Hashimoto’s disease, or Hashimoto’s thyroiditis, is usually reviewed once every six months to a year if there are no specific abnormalities. If there are significant changes in thyroid function and thyroid ultrasound, regular reviews are performed under the direction of your doctor. For those with normal thyroid function in Hashimoto’s thyroiditis, thyroid function is usually checked every six months to a year, and thyroid antibodies and ultrasound are feasible when necessary. Because Hashimoto’s thyroiditis may progress to hypothyroidism, it is necessary to review thyroid function periodically to determine whether hypothyroidism is present and to adjust the treatment plan. If symptoms of hypothyroidism such as chills and fever have already appeared, it is necessary to check the thyroid function in advance in the hospital. Observe the condition of the thyroid gland and lymph nodes in the neck, and perform ultrasonography promptly if there is any abnormality. For Hashimoto’s disease with suspected malignant nodes, the interval of ultrasound review needs to be shortened.
