Which patient profile is at highest risk for myxedema coma?

• A. Young healthy adult
• B. Child with fever
• C. Athlete after exercise
• D. Elderly woman with recent infection

Answer: (D)

Myxedema coma is a life-threatening decompensation of hypothyroidism triggered by another illness or physiological stress. It most commonly occurs in older adults, especially elderly women, who have known or undiagnosed hypothyroidism. An infection is a classic precipitating factor that can push a frail thyrotoxic state into crisis, leading to mental status changes, hypothermia, bradycardia, hypotension, and metabolic disturbances such as hyponatremia. Because this profile combines advanced age, female predominance, and a recent infection as a precipitating stressor, it carries the highest risk for myxedema coma. The other profiles lack the combination of underlying hypothyroid status and a significant triggering illness, so they are far less likely to experience this specific emergency. This condition is an emergency requiring rapid recognition and treatment with thyroid hormone replacement and supportive measures.
