The condition is caused by an abnormal immune system response that results in the body’s defenses turn against the thyroid gland, but rather than destroy, create substances that stimulate the synthesis of thyroid hormones, just as the pituitary TSH. It is more common in women than in men.

Toxic nodular goiter

When taking little iodine, or for unknown reasons, the thyroid gland increases in size to meet this lack and try to capture all possible iodine. To grow, the cells that form the gland multiply; sometimes the growth is uncontrolled and each cell forms nodules that produce thyroid hormone on its own without regulation.

Toxic adenoma

It usually occurs within a multinodular goiter in which a lump of control further cell division and facilitating mutates to start synthesize thyroid hormones uncontrollably, as if an extra thyroid gland is formed.

Thyroiditis

A viral infection causes inflammation of the thyroid gland, which expels all reserves containing thyroid hormones and causes a sudden increase this blood. It mainly affects women between 30 and 50 years old. Associated with fever and pain in the jaw or ear.

Other causes of hyperthyroidism
