FAQ Endoscopic Sleeve Gastroplasty (ESG)

What is Endoscopic Sleeve Gastroplasty (ESG)?

Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive, non-surgical weight loss procedure that uses an endoscope to reduce the stomach size. This helps limit food intake and promotes a feeling of fullness, resulting in weight loss.

Who is a candidate for ESG?

ESG is typically recommended for individuals with a Body Mass Index (BMI) of 30 or higher who have not succeeded with traditional weight loss methods such as diet and exercise.

What are the benefits of ESG?

Benefits of ESG include significant weight loss, reduced risk of obesity-related health issues, minimal scarring, faster recovery times, and a lower risk of complications compared to surgical weight loss procedures.

What are the risks of ESG?

Risks associated with ESG include minor bleeding, infection, stomach perforation, and adverse reactions to anaesthesia. These risks are generally lower than those related to surgical weight loss procedures.

How is ESG performed?

ESG is performed using an endoscope, a flexible tube with a camera and suturing device attached. The endoscope is inserted through the mouth into the stomach, where the suturing device is used to create folds in the stomach, reducing its size.

How long does the procedure take?

The ESG procedure typically takes between 60 to 90 minutes to complete.

How much weight can I expect to lose after the procedure?

Weight loss varies from person to person, but on average, patients can expect to lose 15-20% of their total body weight within the first year after the procedure.

Will I need to follow a special diet after the procedure?

Yes, you must follow a structured, nutrient-dense diet to ensure proper nutrition and support weight loss. Your healthcare team will provide guidance on the necessary dietary changes.

How long is the recovery process?

Most patients can return to work and resume normal activities within a few days to one week after the procedure. Full recovery typically takes about two weeks.

Can ESG be reversed?

ESG is a reversible procedure. If necessary, the sutures can be removed, and the stomach will return to its original size. However, reversal is uncommon, as most patients experience significant weight loss and improved health after the procedure.
