Pregnant women develop increased insulin resistance during the second and third trimesters.Insulin never crosses the placenta; the fetus starts making its own around the 10th week.As a result of normal metabolic changes during pregnancy,insulin-dependent women are prone to hypoglycemia (low levels).Maternal insulin requirements may double or quadruple by the end of pregnancy.
