It is a common cause of hyperthyroidism in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).Decreased iodine leads to decreased thyroid hormone.)

Risk factors for toxic multinodular goiter include individuals over 60 years of age and being female.
