Summary
This study tests a new, personalized version of a weight-loss surgery called SADI-S. Surgeons will measure each patient's small intestine and adjust the bypass length to maximize weight loss while lowering the risk of vitamin deficiencies. The study includes 40 adults with obesity, and participants will be followed for at least a year to track weight, health improvements, and side effects.
