ABSTRACT

Autoimmune thyroid disease is one of the commonest autoimmune diseases, affecting 2-4% of women and 1% of men.[1] Almost one-third of the world’s population lives in areas of iodine deficiency. In areas where the daily iodine intake is 50 mg, goitre is usually endemic, and when the daily intake falls 25 mg, congenital hypothyroidism is seen.[2] More women than men are affected by the two most common autoimmune thyroid conditions, Hashimoto's thyroiditis and Graves' disease.[3] In iodine-replete communities, the prevalence of spontaneous hypothyroidism is between 1 and 2%, and it is more common in older women and 10 times more common in women than in men.[2] Graves' disease is the most prevalent cause of primary hypothyroidism, while autoimmune thyroiditis (Hashimoto's disease) is the most typical cause of hyperthyroidism. The majority of people with hypothyroidism must take levothyroxine as part of a lifelong treatment regimen. Despite being uncommon, the development of Hashimoto's disease into Graves' disease has recently drawn greater attention.[3] Conversions from hyperthyroidism to hypothyroidism occur often in clinical practise, although conversion from primary hypothyroidism caused by Hashimoto's disease to hyperthyroidism caused by Graves' disease is rare. Due to the conversion's alleged rarity and the limited number of instances we could locate, its real occurrence is uncertain.[3] Antithyroid medication therapy is straightforward after the diagnosis has been suspected and verified. It is essential to make the correct diagnosis in order to treat these people effectively.[4]
