What organs are affected by hypothyroidism?

Hypothyroidism can affect the heart and circulatory system in several ways. Lower production of thyroid hormone slows your heart rate. Hypothyroidism also makes the arteries less elastic, and blood pressure rises in order to circulate blood around the body.
