Preoperative malnutrition, identified by standard nutritional indices (SGA, NRI, MI, MNA), significantly increases the risk of postoperative morbidity (specifically severe infectious and non-infectious complications) and mortality in patients undergoing major elective surgery.
Before major surgery, assess your nutritional status. If you are malnourished, your risk of complications like infections or wound healing issues increases significantly (by 2-3x). Work with your care team to optimize nutrition preoperatively, as this is a critical factor in surgical outcomes, not just the surgery itself.
Morbidity rates, especially severe infectious and noninfectious complications, were significantly higher in malnourished patients in all nutritional indices.
Why this rating
Large prospective cohort (n=460) with blinded outcome assessment, though single-center.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
