Which clinical sign typically does not align with hyperthyroid conditions?

• A. Weight loss
• B. Tachycardia
• C. Fatigue
• D. Exophthalmos

Answer: (C)

In hyperthyroid conditions, the clinical signs are primarily characterized by an increase in metabolic activity due to excess thyroid hormones. Weight loss occurs as the metabolism accelerates, leading to an increase in energy expenditure despite potentially increased appetite. Tachycardia is also commonly observed, as these hormones can increase heart rate and contractility, creating a faster heartbeat. Exophthalmos, or protruding eyes, is a specific manifestation often associated with Graves' disease, a common cause of hyperthyroidism, where inflammation and swelling behind the eye occur due to autoimmune processes. Fatigue, while it can occur in hyperthyroid patients, is not a hallmark sign of the condition. In fact, many patients with hyperthyroidism report increased energy levels or feel hyperactive, in contrast to the lethargy often observed in hypothyroid conditions. Therefore, fatigue does not typically align with the classic symptoms of hyperthyroidism, making it the correct choice in this context.
