Thyroid hormone is made by the thyroid gland in the neck. The thyroid gland normally makes the right amount of thyroid hormone because the pituitary gland tells the thyroid gland how much thyroid hormone it needs to make. With a poorly functioning pituitary gland, the thyroid gland does not get the proper signal (TSH) to make thyroid hormone when it is needed and the person does not make enough thyroid hormone (hypothyroid). Thyroid hormone helps in normal growth and helps make energy for the body to function (metabolism). Lack of thyroid can lead to poor growth, slowing of mental and muscle function, weight gain, feeling cold, irregular periods (menstrual cycle), hair loss, hoarse voice, brittle nails, and dry, coarse skin. Lack of thyroid hormone can be shown with blood tests which measure the amount of thyroid hormone in the body. The main thyroid hormone measured is called thyroxine (or T-4). Thyroid hormone levels should be checked when the diagnosis of ONH is made and at least every year after the diagnosis.

If your child lacks thyroid hormone, he or she can easily by treated with thyroid pills taken be mouth every day. Your child will need to have T-4 measured regularly to see if the right amount of medicine is being given. With proper treatment, your child's thyroid problem will be corrected and he or she will not suffer ill effects.
