For the fetus, the long-term hyperglycemic environment slows down its lung maturation and increases the risk of respiratory distress, lung infection and hypoglycemia after birth, which need to be controlled by early treatment. Low thyroid hormone levels (hypothyroidism) may affect fetal intelligence and bone development and risk cretinism in severe cases; high thyroid hormone levels (hyperthyroidism) may lead to miscarriage in early pregnancy and mood swings of the pregnant mother. It is worth noting that, according to the current medical level, folic acid supplementation during the first 3-6 months of pregnancy can effectively reduce the possibility of fetal malformations, while the couple should pay attention to rest, maintain a relaxed state of mind, quit smoking, alcohol and psychotropic drugs, and reduce exposure to X-rays and radiation, all of which can help to have a healthy baby.
