Hi there, Welcome to HCM, Please do not worry it does not seem like you have diabetes with the values that you are showing. . Your Body mass index based on the values you have given is in the normal range putting you at a lower risk for diabetes. Diabetes is more common in pregnancy in women who have had a family history of diabetes, diabetes in a previous pregnancy, history of polycystic ovaries, or if overweight, if you do not have any of the above factors you are at a lower risk for it. Diabetes can affect both the mother and the baby in pregnancy. It can cause excess weight gain of the baby making delivery difficult to achieve and more likely of a Caesarean. Also certain complications such as bleeding after delivery and chances of Admission to NICU of the baby increases. The baby needs to be monitored in the first few hours after birth for sugar levels and other complications, some may have breathing difficulties. But all these complications can be minimized by checking sugar levels regularly in the mother who is diagnosed to be diabetic in pregnancy, she may also be given insulin to control the sugars . So just repeat the glucose tolerance test at 26 weeks and if its normal do not worry. Hope this helps. Regards.
