In brief: Yes,

Yes, and there are several ways in which this can happen.
If the hyperthyroidism was caused by a thyroiditis (inflamation of the thyroid) there is typically a hyperthyroid phase followed by a hypothyroid phase. In most cases the thyroid levels then return to normal, but in about 5% of cases the gland never recovers and permanent hypothyroidism ensues. In graves' disease, about 1% of patients will go from hyperthyroid to hypothyroid each year as a consequence of the autoimmune attack on the gland. Treatment with radioactive iodine for hyperthyroidism will result in hypothyroidism in about half of the treated patients.
