Failure to substitute nutrients after sleeve gastrectomy or Roux-en-Y gastric bypass can result in nutrient deficiency with potentially fatal consequences.
Is it true that failure to substitute nutrients after sleeve gastrectomy or Roux-en-Y gastric bypass can result in nutrient deficiency with potentially fatal consequences?
Yes. Failure to provide adequate nutritional supplementation following sleeve gastrectomy or Roux-en-Y gastric bypass places patients at high risk for severe, potentially fatal micronutrient and macronutrient deficiencies.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved literature consistently supports the claim that bariatric surgeries such as sleeve gastrectomy and Roux-en-Y gastric bypass alter gastrointestinal anatomy and absorptive capacity, making postoperative nutrient supplementation vital to prevent severe neurological complications, refractory malnutrition, and potentially fatal outcomes.
