Examining gut microbiota changes in patients undergoing metabolic surgery
The Gut Microbiota in Metabolic Surgery: A Multi-Ethnic, Multi-Omic, Longitudinal Study
This study is testing how metabolic surgery affects gut bacteria and heart health in patients, especially focusing on the African American community, over the next 10 years.

What this trial studies
This observational study investigates the impact of metabolic surgery on gut microbiota and its relationship with cardiometabolic health outcomes. By enrolling up to 300 patients scheduled for metabolic surgery at Vanderbilt University Medical Center, the study aims to track changes in gut microbiota from pre-surgery to post-surgery over a period of up to 10 years. The research will utilize multi-omics approaches to analyze stool, blood, and tissue samples, focusing particularly on the underrepresented African American population with high rates of cardiometabolic diseases. The goal is to fill existing research gaps and better understand how gut microbiota influences surgical outcomes.
Who should consider this trial
Good fit: Ideal candidates are individuals approved for metabolic surgery who have a history of type 2 diabetes, hypertension, or dyslipidemia.
Not a fit: Patients with prior gastric operations, certain cardiovascular conditions, or current gastrointestinal diseases may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and management of obesity-related metabolic diseases, enhancing surgical outcomes for patients.
How similar studies have performed: While there is limited research on the specific relationship between gut microbiota and metabolic surgery outcomes, similar studies have shown promising results in understanding microbiota's role in metabolic health.
