Some hyperthyroidism necks will become larger, and some will not grow, which is directly related to the specific condition. If the condition of hyperthyroidism is not serious, it is only accompanied by a slight increase in thyroid hormone level, and there is no other thyroid discomfort, generally there will be no obvious enlargement. If hyperthyroidism is serious, the thyroid follicles will proliferate and become hypertrophic under the effect of hormone level, and the neck will become larger. Some patients with hyperthyroidism are accompanied by thyroid enlargement, or have nodules and tumors. When the size is large, the neck will also be significantly enlarged. Some hyperthyroidism neck enlargement is not directly related to hyperthyroidism, for example, there is a tumor in the neck, fat accumulation caused by obesity, etc., which needs to be considered comprehensively.
