A high thyroid gland in newborns is generally considered to be “hypothyroidism”, which refers to hypothyroidism. It is very common in infants and children and can have a significant impact on their intelligence, causing mental retardation and lack of self-care. To be precise, hypothyroidism refers to a higher than normal level of thyroxine, resulting in low thyroid function. The main manifestation of this condition is that the child’s intelligence and bones are severely affected, and it can have a great impact on the child’s future life. It is an extremely serious disease that requires a long period of treatment to recover and may lead to lifelong medication that cannot be cured. The main cause of this disease is the lack of iodine in the newborn, which may be caused by the lack of iodine in the mother’s body and the lack of iodine supplementation during pregnancy. It is recommended to include more iodized salt in the daily diet. In general, the treatment of this condition requires a long term attack. At present, there is no surgical treatment, only medication. The only treatment available is medication, which has a great impact on the daily life of the patient and adds to the financial burden of the family when taking medication for a long time.
