Inside the Science of Scar-Free Weight Loss with ESG

 
Modern medicine is changing the way we lose weight. If you’ve been searching for a method that’s effective, less invasive, and doesn’t leave visible scars behind, Endoscopic Sleeve Gastroplasty (ESG) at
Bumrungrad International Hospital may be the breakthrough you’ve been waiting for.
 
This innovative procedure blends precision technology with minimally invasive care, helping patients lose weight safely—without undergoing traditional surgery.
 

How ESG Works: A New Approach from the Inside

Unlike surgical procedures that require cutting through the skin and removing parts of the stomach, ESG works entirely from within. Using a thin, flexible endoscope inserted through the mouth, the doctor places sutures along the inside of the stomach, reducing its size without any external incisions.
 
The smaller, banana-shaped stomach holds less food, helping patients feel full sooner and stay satisfied longer. The entire procedure takes around 90 minutes under anesthesia and requires only one night in the hospital.
 

Why ESG Leaves No Visible Scars

Most hospitals still perform laparoscopic weight-loss surgery, which involves multiple incisions on the abdomen. These surgeries, while less invasive than open procedures, still result in visible scars and longer healing time.
 
By contrast, ESG avoids all external wounds. The endoscopic technique used at Bumrungrad’s Digestive Disease Center means:

• No cuts on the skin
• No visible scars
• No stitches to remove
• Minimal pain and a lower risk of complications

 

The Technology Behind the Procedure

The science behind ESG is rooted in advanced endoscopic suturing, a technique developed and refined in top medical centers worldwide. At Bumrungrad, the procedure is performed by a team of specialists trained in U.S.-certified endoscopic techniques, using the latest high-resolution scopes and precision tools. The suturing device used for ESG is FDA-approved specifically for this procedure, ensuring both safety and effectiveness.
 
Every patient undergoes a comprehensive evaluation—including blood work, endoscopy, and cardiopulmonary screening—to ensure safety before the procedure begins.
 

Faster Recovery, Fewer Risks

One of the most important benefits of ESG is its quick recovery time. Most patients are up and moving the next day, and back to light activity in 1–3 days.
 
The risk of complications is low, with a rate of less than 2%. Some people may experience temporary symptoms like nausea or bloating, but these are usually mild and short-lived.

Frequently Asked Questions (FAQ)

Q: What is ESG and how is it different from surgery?
A: ESG (Endoscopic Sleeve Gastroplasty) is a non-surgical weight-loss procedure that reduces stomach size using internal sutures placed via an endoscope inserted through the mouth. Unlike traditional or laparoscopic surgery, ESG involves no external incisions or removal of stomach tissue.
 
Q: Does ESG leave any scars?
A: No. ESG is performed entirely through the mouth, meaning there are no visible scars or skin incisions.
 
Q: How long does recovery take after ESG?
A: Most patients stay in the hospital for just one night and return to normal activities within 1 to 3 days.
 
Q: Is ESG painful?
A: Because there are no external wounds, pain is minimal. Some patients may feel mild nausea or bloating for a few days, which is easily managed with medication.
 
Q: Will I lose weight with ESG?
A: Yes. On average, patients can expect to lose up to 20% of their body weight within the first year, especially when combined with dietary changes and ongoing support.
 
Q: Who is a good candidate for ESG?
A: ESG is generally recommended for adults with a BMI of 30 or higher, particularly those who haven’t succeeded with diet and exercise alone and are looking for a non-surgical option. For Asian patients, who are at higher risk of metabolic disease at lower body weights, ESG may be considered starting at a BMI of 27.5, especially when obesity-related comorbidities—such as diabetes, hypertension, or fatty liver—are present.
