I added this new article. Feel free to post comments or questions about it! PERMANENT VERSUS TEMPORARY THYROIDITIS: See it on the homepage of Thyroid Health --- What is the difference between Hashimoto's thyroiditis and temporary/transient thyroiditis? The differences -- Hashimoto's is an autoimmune disease causing destruction of the thyroid (lifelong hypothyroidism), while temporary thyroiditis resolves and does not require lifelong treatment.
