What is a common symptom of hyperthyroidism?

A common symptom of hyperthyroidism is weight loss. This condition occurs when the thyroid gland produces an excess of thyroid hormones, which significantly increases metabolic rate. As a result, individuals with hyperthyroidism often experience unintended weight loss despite having an appetite that may be increased or unchanged. The heightened metabolism leads to the body burning calories more rapidly, thus contributing to weight loss.

Other symptoms associated with hyperthyroidism also include increased heart rate, anxiety, and tremors, but weight loss is particularly notable as it contrasts sharply with hypothyroidism, where individuals typically gain weight. Understanding this distinction is crucial for diagnosing and managing thyroid-related conditions effectively.
