Whether the thyroid gland can be felt or not should be objectively analyzed based on the presence or absence of nodules in the thyroid gland and whether the thyroid gland is accompanied by diffuse hyperplasia and other factors: i. If the patient’s thyroid hormone level is disturbed, causing diffuse enlargement of the thyroid gland volume, the thyroid gland body is obviously protruding from the surface of the body, and the enlarged thyroid gland can be felt in the neck. ii. In this case, the patient can be adjusted by drugs to maintain the stability of thyroid hormone levels in the body, prompting the enlarged thyroid gland gradually return to normal. Second, if the patient’s thyroid gland is accompanied by nodular hyperplasia of the gland, it can also be manifested as an obvious enlargement of the thyroid gland. During the neck examination, the patient is asked to do swallowing, and the enlarged thyroid gland can be touched. If the size of the thyroid nodule is large, affecting the patient’s aesthetic appearance or considering the possibility of malignant tumors, it is clinically recommended that the patient undergo surgical resection to avoid the spread of tumor cells along the blood vessels and lymphatic vessels, which may cause serious complications.
