In the absence of fatigue, which of the following is a common symptom of hyperthyroidism?

Hyperthyroidism is a condition characterized by excessive production of thyroid hormones, which can significantly increase metabolism and affect various bodily functions. One of the common and distinctive symptoms associated with hyperthyroidism is exophthalmos, which is the protrusion of the eyes. This symptom arises as a result of swelling in the muscles and tissues around the eyes, often linked to Graves' disease, the most common cause of hyperthyroidism.

Exophthalmos can lead to a range of visual discomforts and is a visible indicator of the thyroid's overactivity. Other symptoms of hyperthyroidism may include weight loss, increased heart rate, anxiety, and heat intolerance, but exophthalmos stands out due to its specific association with the disorder.

Understanding the implications of exophthalmos in hyperthyroidism is crucial, as it helps in identifying and managing this endocrine disorder effectively.
