Bariatric Surgery: Bariatric surgery promotes accelerated weight loss by altering the digestive system to limit the amount of food that can be eaten and digested. There are a number of different surgical procedures that have been shown to result in rapid weight loss, yet again, psychological and behavioral factors have been shown to reliably predict post-procedural outcomes. Most physicians and insurance companies require a bariatric presurgical psychological evaluation prior to moving forward with surgical interventions to treat obesity.
