Could Hypothyroidism Be Affecting Your Heart?
Published: Aug 18, 2024
Hypothyroidism can lead to significant changes in your heart's function and overall cardiovascular health. This article explores how an underactive thyroid might impact your heart.
What Is Hypothyroidism?
Hypothyroidism is when your thyroid gland doesn't produce enough thyroid hormones, which are crucial for your body's metabolism and energy use. This condition can slow down your body's processes, including those of your heart.
Cardiovascular Effects
In hypothyroidism, your heart's ability to pump blood effectively decreases, leading to lower cardiac output. Additionally, your heart rate slows down, and there's an increase in the resistance of your blood vessels, which can put extra strain on your heart.
Symptoms to Watch Out For
Though not always obvious, signs like fatigue during exercise, swelling, and slow heartbeat can indicate cardiovascular issues due to hypothyroidism. If you experience these, consider discussing them with a healthcare professional.
Impact on Blood Pressure
Hypothyroidism can lead to higher diastolic blood pressure due to increased blood vessel resistance. This kind of hypertension is often subtle yet significant in affecting heart health.
