TYPES OF BARIATRIC SURGERY
Bariatric surgery is considered to be the most effective treatment for obesity in terms of maintenance of long-term weight loss and improvement in obesity-related comorbid conditions.
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 cause desired hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery).
