Hashimoto’s thyroiditis is a type of autoimmune thyroiditis, which is an immune-mediated inflammatory response in the thyroid gland. Hashimoto’s thyroiditis is a type of autoimmune thyroiditis, an immune-mediated inflammatory reaction of the thyroid gland. It is more common in women, especially young and middle-aged women, but in recent years the incidence has developed at a younger age and is increasing year by year. As a result of the destruction of thyroid cells by antibodies, the thyroid gland becomes enlarged and hard, followed by hyperthyroidism, or hypothyroidism and a series of other symptoms. In the early stages, there are usually no symptoms, but as the disease worsens, there may be multiple stages of hyperthyroidism, or hyperthyroidism with hypothyroidism, or hypothyroidism. The use of glucocorticoids is not recommended for the treatment of Hashimoto’s thyroiditis. If patients present with clinical manifestations of hyperthyroidism, they are usually treated with antithyroid drugs; if they present with clinical signs of hypothyroidism, they are usually treated with levothyroxine instead. If patients present with unrelieved pain or significant pressure symptoms, surgical removal of the thyroid gland may be considered depending on their quality and the severity of their condition. When patients with Hashimoto’s thyroiditis undergo ultrasound imaging, they will find a diffusely enlarged thyroid gland with abundant blood flow and marked hypoechogenicity of the entire gland with a fine thread network-like echogenicity. Therefore, Hashimoto’s thyroiditis is an autoimmune inflammatory response and patients need to go to the hospital for diagnosis and treatment in a timely manner.
