Hashimoto’s thyroiditis: This disease, also known as chronic lymphocytic goiter, is an autoimmune disease with high TPOAb and TGAb values, which is the basis for the development of Hashimoto’s thyroid disease and is associated with a genetic susceptibility gene, often with others in the family suffering from this disease. The main clinical manifestations are enlargement of the thyroid gland (thick neck) and low thyroid function (thyroid function), while some people may have normal or hyperthyroidism. The pathology is characterized by the destruction of thyroid tissue by lymphocyte infiltration, so a significant proportion of patients will require lifelong replacement therapy with thyroxine (e.g., eugenol) as most of the thyroid tissue is gradually destroyed over time. Only a small percentage of patients go into remission, which may be temporary, and then relapse when stimulated by some external factors. This is why our doctors generally do not say that the disease is cured, and even if remission is discontinued, the thyroid function needs to be reviewed regularly. I think thyroid disease is relatively well-treated disease, do not carry too much burden of thought for this, because many parents think that their children may be lifelong medication is not acceptable, in fact, I have a lot of people around me also suffer from this disease, as normal life and work, just take some medicine every day. So as long as you keep your nail function (T3, T4, TSH, FT3, FT4) normal under the guidance of your doctor, (TPOAb etc. can be abnormal), it will not affect the growth and development. This disease is closely related to a higher intake of iodine, so you should not eat too much iodine-containing things in general.
