Another blood sample will also be taken for additional testing. If the thyroid gland is normal, a test to check the pituitary gland is done. Since thyroid hormone is essential for normal bone growth, an X-ray of the baby's knee may also be taken. With the X-ray, the doctor can tell if the growth of the bones has been normal, or if it has been delayed. This information helps the doctor to anticipate any future problems.
Hypothyroidism is treated with medication, in tablet form, as prescribed by the doctor.
For newborns, the tablet may be crushed, mixed with a liquid and given to the baby with a medicine dropper. Once the child starts eating solid foods, the medication may be mixed with fruit or cereal, on a spoon. This simple, daily feeding provides all the hormone needed for the baby's growth and development. In most cases, the child will never be able to produce sufficient thyroid hormone. In this sense, hypothyroidism is permanent and treatment must be continued throughout life.
