• Weight loss surgery is becoming an increasing popular way to combat severe obesity. but it is not a one size fits all solution.There are different types of weight loss surgery, each with a different mechanism .
  • Thorough evaluation by a team of dedicated professionals including surgeons, nutritionists, psychologists, physicians and understanding in detail the patients need, desire and expectations are a must before assigning the patient a particular type of surgery.
  • Depending upon their primary mode of action, weight loss surgeries can be broadly classified into three  categories. They are  restrictive, malabsorptive and combination of restrictive and malabsorptive.


Restrictive bariatric procedures primarily reduce the storage capacity of stomach and does not involve any handling or rerouting of the intestines. The smaller stomach capacity will induce the feeling of fullness quicker than normal, prompting the patients to eat less, while still being satisfied. This method is seen in procedures such as adjustable gastric banding, and vertical sleeve gastrectomy (gastric sleeve).


Malabsorptive bariatric procedures reroute, rearrange or remove part of the digestive system to reduce the body’s absorption of calories from food. Malabsorptive produces more weight loss (typically), then restrictive, but also produces higher unwanted complications and side effects. There are no stand-alone malabsorptive procedures currently being performed today, they’ve all graduated to a combination of restrictive and malabsorptive.


Combination bariatric procedures provide individuals the best chance to reduce morbid obesity. Combination procedures use both techniques (restrictive and malabsorptive) to produce high amounts of ‘excess weight loss’ (amount of weight, determined to be in excess). Some bariatric surgeons describe combination and malabsorptive the same. Current combination surgeries still in operation are gastric bypass, mini gastric bypass, loop duodenal jejunal bypass and duodenal switch.
