Hypothyroidism and thyroid nodules are two different diseases. Hypothyroidism is hypothyroidism, which is an endocrine disorder, most commonly associated with Hashimoto’s disease, and does not necessarily have thyroid nodules, which need to be treated with oral eugenol. A thyroid nodule is a generic term for a swelling in the thyroid gland that does not necessarily cause hypothyroidism. There are benign nodules and malignant nodules, and you need to go to the hospital for an ultrasound examination to determine the nature of the thyroid nodule and whether surgery is needed. If the thyroid nodule is benign and relatively small, you may not need treatment for the time being and regular follow-up is sufficient. If the thyroid nodule is diagnosed as malignant or if the nodule is large and has symptoms of pressure, surgery may be required.
