Your guide to the ESG procedure

Discover what ESG (Endoscopic Sleeve Gastroplasty) is and how it works.

Getting started with ESG

Your weight loss journey is unique to you and your body, which is why it’s important to ask your doctor if ESG is an option for you. Our education specialists can also help answer your questions.

About the ESG procedure

ESG is an endoscopic, incisionless procedure performed by a doctor who sutures the stomach with a specialized device.
ESG reduces the stomach size by approximately 70% to 80% using six to eight sutures. This limits the amount of food consumed and the number of calories absorbed by the stomach. It also prolongs the time food remains in the stomach, so you feel full longer.^{1, 2}
Over 25,000 ESG procedures have been performed worldwide.³ If you’d like a more detailed overview of the ESG procedure, watch this video. Please note: The video includes realistic medical illustrations.

After the ESG procedure

In a study, people who had an ESG procedure typically went home the same day and returned to their daily routine in two to three days.²

The most common side effects are gastrointestinal symptoms such as nausea, abdominal pain, vomiting, constipation, burping or diarrhea. These symptoms typically resolve within 30 to 60 days.
ESG can be part of achieving weight loss, but it requires a lasting commitment to losing weight. To lose weight and keep it off, it’s important to live a healthy lifestyle, including eating well and staying active.

In a study, people experienced 13.6% average total body weight loss at one year when combined with diet and lifestyle changes.²

ESG is the starter. In the long run, you have to do the hard work, you have to exercise, you still have to eat healthy.

In a study, patients with class 1 (BMI 30 to <35 kg/m²) or class 2 (BMI 35 to <40 kg/m²) obesity who underwent ESG in conjunction with prescribed diet and exercise counseling achieved an average of 13.6% total body weight loss at year one.

Achieving and maintaining long term results

ESG is designed for gradual, long-lasting weight loss when combined with lifestyle changes. In a study, 68% of people who got an ESG procedure maintained 25% excess body weight loss 24 months after the procedure when they continued diet and lifestyle changes.² Consult with your medical team, or a dietician or nutritionist, since your overall goals are unique to you and your weight loss journey.

How much does ESG cost?

The cost of ESG varies depending on provider location and other factors, so the best first step is to talk to an ESG doctor.

What does insurance cover?

ESG is typically not covered by insurance, but it is FSA/HSA-eligible. Talk with an ESG doctor to understand your specific situation, since coverage and financing options may vary.
