Question

Quizplus · Accepted Answer

Pregnant women develop increased insulin resistance during the second and third trimesters.Pregnancy exerts a diabetogenic effect on the maternal metabolic status during the latter part of second and third trimesters.Insulin never crosses the placenta;the fetus starts making its own insulin around the tenth week.As a result of normal metabolic changes during pregnancy,insulin-dependent women are prone to hypoglycemia.Maternal insulin requirements may double or quadruple by the end of pregnancy.
