4. Overactive Thyroid: The Hyperactive Catalyst of AFIB
Next on our list is the thyroid – a small, butterfly-shaped gland nestled in our necks, with an influence that extends far beyond its size. The hormones it secretes govern numerous body functions, including metabolism, growth, and even heart rate. An overactive thyroid, or hyperthyroidism, churns out excess hormones, driving the heart into overdrive, and often leading to AFIB.
The intricate links between the thyroid gland and the heart are an important piece of the AFIB puzzle. When the thyroid goes into hyperdrive, the heart follows suit, often resulting in a rapid, irregular heartbeat – a characteristic feature of AFIB.
Effectively managing hyperthyroidism can, therefore, be a crucial step towards preventing or controlling AFIB. This management might include medications, radioiodine therapy, or, in some cases, surgery. (4)
