High blood sugar during pregnancy, also known as gestational diabetes, is a condition of elevated blood sugar that occurs during pregnancy and usually disappears after delivery. During pregnancy, hormones secreted from the placenta may increase your body’s resistance to insulin. This condition may cause your blood sugar levels to rise. High blood sugar during pregnancy applies to those who did not have diabetes before pregnancy. Those who had diabetes before pregnancy should maintain control of their existing diabetes during pregnancy. High blood sugar during pregnancy may occur at any stage of pregnancy, but it is usually seen in the second trimester (14–26 weeks).
