Thyroxine is very important during pregnancy. If the thyroxine function is low, people will usually show apathy and depression, and children will be stunted if they are deficient in thyroxine, and neurodevelopmental problems will also occur in children if the pregnant woman’s thyroid function is not normal. The above problems can be overcome by oral thyroxine sodium tablets, after taking the drug to maintain the thyroid function at normal levels, through the blood to monitor the amount of medication is not appropriate to eat more drugs to eat into hyperthyroidism that is certainly not good, the drug is not enough to eat may also cause hypothyroidism, as long as the control to the normal value will not have an impact. If the thyroxine level is normal during pregnancy, it will have no effect on the baby’s development, and the baby can be born as usual. Many of our patients get married and have children after surgery, so monitoring thyroid function so that it reaches normal values is fine, and having had surgery doesn’t have much effect.
