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.


Will you lose weight fast with Bariatric surgery?

There is no doubt about it. All the techniques lead to fast weight loss. Some are invasive and carry risks of severe weight loss and malnutrition but most of the techniques are very beneficial in reducing weight. Now a day the most recommended, non-invasive and reversible technique is an intra gastric balloon placement which leads to fast weight loss and when the desired weight is achieved these balloons can be removed. Whatever the technique is adopted weight loss is obvious. But each surgical technique is associated with some side effects, especially the mal-absorptive procedures. In this technique, malabsorption of some essential components of meal may take place including essential amino acids, essential fatty acids and micro-nutrients. These side effects can be decreased by following the instructions of your surgeon and dietician regarding pattern and composition of diet and exercise.


It is very clear that with Bariatric surgery you will lose weight fast but it should be indicated as a treatment of morbid obesity, obesity which is affecting the quality of life, obesity complicating diabetes and cardiovascular diseases. On the other hand, Bariatric surgery helps fast weight loss without heavy exercises and prolonged periods of starvation.
