How can I treat hyperthyroidism naturally, without prescriptions?

Very unlikely. 3 common causes of spontaneous hyperthyroidism. Overactive nodular goiters produce more thyroid hormone over time, and do not resolve unless medically or surgically treated. Graves' is an autoimmune disease that can go into remission, but usually after taking anti-thyroid rx for while. Inflammatory thyroiditis is a self-resolving condition that may lead to hypothyroid. Answer depends on which type.
