Acquired hypothyroidism, sometimes called Hashimoto’s thyroiditis, is a disorder that does not allow the thyroid gland to make enough thyroid hormone. The thyroid gland is located in the neck and is shaped like a butterfly.
There are several hormones made by the thyroid gland that are important for growth and development and puberty. These hormones help with energy level and help the heart, liver, kidney and skin. Thyroid stimulating hormone (TSH) may be high, but the other thyroid hormones (T3 and T4) may be normal.
Acquired hypothyroidism is more common in teenage girls, but can be found in boys and girls of any age.
Acquired hypothyroidism is easily treated. Children who have untreated hypothyroidism have trouble growing, starting puberty and may not develop normally. Most children require life-long treatment.
