Abstract

A 62-year-old female with chronic pancreatitis and severe protein-calorie malnutrition was hospitalized for persistent abdominal pain and significant unintentional weight loss. Following initiation of enteral nutrition, she developed refeeding syndrome complicated by hypotension and reduced cardiac output requiring intensive care admission. Laboratory studies demonstrated profound hypophosphatemia, hypokalemia, hypomagnesemia, and hypocalcemia. Management included vasopressor support, aggressive electrolyte repletion, and cautious reintroduction of nutrition. Hemodynamics improved with correction of metabolic derangements. This case underscores the perioperative implications of refeeding syndrome and emphasizes the importance of early recognition, gradual nutritional advancement, and close monitoring to prevent life-threatening cardiovascular complications in malnourished patients.
