What condition may result from an overactive thyroid gland?

An overactive thyroid gland, also known as hyperthyroidism, leads to a condition called thyrotoxicosis. This occurs when there is an excessive amount of thyroid hormones circulating in the body, which can significantly increase the body's metabolism and lead to a wide range of symptoms. Common manifestations of thyrotoxicosis include rapid heart rate, weight loss, increased appetite, nervousness, and heat intolerance.

The condition itself arises from various causes, such as Graves' disease, toxic nodular goiter, or thyroiditis. In each case, the excessive production of thyroid hormones disrupts normal metabolic function and can lead to serious complications if not properly managed. Understanding thyrotoxicosis is crucial for recognizing the effects of hyperthyroidism and guiding appropriate treatment interventions to restore hormonal balance.
