What is Bariatric Surgery?

Bariatric surgery is well known as weight loss surgery. It is indicated in morbid obese people who failed to reduce weight by all measures. Bariatric surgery includes reducing the size of stomach by various surgical methods like, gastric bypass surgery in which meal is diverted to small intestine directly from the stomach and malabsorption techniques in which absorption of food from the small intestine is decreased. All the methods of Bariatric surgery help in weight loss fast.

Principle of Bariatric surgery

Bariatric surgery should be performed on people with severe obesity. Research studies show that these surgeries cause significant weight loss and help in recovery from diabetes and cardiovascular risk factors. The U.S. National Institutes of Health recommends that Bariatric surgery should be done on people who have a body mass index (BMI) 40 or above. Now a day some non-invasive Bariatric surgeries are being done on people with moderate obesity without any associated morbidity.

Each technique has its own principle. For example

  • Intra-gastric balloon placement, sleeve gastrectomy reduces the capacity of the stomach.
  • Gastric bypass surgeries, duodenal cap lead to malabsorption of food, resulting in fast weight loss.
  • Roux-en-Y hepato-jejunostomy leads to the small size of intestine and helps in decreased absorption of meals.
