Tachycardia,vascular collapse,rapid cardiac rhythms,congestive heart failure,and severe hyperthermia are consistent with the clinical manifestations of the hypermetabolic state of thyroid storm.Adrenal insufficiency presents with weakness,fatigue,weight loss,anorexia,abdominal pain,and hyperpigmentation.Myxedema coma is an extreme form of hypothyroidism and is characterized by signs of hypometabolism,including bradycardia,hypotension,hypothermia,cold intolerance,and neurological sluggishness.SIADH is characterized by fluid retention,hyponatremia,and hemodilution.Heat intolerance and atrial fibrillation are not typical characteristics of the condition.
