Hyperthyroidism is caused when the thyroid is overactive—producing too much of the hormone thyroxine, causing normal body functions, such as metabolism to speed up. Recent research suggests that hyperthyroidism may have a tremendous affect on the most important organs in your body, your heart. In recent studies, researchers have found a correlation between hyperthyroidism and atrial fibrillation. They put together that atrial fibrillation is a common outcome of hyperthyroidism. Atrial fibrillation, commonly called “A fib” is characterized by uncoordinated contractions of the atria in the heart and can result in a fast and irregular heart rhythm. Hypothyroidism and the affect on the heart is still to be researched further.

Previous research has shown that hyperthyroidism is more prevalent in the female population than the male population, and age is not a risk factor. More recently, a team of researchers carried out a study in Denmark where they collected thyroid function blood tests from 586,460 patients with hyperthyroidism that consulted their practitioners. They followed these patients for a span of 10 years. After five years, the data suggested that, out of 586,460 participants, over half of the women in the study had developed A fib.

Researchers suggested that there should be a higher watch on this topic to make this situation more publicized so people can become more aware of hyperthyroidism and the underlying threat of developing A fib. People can take better control over major health conditions by regular physician check-ups, eating and maintaining a healthy diet, exercise, and most importantly avoid smoking and alcohol. These simple tasks will keep you, your heart and body healthy longer, for a better you!
