One of our Patient Support Team members will organise your initial consultation with one of our expert bariatric Surgeons.
The Procedure
The Endoscopic Sleeve Gastroplasty (ESG), is a newer weight loss procedure, that avoids surgery. Sutures are used to form a small banana shaped chamber in the stomach, reducing the volume of the stomach by about 65-70%, without the need for surgery.
How does the ESG work?
Like the gastric sleeve, the ESG reduces your stomach size, limiting the amount you can eat, so you’ll feel full more quickly!
ESG is a relatively new procedure, so long-term weight loss outcome data is not available. Patients can expect to lose 15-20% of their body weight, with improvement in any weight related illnesses too.
Most procedures are performed as a day-case or with a single night in hospital. Most patients will be back to normal activities and work within a few days, or a week of surgery.
Am I suitable?
The ESG has been designed to support patients with a Body Mass Index (BMI) of 30 and above, who want to avoid conventional weight loss surgery. You can calculate this via our online tool.
To support your success as with any weight loss surgery, patients need to be prepared to work hard with the ESG and follow the advice given by your clinical team.
However, not everyone is suitable for the ESG procedure and you would need an initial assessment with a Bariatric Consultant Specialist to assess your suitability and ensure the ESG is right for you.

At Streamline we offer a bespoke service to all of our patients – this is because all our patients are unique in their own way and they are likely to have different needs and requirements. When you book a free consultation with one of our bariatric surgeons we will arrange a pre-consultation telephone call for you. This is where our surgeon will call you prior to your consultation and go through the details of the operation you are considering.


Your initial consultation is an opportunity to meet with your surgeon, to discuss your weight loss history and the best weight loss treatment options for you.

Following your initial consultation with your surgeon, you will also meet with one of our dietitians to discuss your pre and post-surgery care and diet plan, to maximise your weight loss success.

A few days before your procedure you will have to attend a pre-assessment appointment at your treating hospital.

On the day of your surgery, you will be welcomed at your treating hospital by the nursing staff, who will take you to your private room and prep you for your surgery.

You will be taken down to theatres to have your procedure and will usually require an overnight stay at the hospital.

Around 48 hours after your procedure one of our bariatric nursing team will be in touch to see how you are and to answer any questions you may have.

Shortly after your call from our nurse you will have an appointment with your dietitian to go over through the post-operative diet plan.

All of our patients benefit from a 2-year aftercare programme, where you’ll have regular contact with your surgeon and our support team, who will work with you to help you achieve your weight loss goals.

Your consultation is free and you‘re under no obligation to go ahead with surgery. Complete your details below and we‘ll be in touch with more information. Don‘t worry, we won‘t share your details with anyone else, we just need them so we can get in touch and help in the best way possible.
