Summary

Researchers are testing whether a carbohydrate-rich clear drink given two hours before bariatric surgery helps patients with metabolic syndrome recover normal gastrointestinal function faster. About 208 adults scheduled for gastric bypass or sleeve gastrectomy will be randomly assigned to receive the drink or a calorie-free placebo while following the same fasting rules. The study tracks how quickly patients tolerate food and pass gas or stool, along with blood sugar levels and nausea, to see if the drink makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a preoperative carbohydrate-containing clear drink
What this could lead to
If it helps, a simple carbohydrate drink before surgery could become a routine step that gets bariatric patients eating and moving their bowels sooner.
What could go wrong
This is a supportive-care study, not a cure, and the benefit may be modest or absent. The drink could also raise blood sugar around surgery in people with metabolic syndrome, which researchers are tracking.
