Synthroid, a thyroid hormone, is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. Without this hormone, the body cannot function properly, resulting in poor growth, slow speech, lack of energy, weight gain, hair loss, dry thick skin, and increased sensitivity to cold. When taken correctly, Synthroid reverses these symptoms. Synthroid also is used to treat congenital hypothyroidism (cretinism) and goiter (enlarged thyroid gland).
