GLP-1 Agonists After Bariatric Surgery

This study is looking at how continuing or stopping GLP-1 receptor agonists (a type of medication that helps regulate blood sugar and appetite) after weight-loss surgery affects people with morbid obesity, metabolic syndrome, diabetes, high blood pressure, or sleep apnea. You could join if you are over 18, having weight-loss surgery at MU Health Care, and currently taking a GLP-1 receptor agonist. The researchers want to see how these medications impact weight loss, certain substances in your blood (circulating bile acids and metabolites), and the types of bacteria in your gut (gut microbiome diversity) six months after surgery. The current recruitment status is unclear.

Study design
This interventional study plans to enroll 150 participants who will be randomly assigned to either continue or discontinue GLP-1 receptor agonists after bariatric surgery.
What's involved
Recruitment occurs at the preoperative education class. Participants will be randomized to either continue or discontinue GLP-1 receptor agonists.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 6 months to measure weight loss, circulating bile acids and metabolites, and gut microbiome diversity.

  • Effect of GLP1-RA on weight loss6 months

    To investigate the effects of GLP1-RAs on weight loss reflected as change in BMI (kg per meter sq) in patients undergoing metabolic surgery

  • Effect of GLP1-RA on circulating bile acids and metabolites6 months

    Determine the impact of GLP1-RA on circulating bile acids and other metabolites

  • Effector of GLP1-RA on gut microbiome diversity6 months

    To determine the impact of GLP1-RAs after bariatric surgery on changes in the gut microbiome

  • Effect of GLP1-RA on satiety and hunger6 months

    To assess the impact of GLP-1 agonists on satiety and hunger in patients who undergo metabolic surgery. Scale will be a validated scoring system, "Daily Eats Questionnaire," with scores ranging from 0-10, with a 0 indicating no hunger, and 10 indicating extreme hunger

  • Effect of GLP1-RA on Glycemic control6 months

    HGBA1C levels will be measured at 3 and 6 months after surgery to determine if HGBA1C drops more in patients maintained on GLP1-RA
