Magnetic weight-loss procedure for diabetes or weight regain
This trial tests a new procedure that uses magnets to reroute part of your small intestine. It is for people with type 2 diabetes or who have had a sleeve gastrectomy and gained weight back. The goal is to see if this magnetic treatment can help with weight loss and diabetes control.
Ahmedabad, GujaratAges 25–65 - NCT02904291Recruiting
