Summary

This trial will study how different modifications to the gastric bypass surgery affect molecular and metabolic changes in the body, in an effort to create targeted therapies for patients with morbid obesity.

Who is the study for?
This trial is for adults over 18 with severe obesity (BMI of 40-60 kg/m2) who are planning to undergo laparoscopic Roux-en-Y gastric bypass surgery and meet their insurance's criteria for weight loss surgery coverage. Participants must be willing to have blood tests, provide stool samples before and after the operation, and attend required follow-ups.
What is being tested?
The study is testing how different lengths of intestine bypass (50 cm, 100 cm, or 150 cm) during gastric bypass surgery affect weight loss outcomes. It will also compare these surgeries with a sleeve gastrectomy group and a non-surgical therapy group while examining gut microbiome changes and hormone levels.
What are the potential side effects?
Potential side effects may include typical risks associated with weight loss surgeries such as nutritional deficiencies due to malabsorption, surgical complications like infections or bleeding, gastrointestinal symptoms like nausea or vomiting, and changes in bowel habits.
