The Evolution of Bariatric Surgery: A look into the past, present, and future of weight-loss surgeries

Bariatric surgery has truly evolved from its humble beginnings, with minimally invasive surgery now in the lead for many patients. It’s been a journey of discovery, and we owe much thanks to many insightful pioneers in this field. 

Bariatric surgery is a medical procedure that aids in weight loss by altering the digestive system. It’s proven to be an effective strategy against obesity and metabolic disorders, significantly boosting life quality for numerous individuals. 

This article dives deeper into the history, current state, and future projections of bariatric surgery while breaking down two particular procedures: the gastric balloon and the gastric sleeve. We’ll explain how these procedures work, weigh their benefits against their drawbacks, and speak on their significance in shaping bariatric surgery as we know it.

The Past – Early Bariatric Surgery Procedures

The tale of bariatric surgery takes us way back to the 10th century when Spain saw the debut of this type of operation. But if we’re talking about bariatric medicine as a proper field, it’s not that old – only about 70 years old. 

Bariatric surgery has seen remarkable medical and technological upgrades in its history, as there are effective and safe ways to carry out different types of bariatric surgery. Way back when these surgeries were complex with a high chance of complications, laparoscopic surgery came along and replaced those complicated procedures with something safer and less invasive.

Here are a couple of the early bariatric surgery procedures:

  • The Jejunoileal Bypass

Surgeons clued into nutrient absorption, playing a key role in weight gain, and developed the jejunoileal bypass surgery. This involved rerouting sections of the small intestine, which missed a large amount where absorption took place. It did help bring about some impressive weight loss thanks to its malabsorptive method. Still, it also unleashed complications. Patients frequently endured chronic diarrhea, disturbance in electrolyte balance, severe undernourishment, and bacterial overgrowth attributable to considerable bypassing that sometimes even led to liver failure—due to toxin buildup caused by these bacteria.

  • Vertical Banded Gastroplasty (VBG)

VBG tried to create some order in restrictive bariatric surgery by stapling the stomach into a little pouch and placing a band around it. The aim was simple – to shrink the stomach space and slow down the passageway for food digestion so patients felt full from less food. It looked like they were onto something, offering better results than previous operations. But this method caused band erosion and staple lines, making people squeamish – reducing its popularity over time.

The Present – Modern Bariatric Surgery Procedures

Even with the tricky complications of early weight loss surgeries, they still steered in today’s modern procedures. The ’90s brought about laparoscopic surgery, which totally flipped the bariatric surgery process, making it way less intrusive and a lot safer.

Today’s weight loss procedures boast phenomenal advancements, taking them from unattainable to accessible and from generally risky to pretty safe for individuals looking to tackle obesity-related issues head-on. Unlike older methods, our present-day techniques are all about minimal invasion with significantly lower complication possibilities. 

Laparoscopic surgery was a game-changer when it entered the scene in the 1990s. It changed how surgeons operated, making things less invasive – leading to better safety and faster patient recovery times. At this point in time, weight loss surgery stands tall as a proven effective method for managing one’s weight and treating health problems caused by obesity.

Let’s dive into two widely adopted modern-weight procedures: Gastric Balloon and Gastric Sleeve:

  • Gastric Balloon Procedure

The gastric balloon is a non-invasive method for tackling weight issues. It revolves around a saline-filled silicone balloon placed right inside the patient’s stomach. The main job of this balloon is to grab a good amount of space within the stomach, tricking it into thinking it’s full sooner than usual and cutting down on how much food you eat. 

This approach is ideal for individuals with a Body Mass Index (BMI) somewhere between 30 to 40. If traditional weight-loss strategies – dieting and workouts – didn’t do anything for you, the gastric balloon might be your answer. What’s great about this approach is its temporary effect – usually, after six months, out goes the balloon! During this timeframe, you can expect to lose approximately 10% to 15% of your total body fat!

  • Gastric Sleeve Procedure

The gastric sleeve, or the sleeve gastrectomy, is a step up from the gastric balloon in terms of invasiveness. What this surgery does is remove 80% of your stomach. What’s left behind mimics the shape of a banana and can’t take in food like before.

But it’s not just about downsizing the stomach – hormone changes induced by this operation aid us a lot when shedding pounds. This method is mainly proposed for people whose BMI has crossed 40 or those hovering between 35 and 39.9 but grappling with serious health consequences because of their weight—conditions like type 2 diabetes or hypertension. As for results, you’re looking at losing around half to two-thirds of that extra weight after you’ve gone under the surgery, with most seen within two years post-op.

The Future – Advancements in Bariatric Surgery

Bariatric surgery is changing and changing fast. As obesity climbs higher on the Global Problems List, finding better, safer, and less invasive techniques takes center stage. The goal? Better results for the patients. Less time with bandages. Fewer complications.

  • Robot-Assisted Surgery

Robotic systems like da Vinci Surgical System are transforming bariatric surgery from something quite human into something more machine-like—and that’s a good thing! Robot-assisted surgeries give surgeons better vision, precision, dexterity, and control than their traditional counterparts—all beneficial improvements when performing surgery. Robotic procedures translate into precise surgical cuts, which means lower blood loss and a post-op experience that hurts less—a win-win for everyone involved! The result after surgery: shorter hospital stays and fast recovery times.

  • Single-Incision Surgery

Making surgery less intrusive is the goal, and single-incision surgery lives up to that. Instead of several, a single incision at the belly button is all it takes. The perks are clear – minimum scars, lesser after-surgery discomfort, and a more pleasing surgical result.

  • Endoscopic Sleeve Gastroplasty (ESG)

This method is a big deviation from customary surgery. With ESG, an endoscope is used for internally stitching the stomach to create a restrictive sleeve. No cuts mean reduced risks of surgical mishaps like infections or hernias from ESG procedures. Plus, recovery times get cut down as there’s no external healing required.


Bariatric surgery has certainly changed the game since its humble beginnings. It is a real lifesaver for people struggling with obesity and metabolic issues. 


In the early stages, these surgeries were rough around the edges and often coupled with heavy complications—yet they set the stage for state-of-the-art techniques used today. Modern procedures such as gastric balloons and gastric sleeves are far less intrusive and come with a shorter list of potential issues compared to their predecessors.
