Hashimoto generally refers to Hashimoto’s thyroiditis. If part of the thyroid gland is removed, you may have Hashimoto’s thyroiditis. If all of the thyroid gland is removed, Hashimoto’s thyroiditis is usually not present. Hashimoto’s thyroiditis is a chronic autoimmune inflammation of the thyroid gland. When the body suffers from Hashimoto’s thyroiditis, there may be no typical symptoms in the early stages, and as the disease progresses, symptoms such as neck swelling, easy fatigue, fear of cold, and decreased concentration may appear. Hashimoto’s thyroiditis can be triggered when the immune system produces autoantibodies that attack the remaining thyroid gland, since the patient still has part of the thyroid gland after partial thyroidectomy. If all of the thyroid gland is removed due to severe thyroid disease, Hashimoto’s thyroiditis usually does not occur because the body no longer has a thyroid gland as an endocrine organ. It is recommended that patients who have had their thyroid gland removed pay attention to daily care, such as surgical wound care and dietary care. Patients should also see their doctor for regular checkups to monitor their recovery.
