Malnutrition After Malabsorptive Metabolic Bariatric Surgery: When Should the Surgery Be Reversed?

Severe malnutrition following bariatric surgery is rare (1.4%) but serious. Reversal procedures are effective treatment options; however, they should be performed by an expert team in tertiary centers. While certain clinical features were commonly observed in our patient series, these findings cannot be generalized due to study limitations. Nonetheless, they can help inform future research. The question of when to perform reversal procedures remains unresolved, underscoring the need for larger, multicenter studies to better define indications and optimal timing.
