what causes hyperthyroidism

Hyperthyroidism, the condition where your thyroid gland is overactive and produces too much thyroid hormone, can be caused by a few different things. The most common cause is Graves’ disease, which is an autoimmune disorder. In Graves’ disease, your immune system makes antibodies known as thyroid-stimulating immunoglobulins (TSIs) that cause the thyroid to overproduce hormones. It’s common for this to run in families, so if there’s a family history, that might be a contributing factor. It’s also noteworthy that stress and smoking can sometimes exacerbate or trigger symptoms. Another possible cause is a condition called toxic multinodular goiter, where lumps in the thyroid create excess hormone. Thyroiditis, which is inflammation of the thyroid, can also lead to temporary hyperthyroidism. Lastly, excessive iodine intake either through diet or medications can potentially trigger hyperthyroidism since iodine is a key component in thyroid hormone production.

In terms of your symptoms like the racing heart and feeling hot, they’re textbook signs of hyperthyroidism due to the increased metabolism from hormone overproduction. Now, focusing on what to do, it’s important that you work closely with your healthcare provider on a treatment plan. This might involve medications like antithyroid drugs which help reduce hormone production, or you might discuss options like radioactive iodine therapy. Lifestyle changes, such as managing stress and making dietary adjustments, might be advised to help manage symptoms. If your heart symptoms become severe, it’s crucial to seek immediate medical evaluation since untreated hyperthyroidism can have significant health impacts, particularly on your heart. Generally speaking, with appropriate treatment, many people manage hyperthyroidism effectively and lead normal lives. So, be sure to have an open dialogue with your healthcare provider to explore your options and determine what’s best for you.
