Does Having My Thyroid Removed Affect My Heart?
Find the truth about questions that pique your curiosity in our series, “The Short Answer.” Preventive cardiologist Haitham Ahmed, MD, MPH, answers this one about cardiovascular disease.
A: The thyroid is important because thyroid levels control your energy level and heart rate, your bowel function and your concentration. When you have your thyroid removed, it’s really important to replace the thyroid hormone to the appropriate amount so you can still function normally. Your endocrinologist, primary care doctor or your cardiologist should be checking your thyroid hormones level, which is called the TSH, to make sure it’s where it needs to be. With too much thyroid hormone, your heart may be racing. If you have too little, your heart pumping function may be reduced. In extreme situations, you may even have very low energy and have something called myxedema coma. These are just a few examples of the effects of thyroid hormone on the heart.
