A new weight loss procedure developed at the Mayo Clinic constricts a patient's stomach without surgery and has led to major weight loss in 10 clinical trial patients, NBC News reported. Over the course of two hours a doctor uses a mechanical suturing device fixed to an endoscope to traverse the esophagus and reshape a patient's stomach, a modification that makes the patient feel full sooner. Unlike a gastric bypass, the procedure can be reversed, repeated and adjusted over a person's lifetime.
