Read our Obesity research guide →Researchers want to understand why obesity and type 2 diabetes often happen together in the same person—a connection sometimes called 'diabesity.' This study will collect tissue samples during abdominal surgeries (like weight-loss surgery or gallbladder removal) from people with different weight and blood sugar levels to examine how genes may influence this relationship.
More than 80% of people with diabetes are also obese, but doctors still don't fully understand why these two conditions are so closely linked or how genes play a role. This research aims to fill that gap by studying actual tissue and genetic information from people at different stages of these conditions.

If you qualify and agree to join, researchers will collect small tissue samples during your already-scheduled abdominal surgery—no extra surgery is needed. You'll also have a simple blood test to measure your blood sugar levels. The study involves no additional visits or long-term follow-up; your participation is essentially complete after your surgery and the tissue collection.
