Bariatric Surgery Types: How different are they from each other?

Someone who has not found success with diet and exercises – as far as weight loss is concerned- will inevitably turn to a surgery to get rid of the excess weight. There are four bariatric surgery types aimed at helping you with your weight loss goals by limiting the amount of food eaten by you. And, how do they do that? By reducing the size of your stomach.

Types of Bariatric Surgery

So, if all these weight loss surgeries – i.e. Gastric Bypass, Sleeve Gastrectomy, Adjustable Gas Band and Bilopancreatic Diversion- work by reducing your stomach then why or how are they different from each other? The bariatric surgery types are different because they employ different ways to “reduce” the size of your stomach.

With the help of Gastric Bypass Surgery, the surgeon divides your stomach into two sections. The upper part is now as small as a pouch. The surgeon staples it with the mid-section of your small intestine. The restrictive-malabsorptive surgery not only reduces the size of your stomach but also ensures that a large part of the food bypasses the small intestine.

With Sleeve Gastrectomy, the surgeon just goes on to sever 75% of your stomach from your body thereby leaving you with a sleeve.

If you’re opting for a lap band surgery, then the surgeon will tie a band around your stomach making sure that the upper part of the same is only capable of holding only a cup of food.

A Bilopancreatic Diversion also aims at reducing the size of your stomach and make way for the food to bypass the small intestine. It is to be noted that owing to the complications involved, the surgery is only recommended to people who are super-obese – i.e. having BMI of 50+.


Usually bariatric surgery can be availed only by people having Body Mass Index of 40+. However, if you have BMI of 35+ but are suffering from serious diseases like Type II diabetes, the surgeon might just recommend a surgery.

However, one should not forget that “failure of diets and exercises” is a precondition. Established programs will require you to furnish proof of your failed attempts before actually recommending the surgery. There is no room for arbitrary decisions here. You might as well hit the gym for two or three days only to end up with the feeling that it’s not your cup of tea. So you think you will rather opt for a surgery. Sorry! That’s not happening!


What more? Let us tell you that even surgeries are no “rosy” road to weight loss. Depending on the type of surgery you have opted for (only after thorough discussions with the surgeon) you can expect to lose around 50 to 80% of excess fat. However, long term benefits can only be enjoyed when you are ready to bring about complementary lifestyle changes including diet and exercises.

Gastric Bypass surgery, for instance, might as well result in fast weight loss (up to 80% of your excess body weight). However, let us tell you that there are serious chances of regaining weight if you don’t follow it up with exercises.
