Myxedema coma

Myxedema coma is state of decompensated hypothyroidism. The patient may have lab values identical to a "normal" hypothyroid state, but a stressful event (infections, MI, CVA, drugs, etc.) precipitates the myxedema coma state. Primary symptoms of myxedema coma are altered mental status and hypothermia. Hypoglycemia, hypotension, hyponatremia, bradycardia, and hypoventilation may also occur. Myxedema, although included in the eponym, is not necessarily seen in myxedema coma.
