Thyroid nodules are not usually fattening. The most common type of thyroid nodule is a benign nodule, also known as a nodular goiter, which occurs more often in women and is associated with abnormalities in the metabolism of thyroxine in the body, as well as with the structure of the diet, so it is important to take appropriate iodine-containing foods. In addition, regular ultrasound examinations of the neck are required. For multiple nodules, further thyroid function measurements are required, as some patients are prone to secondary hyperthyroidism, and surgery may be indicated if necessary. For single isolated lesions or nodules, if the margins are irregular and the internal density is uneven, the possibility of malignancy is not excluded, and the nature of the nodule needs to be clarified by fine needle aspiration.
