NCBS: Post-operative Energy Intake (2017)
What is the effect of bariatric surgery on energy intake in adults?
Eight studies [including gastric bypass, gastric band, sleeve gastrectomy and biliopancreatic diversion patients (with the majority of patients having undergone gastric bypass)] reported a clinically meaningful and statistically significant reduction in self-reported energy intake after bariatric surgery. Six studies reported a reduction ranging from 45% to 72% during the first six months post-surgery, five studies reported a reduction ranging from 19% to 50% at one year post-surgery, four studies reported a reduction ranging from 30% to 62% at two years post-surgery and one study reported a reduction ranging from 28% to 38% at four and five years post-surgery, when compared with pre-surgical energy intake. These wide ranges may be due to the variation in methods used to measure energy intake. Ongoing research is needed regarding the effect of available bariatric surgical options on energy intake.
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.
