An overactive thyroid, also known as hyperthyroidism, is a serious condition that can cause a variety of health problems if not treated properly. Hyperthyroidism is caused by an excess of thyroid hormones in the body, resulting in symptoms such as rapid heartbeat, weight loss, anxiety, fatigue, and difficulty sleeping. Left untreated, an overactive thyroid can lead to serious health complications such as heart failure, stroke, and even death.

Causes of an Overactive Thyroid
The most common cause of an overactive thyroid is an autoimmune disorder called Graves’ disease. Other causes include an overactive thyroid nodule, an enlarged thyroid, and certain medications. In some cases, the cause of an overactive thyroid is unknown.
Treatment of an Overactive Thyroid
The primary treatment for an overactive thyroid is medication, such as antithyroid drugs, beta-blockers, and thyroid hormone replacement therapy.
