What can be a consequence of untreated hyperthyroidism?

Untreated hyperthyroidism can lead to various serious complications, one of which includes heart complications. The excess thyroid hormones produced in hyperthyroidism can significantly increase the heart rate (tachycardia) and can lead to arrhythmias, such as atrial fibrillation. These conditions put extra strain on the heart and can elevate the risk of heart failure or other cardiovascular issues over time.

The impact of hyperthyroidism on the cardiovascular system is particularly critical because it can exacerbate pre-existing conditions and contribute to long-term damage if not managed appropriately. Therefore, ongoing monitoring and treatment of hyperthyroidism are essential to prevent these potentially life-threatening complications.
