Study Summary

This trial is looking at whether bariatric surgery can help improve nonalcoholic fatty liver disease (NAFLD) by measuring the liver's ability to burn fat and make glucose.

Who is the study for?
Adults aged 18-67 with a BMI of 30.0-55.0 kg/m2, diagnosed with NASH (NAS ≥3) or non-NASH/NAFLD (NAS ≤3), and possibly T2DM or prediabetes are eligible for this trial focused on liver health in relation to obesity. Participants must consent to surgery, live near the clinic for follow-ups, have insurance covering obesity treatments, and be suitable for liver biopsy.Check my eligibility
What is being tested?
The study is testing how Vertical Sleeve Gastrectomy (VSG), a type of bariatric surgery, affects liver function—specifically fat burning and glucose production—in patients with varying severities of fatty liver disease related to obesity.See study design
What are the potential side effects?
Potential side effects from VSG may include surgical risks like infection or bleeding, nutritional deficiencies due to reduced food intake capacity post-surgery, gastrointestinal issues such as nausea or vomiting, and changes in bowel habits.
