Abstract:
Bariatric surgery achieves lasting weight loss and improves the comorbidities associated with morbid obesity. After surgery, patients can develop complications, mainly mild nutritional alterations. However, in some patients, complications can be serious and lifethreatening. We present the case of a 50-year-old woman who developed severe protein-calorie malnutrition after bariatric surgery, which required surgical reversion. The factors leading to malnutrition in this patient and the treatment options are discussed.
