IMPROVE-T2D Trial Summary
This trial is testing whether or not a vertical sleeve gastrectomy, a type of weight loss surgery, can help improve Type 2 diabetes in youth by looking at changes in things like insulin resistance, glycemic control, beta-cell function, and cardiovascular health.
Who is the study for?
This trial is for obese youth aged 12-21 with Type 2 Diabetes, scheduled for vertical sleeve gastrectomy (VSG), and a BMI ≥35 kg/m2. Participants must have an HbA1c ≤12% and weigh less than 550 lbs. They cannot be on certain medications like diuretics or blood thinners that can't be stopped safely around the time of surgery.Check my eligibility
What is being tested?
The study tests how bariatric surgery (specifically VSG) affects pancreatic function, kidney health, and cardiovascular wellness in young people with Type 2 Diabetes. It includes measuring various body functions before and after surgery to see improvements.See study design
What are the potential side effects?
Potential side effects may include complications from renal biopsy such as bleeding or infection, reactions to contrast agents used in imaging tests, surgical risks associated with VSG including pain, infection, bleeding, and possible adverse reactions to anesthesia.

Group I: Clinical InvestigationExperimental Treatment4 Interventions
Participants will include youth who are scheduled for, and will undergo, vertical sleeve gastrectomy (VSG) surgery at the Bariatric Surgery Clinic at Children's Hospital of Colorado.
To understand how bariatric surgery affects renal function, all participants will undergo assessment of Glomerular Filtration Rate, (Iohexol Inj 300 mg/mL) and Effective Renal Plasma Flow (Aminohippurate Sodium Inj 20%). In addition, participants will undergo imaging assessment that includes renal Blood Oxygen Level Dependent (BOLD) and Arterial Spin Labeling (ASL) MRI.
