  • The majority of patients respond well to levothyroxine, and they usually take this medication for life. Autoimmune thyroiditis is also known as atrophic thyroiditis or Hashimoto disease when goitre is present.

  • These studies suggest that some patients with subclinical hypothyroidism do indeed have clinical manifestations of mild thyroid failure. Extreme lethargy.
