In Graves' disease, thyrotoxic crisis can be indicated by which symptom?

• A. Pallor
• B. Fever
• C. Bradycardia
• D. Weight gain

Answer: (B)

In a thyrotoxic crisis, the body undergoes a severe hypermetabolic surge from excess thyroid hormone, leading to a marked increase in heat production and a high fever. This fever is a distinctive feature of thyroid storm and reflects the overwhelmed metabolic state, often accompanied by rapid heart rate, sweating, tremor, and agitation. Among the given options, fever best represents this crisis-related change. Pallor, bradycardia, and weight gain are not characteristic of thyroid storm; in fact, thyrotoxicosis more commonly presents with tachycardia and weight loss.
