Gastric bypass surgery with or without nerve cutting for diabetes

This trial is testing whether combining gastric bypass surgery with a procedure that cuts the vagus nerve (a major nerve controlling digestion) helps people with type 2 diabetes achieve remission better than gastric bypass surgery alone. The vagus nerve controls how your body digests food and regulates blood sugar. Researchers believe that cutting this nerve, in addition to the standard gastric bypass procedure, may improve how your body handles glucose and reduce insulin resistance.

Gastric bypass surgery alone helps many people with type 2 diabetes, but doctors want to know if they can improve those results even further. Research suggests that the vagus nerve may be contributing to insulin resistance and poor blood sugar control, so adding a procedure to interrupt this nerve's signaling might provide additional benefit beyond weight loss alone.
