Excessive thyroid iodine

Iodine is a relatively important element in the human body. There are many elements in the human body, and different elements have different effects on our body, including iodine. If there is a problem with iodine, it is particularly easy to cause thyroid disease. However, sometimes there will be too much iodine. So what is the reason for excessive thyroid iodine?

The thyroid gland is iodine deficient

Based on medical history analysis and clinical manifestations, goiter can also be divided into: 1. Compensatory goiter: Physiological compensatory goiter that occurs during adolescence or late adolescence, more common in women, and also includes goiter during pregnancy. This is because the synthesis of thyroid hormones in the body cannot meet the ever-increasing physiological needs, so the thyroid gland becomes compensatory and enlarged. This type of thyroid gland is usually mildly or moderately enlarged, soft in texture, or of medium hardness, with normal thyroid function and usually no signs of local compression.

2. Multinodular goiter

Multinodular goiter may be caused by a mild synthesis disorder of thyroid hormone. Because of the decrease in serum T4, the pituitary gland secretes reactively, resulting in a slight increase in TSH, causing goiter. Because goiter is compensatory, thyroid function is normal in most patients.

Most cases are clinically asymptomatic, with only enlarged thyroid gland and nodules found during physical examination. Patients often seek medical attention due to airway obstruction or difficulty swallowing. For those with mild symptoms, they should be carefully asked whether they have airway obstruction. The patient's thyroid gland may also be enlarged behind the sternum, with jugular venous distension and facial congestion when the arms are extended upward and a palpable retrosternal goiter is visible. A small number of older patients with multinodular goiter may also develop hyperthyroidism.

3. Congenital goiter

It is a congenital disorder of thyroid hormone synthesis. In severe cases, it is sporadic cretinism, which is a myxedema syndrome in infancy, characterized by growth and development disorders, mental retardation, diffuse myxedema throughout the body, and obvious symptoms and signs of hypothyroidism.
