficulty producing or responding to insulin. Not only is the mother's health at risk, but the baby's health may suffer as well. As insufficient insulin causes blood sugar to rise in the mother, the sugar travels across the placenta to the baby. When the baby's blood sugar is high, the baby produces extra insulin to keep its own blood sugar normal. Problems of the developing baby may include larger or smaller size, increased risk for malformations or birth defects, or death in-utero. Fortunately, there are several precautions that a woman can take to dramatically decrease the risk of these complications.
Large and small birth-weight babies are a significant problem in the deliveries of diabetic mothers. Smaller than usual size typically occurs when the mother has had diabetes for several years and has developed changes in her blood vessels. On the other hand, the combination of high blood sugar and high insulin can cause the baby to grow larger than normal. Large birth weight, known as fetal macrosomia, occurs two to three times more often in diabetic pregnancies than in the general population. Risks of fetal macrosomia include:
Due to the increased risk of fetal macrosomia, women with diabetes are three to four times more likely to deliver by cesarean section.
If a diabetic woman does not receive preconception care to regulate blood sugar levels, the rate of major congenital malformations in women with preexisting diabetes is ten percent, compared to zero to five percent for women who receive preconception care. Other birth defects frequently associated with diabetes include eye defects, respiratory tract defects, cleft palate, anal atresia/stenosis, hypospadias, urinary tract defects, and positional defects of the foot. The most common birth defects involve damage to the heart and central nervous system.
