Endoscopic Sleeve Gastroplasty: The No-Cut Option Between Injections and Surgery
ESG stitches the stomach into a narrow tube from the inside, with no incisions and nothing removed. It sits between medication and surgery on effectiveness, invasiveness and cost.

Clinical Editorial
The short answer: endoscopic sleeve gastroplasty, usually shortened to ESG, uses a suturing device passed through the mouth to fold and stitch the stomach into a narrow sleeve from the inside. Nothing is cut and nothing is removed. Weight loss sits between a balloon and a surgical sleeve, recovery is faster than surgery, and the anatomy is left largely intact, which keeps future options open.
How it differs from a surgical sleeve
| Feature | Balloon | ESG | Surgical sleeve |
|---|---|---|---|
| Incisions | None | None | Keyhole incisions |
| Stomach removed | No | No | Yes, most of it |
| Reversibility | Fully, at removal | Sutures can loosen or be revised | Not reversible |
| Typical weight loss | Lowest of the three | Intermediate | Highest |
| Duration of effect | Six months only | Years, with variation | Permanent anatomical change |
| Hospital stay | Day procedure | Day case or one night | Two to three days |
What the procedure involves
It is done under general anaesthesia, through the mouth, typically taking around an hour to ninety minutes. A series of full-thickness sutures pull the stomach wall inward along its length, reducing volume and slowing emptying. Most patients go home the same day or after one night, and return to desk work within a few days. A staged liquid to soft diet follows for several weeks, similar to surgery but usually shorter.
Why 'no cut' matters clinically
Because nothing is stapled, cut or rerouted, the specific complications of surgical sleeve and bypass, such as staple line leaks and internal hernias, do not apply in the same way. That is a genuine advantage. It is not the same as risk-free: bleeding, perforation and collections are described, and it is still a procedure under general anaesthesia.
What it costs and where to get it
ESG is available at a limited number of Indian centres with the required suturing platform and trained endoscopists, mostly in metros. Costs are typically in the range of a surgical sleeve or somewhat below, roughly ₹2.5 lakh to ₹4 lakh at private hospitals depending on city and centre. Insurance coverage is inconsistent, since policies were written around surgical bariatric criteria; ask for pre-authorisation in writing rather than assuming.
Who it suits
- People in the BMI range below surgical criteria who want more than medication alone.
- People who want a procedure but are unwilling to accept permanent removal of the stomach.
- People with a specific reason to avoid abdominal surgery.
- People who want to preserve the option of surgery later, since ESG does not usually preclude it.
Where it does not fit
ESG is generally not the right answer for someone with a very high BMI who needs the largest possible weight loss, for whom surgery remains the stronger option. It is also not a fix for significant reflux or a large hiatus hernia, and it does not carry the diabetes remission evidence that gastric bypass does. And, like every option on this page, it does not work without the eating and activity changes alongside.

Key takeaways
- ESG stitches the stomach into a narrow tube from the inside, with no incisions and nothing removed.
- Results sit between the gastric balloon and surgical sleeve.
- Recovery is faster than surgery, often a day case or single overnight stay.
- Available at a limited number of Indian centres, typically ₹2.5 lakh to ₹4 lakh.
- It does not carry the diabetes remission evidence of gastric bypass.
Frequently asked questions
Is ESG the same as gastric sleeve surgery?
No. Surgical sleeve removes most of the stomach through keyhole incisions. ESG stitches the stomach smaller from the inside with nothing removed and no incisions.
How long do the ESG sutures last?
Sutures are intended to be durable and results are reported over years, but some loosening can occur and outcomes vary between individuals. Long-term data is shorter than for surgical procedures.
Can I have surgery later if ESG does not work?
In most cases yes, because the anatomy is preserved. Confirm this with the treating team for your specific situation.
Is ESG available in India?
Yes, at a limited number of centres, mainly in larger cities, since it requires a specific endoscopic suturing platform and trained operators.
Does insurance cover ESG in India?
Coverage is inconsistent because policy wordings were built around surgical bariatric criteria. Seek written pre-authorisation rather than assuming it will be reimbursed.
