Autoimmune thyroid disease is usually less serious if the patient’s condition is well controlled, and is more serious if the patient’s condition is not well controlled. Autoimmune thyroid disease is a thyroid disease caused by damage to the thyroid gland caused by the autoimmune system in protecting the thyroid gland. Thyroid diseases such as Hashimoto’s thyroiditis and toxic diffuse goiter are more common and are mainly manifested as hyperthyroidism or hypothyroidism, and usually have a better prognosis if they are detected and treated early. If autoimmune thyroid disease causes hypothyroidism and is not treated in time, it may also lead to lifelong hypothyroidism and may even cause serious cardiovascular disease. Therefore, once you have autoimmune thyroid disease, it is recommended that you go to the endocrinology department of a regular hospital as soon as possible, and take timely and symptomatic treatment measures.
