Overview
This is a randomized controlled trial to compare intra-gastric injection of Botulinum Toxin A (Botox; Allergan Inc. Irvine, Ca, USA) against non-surgical management for obesity (i.e. exercise/diet). Our hypothesis is that intra-gastric injection of Botox into the fundus and body of the stomach will result in greater weight loss than just exercise and diet alone.
