An eating disorder may present as a concern about food, weight, or appearance, but the immediate threat can be cardiovascular, metabolic, or psychiatric. Starvation, purging, rapid weight loss, and the metabolic shifts that follow refeeding can impair perfusion, cardiac conduction, and organ function. The patient's appearance or BMI alone cannot determine safety. The nurse's first clinical question is therefore physiological: Is this patient stable enough for outpatient treatment and routine nutritional rehabilitation today? A stable patient should receive the least intensive effective treatment, while bradycardia, hypotension, hypothermia, severe electrolyte abnormality, rapid weight loss, or altered mental status changes the priority to urgent medical stabilization.
