    Synthroid treats thyroid nodules by reducing the levels of another hormone called thyroid stimulating hormone (TSH). TSH is made in the pituitary gland, and it functions to make the thyroid gland produce more hormones. TSH stimulates the growth of thyroid cells, which can increase thyroid nodules. Lowering TSH levels will have the opposite effect, reducing the size of thyroid nodules.
