Which symptom is NOT typically associated with hyperthyroidism?

• A. Tremors of extremities
• B. Tachycardia
• C. Fatigue
• D. Exophthalmos

Answer: (C)

Hyperthyroidism is characterized by an overproduction of thyroid hormones, resulting in a hypermetabolic state. Common symptoms associated with this condition include tremors of the extremities, tachycardia (increased heart rate), and exophthalmos (protrusion of the eyes). Tremors occur due to heightened neural activity and increased sympathetic nervous system stimulation. Tachycardia is a direct result of the increased metabolic demand that hyperthyroidism creates; the body works harder to maintain homeostasis. Exophthalmos is particularly seen in Graves' disease, an autoimmune form of hyperthyroidism, where inflammation and swelling of the tissues behind the eyes lead to this eye protrusion. In contrast, fatigue, while it may occur in hyperthyroid patients due to the body's constant state of heightened activity, is not a classic or defining symptom of hyperthyroidism. Instead, many patients typically experience increased energy levels and reduced fatigue, which aligns with the overall hyperdynamic state caused by excess thyroid hormone. Thus, the symptom that stands out as not typically associated with hyperthyroidism in this context is fatigue.
