During pregnancy, if a pregnant woman suffers from high blood glucose, it can potentially impact the fetus's growth and development. After the baby is born, this may result in a larger size of the fetus, and a decrease in the baby's immune system, making them more susceptible to infectious diseases. If high blood glucose occurs during pregnancy, it is important to control the diet promptly, eat less sugary food, and also control the portion of food. If necessary, medical treatment under the guidance of a doctor can also be conducted to maintain blood glucose at a stable level. If blood glucose is well-controlled during pregnancy, the baby will be just like other healthy babies after birth.
