What are signs of thyrotoxicosis?

Explanation:
Excess thyroid hormone speeds up metabolism and boosts sympathetic nervous system activity. That combination causes tachycardia, tremor, heat intolerance, weight loss, and anxiety—classic signs of thyrotoxicosis. The other patterns fit opposite thyroid function: bradycardia with fatigue, cold intolerance, and weight gain point to hypothyroidism; seizures and coma can occur only in a severe thyroid storm, not the typical presentation; and anorexia with constipation aligns more with hypothyroid-type symptoms.
