Normal stomach emptying test values after weight-loss surgery
Part of Digestive system clinical trials.
This study measures how quickly food leaves the stomach in people who had weight-loss surgery (gastric bypass or sleeve gastrectomy) at least 2 years ago. The goal is to create normal reference values for this test, which may help doctors better understand digestive issues after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You had a gastric bypass (RYGB) or sleeve gastrectomy (SG) as your first weight-loss surgery.
- It has been at least 2 years since your surgery, and you had no major problems from it.
- You have lost a normal amount of weight (between 25% and 35% of your total body weight).
- You are willing to follow the study schedule and give permission for your doctor to be told if something unexpected is found on a scan.

This study looks at how digestion works after weight-loss surgery. Volunteers may be people with obesity or those who had gastric bypass or sleeve gastrectomy at least a year ago. The goal is to learn more about gut function after surgery.
This study uses ultrasound to see how quickly your stomach empties after a meal. It aims to learn more about normal stomach function in healthy adults.
This study looks at how well the stomach empties in intensive care patients who are on a breathing machine and receiving liquid food through a tube. It compares patients who are also on ECMO (a machine that helps the heart and lungs) with those who are not, to see if ECMO affects stomach emptying.
This study measures how quickly a baby’s stomach empties after formula feeding. It may help doctors better understand normal digestion timing in newborns and infants.
This study tests how a special diet after weight-loss surgery affects gut bacteria, eating habits, and sense of taste and smell. Researchers want to see if this diet can improve long-term results.
This study looks at how GLP-1 medications affect the time it takes for your stomach to empty before anesthesia. It may help doctors decide if you need to take special precautions before your surgery.
