Hyperthyroidism (Overactive Thyroid)

Hyperthyroidism, or an overactive thyroid, occurs when the thyroid gland produces excessive amounts of thyroid hormones, speeding up the body's metabolism. Symptoms like rapid heartbeat, nervousness, and sweating can be mistaken for anxiety. It's important to differentiate hyperthyroidism from anxiety by recognizing physical symptoms such as tremors, unexplained weight loss, heat intolerance, and goiter (enlarged thyroid gland). Blood tests measuring thyroid hormone levels are crucial for diagnosis.
