What are the symptoms of hyperthyroidism?

Hyperthyroidism is a condition characterized by an overproduction of thyroid hormones, which can significantly influence various bodily functions. One of the hallmark symptoms of hyperthyroidism is weight loss, which occurs because the increased levels of thyroid hormones accelerate the body's metabolism. This heightened metabolic state often leads to the body burning calories more quickly than normal, resulting in unintended weight loss.

In addition to weight loss, another prominent symptom is an increased heart rate, also known as tachycardia. The elevated levels of thyroid hormones stimulate the heart, causing it to beat faster. This can also manifest as palpitations or an irregular heartbeat in some individuals. Other symptoms associated with hyperthyroidism may include anxiety, irritability, heat intolerance, increased sweating, and changes in menstrual patterns.

Recognizing these symptoms is crucial for diagnosing hyperthyroidism and differentiating it from conditions that present with different metabolic and endocrine symptoms. The combination of weight loss and increased heart rate provides significant insight into the underlying hyperthyroid state.
