Hashimoto’s thyroid refers to Hashimoto’s thyroiditis, an autoimmune thyroiditis. The cause of Hashimoto’s thyroiditis is not well understood and is usually thought to be due to the interaction of immune, genetic, and environmental factors. In the early stages of the disease, Hashimoto’s thyroiditis may have no obvious clinical symptoms, but as the disease progresses, clinical symptoms such as enlarged thyroid gland, fatigue, fear of cold, memory loss, and loss of appetite may appear. There is no specific treatment for Hashimoto’s thyroiditis. If there is only goiter and no hypothyroidism, treatment is usually not needed. Those with obvious goiter or hypothyroidism need to take levothyroxine replacement therapy. Surgery may be considered for those with significant compression symptoms that are not relieved by levothyroxine therapy. Those with thyrotoxicosis are given beta-blockers for symptomatic management. If you are suffering from Hashimoto’s thyroiditis, while actively treating the disease, you should follow up regularly according to the doctor’s instructions to know the progress of the disease, and the main checkups include thyroid function and thyroid ultrasonography.
