Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery).
The Laparoscopic Sleeve Gastrectomy is performed by removing approximately 80 percent of the stomach.
The Mini Gastric Bypass procedure is brief, simple, safe and increasingly has provided reliable weight loss.
