She finds it hard to fall asleep and awakens 1 hour before the alarm goes off each morning. She has been drinking 2 to 3 cups of coffee daily for the past 7 years and has smoked one pack of cigarettes daily for the past 3 years. Her temperature is 37.4C 99.4F, pulse is 110min, respirations are 18min, and blood pressure is 15070 mm Hg. Examination shows moist palms. Neurologic examination shows a fine resting tremor of the hands. Deep tendon reflexes are 3 with a shortened relaxation phase.

The key findings are:- Palpitations on minimal exertion or at rest- Anxiety, irritability, insomnia - suggest hyperthyroidism - Weight loss despite increased appetite - suggests hyperthyroidism- Tremors - suggest hyperthyroidism- Hyperreflexia with shortened relaxation phase - suggests hyperthyroidismThe history also reveals she has recently started taking an herbal weight loss pill. This raises suspicion for exogenous hyperthyroidism from the supplement. Coffee consumption and smoking are unlikely to cause her constellation of symptoms. Generalized anxiety disorder would not explain the palpitations, weight loss, tremors or hyperreflexia. Pheochromocytoma could cause palpitations and anxiety but not the other findings. The most likely diagnosis is exogenous hyperthyroidism from the herbal weight loss supplement.D: Exogenous hyperthyroidism
