The Claim
In patients undergoing knee arthroplasty, postoperative oral carbohydrate intake is associated with a 15% reduction in time to first flatus and an 8% reduction in time to first bowel movement compared to plain water.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After knee replacement surgery, drinking a carbohydrate solution instead of plain water is associated with faster return of bowel function, measured as earlier passage of gas and first bowel movement.
See the scientific wording
In patients undergoing knee arthroplasty, postoperative oral carbohydrate intake is associated with a 15% reduction in time to first flatus and a 8% reduction in time to first bowel movement compared to plain water, indicating accelerated gastrointestinal recovery.
After surgery, the body releases stress hormones that block insulin action and slow the gut. Eating a sugary drink right after surgery tells the body to release insulin, which pulls sugar into muscles and stops the liver from making more sugar. This lowers stress signals and reduces inflammation in the gut, allowing the intestines to start moving again faster, so gas and bowel movements return sooner.
What the research says
1 studyAfter knee surgery, patients who drank a sugary drink right away passed gas and had a bowel movement faster than those who only drank water—exactly as the claim says.
