One of the tests all moms should go through during pregnancy is screening for diabetes. This is done through a blood test, typically between weeks 24 and 28 of pregnancy. The purpose is to know whether the mother's blood sugar level is abnormally high, which can indicate a diagnosis of gestational diabetes. Moms with gestational diabetes need treatment to get the best outcome for themselves and their babies. What if the blood sugar level is high but not high enough to be classified as gestational diabetes? The researchers in this new study found that such high blood sugar predicts that the baby is more likely to have childhood obesity by about 5-7 years of age. This suggests that the risk of childhood obesity can be lowered by helping mothers have a healthy body weight before they become pregnant, and by avoiding abnormally high blood sugar during pregnancy.
