Normal thyroid gland enlargement
The thyroid tissue has a strong ability to concentrate iodine. The human thyroid gland needs 60-80ug of iodine every day to produce physiologically active thyroid hormones. In the body, there is a feedback relationship of mutual dependence and mutual restriction between the thyroid hormones secreted by the thyroid gland and the thyroid stimulating hormone (TSH) secreted by the pituitary gland. When iodine is deficient, thyroid cells cannot synthesize enough thyroid hormones, the concentration of thyroid hormones in the blood decreases, the inhibitory effect of thyroid hormones on pituitary secretion (TSH) is weakened, the secretion of pituitary TSH increases, and the level of TSH in the blood increases, causing thyroid hypertrophy and hyperplasia.
