Gastric Bypass vs Gastric Sleeve

When diet and exercise alone don’t lead to the desired results, bariatric surgery may emerge as a light of hope. Among the options, Gastric Bypass and Gastric Sleeve stand out as popular choices, each with its own path to potential wellness.

So, let’s delve into the world of Gastric Bypass vs Gastric Sleeve surgery and find the path that best aligns with your goals and lifestyle.

Understanding Bariatric Surgery

First, let’s talk about Bariatric Surgery in general to know what it is and how it can help you lose weight.

Bariatric surgery, or weight-loss surgery, is a life-altering intervention designed for those who struggle with obesity and its associated health risks. This surgery involves making changes to the digestive system to facilitate weight loss, which is particularly beneficial when the traditional methods like diet and exercise have not yielded results.

 A Brief History of Bariatric Procedures

1. Modern bariatric surgery evolved in the mid-20th century.

2. Initial procedures focused on malabsorption, while later techniques aimed to restrict food intake.

3. Current Bariatric surgery methods combine both approaches.

4. Laparoscopic techniques now reduce recovery time and enhance outcomes.

As we said previously, out of several different types of bariatric surgery, gastric bypass and gastric sleeve stand out as very popular choices for losing weight. So, let’s talk about gastric Bypass vs gastric sleeve surgery.

Gastric Bypass: The Gold Standard

♦ What is Gastric Bypass?

Gastric Bypass, specifically the Roux-en-Y Gastric Bypass, is a significant weight-loss surgery that involves creating a small pouch from the upper part of the stomach and linking it directly to the small intestine. This surgery effectively reduces the stomach’s size and alters the path food takes through the digestive system.

♦ How does it work?

During the procedure, Dr Balaji constructs a small stomach pouch and attaches it to a lower part of the small intestine, by passing a large portion of the stomach, duodenum and a variable part of the small intestine.  

Now you have an idea about this surgery and how it is done. Let’s move to the next type of surgery in our blog.

Gastric Sleeve: The Rising Star

Are you ready to find out more about Gastric Sleeve? Let’s start!

♦ What is a Gastric Sleeve?

Gastric sleeve, or Sleeve Gastrectomy, is a surgery for weight loss. It involves the removal of approximately 80% of the stomach, leaving a tube-shaped stomach similar to the size and shape of a banana.

♦ How does it work?

The surgery is typically performed laparoscopically and works by not only reducing the stomach’s capacity, thereby limiting food intake, but also by prompting hormonal changes that reduce hunger by improving satiety. These changes can also help alleviate conditions associated with being overweight.

With a clearer understanding of the individual surgical paths, we now stand at the crossroads of choice. It’s time to illuminate the difference between Gastric sleeve and Gastric bypass.
