There are multiple types and designs for bariatric surgery. As everyone knows, the presence of multiple options means there is NO perfect option.
Types of bariatric procedures:
1- Restrictive (restricting the amount of food the stomach can hold)
2- Malabsorptive (causing malabsorption of nutrients)
3- Restrictive with malabsorptive component (a combination of both gastric restriction and malabsorption).
Bariatric procedures also often cause hormonal changes.
The most common bariatric surgery procedures are:
1- Roux-En-Y Gastric Bypass (RYGBP)
2- Sleeve gastrectomy
3- Adjustable gastric banding
4- Gastric balloon (ORBERA®)
Weight loss surgeries performed by experienced surgeons today are carried out using minimally invasive techniques (Laparoscopic or Robotic surgery).
