Introduction
This page focuses specifically on what actually happens during ESG (Endoscopic Sleeve Gastroplasty) — the procedure mechanics and recovery process. For the broader picture — who's a good candidate, how ESG compares to surgical options, and detailed outcomes data including real Indian results — see the Obesity Clinic page, where that content lives in full.
How the procedure is performed, step by step
- Anesthesia: the procedure is performed under sedation, so you're comfortable and unaware throughout
- Access: an endoscope fitted with a specialized suturing device is passed through the mouth, down the esophagus, into the stomach — no external incision is made anywhere
- Suturing: working from inside the stomach, the endoscopist places a series of full-thickness sutures in a systematic pattern, folding and reducing the stomach's internal capacity, typically reshaping it into a narrower, sleeve-like configuration
- Duration: the procedure itself typically takes around 60 to 90 minutes
- Completion: once the desired reduction in stomach capacity is achieved, the endoscope is withdrawn — there's nothing left inside the body beyond the sutures themselves
Recovery, day by day
| Timeframe | What to expect |
|---|---|
| Day of procedure | Recovery from sedation; typically an overnight stay for observation |
| Days 1–7 | Clear liquids only, to allow the stomach to begin healing |
| Weeks 2–3 | Progression to full liquids, then pureed foods, as guided by your care team |
| Weeks 4+ | Gradual transition to soft, then regular solid foods, with continued nutritional guidance |
This staged progression isn't arbitrary — it directly supports proper healing of the sutured tissue, and skipping ahead too quickly can affect both comfort and results.
What you may feel during recovery
- Mild to moderate abdominal discomfort or cramping in the first few days, generally manageable with standard pain relief
- Nausea, particularly in the first day or two
- A noticeably reduced capacity for food and liquid from very early on — this is the intended effect, not a complication
Nutritional counselling: a built-in part of the process
Nutritional guidance isn't a separate add-on to ESG — it's structured into the recovery process itself, since the diet progression directly affects both comfort during healing and long-term results. Ongoing follow-up with the care team continues well beyond the initial recovery period, supporting the lifestyle changes that work alongside the procedure's physical effect (see the Obesity Clinic page for more on the long-term picture).
ESG care at KAGE
ESG is a stitching procedure, not a stapling one, so nothing is cut away and nothing is left implanted — but the weight loss it achieves depends heavily on the diet and follow-up programme that runs with it. Eligibility criteria and published outcomes are set out in full on the Obesity Clinic page. Our gastroenterologists assess BMI, prior weight-loss attempts, and reflux status before offering it. To discuss whether ESG fits your situation, book a consultation.
Frequently asked questions
No — the entire procedure is performed through an endoscope passed through the mouth, with no external incisions of any kind.
This is a gradual, staged process over several weeks — starting with clear liquids, progressing to full liquids, then pureed and soft foods, before returning to regular solids, all guided by your care team.
Yes — a significantly reduced capacity for food and liquid is the intended effect of the procedure, not a sign of a problem.
Most patients stay overnight for observation and go home the following day.
Following the staged diet progression exactly as guided, rather than advancing faster than recommended, is the most important thing for both comfort and results during recovery.
That's covered in full on the Obesity Clinic page, including real Indian outcomes data, candidacy criteria, and how ESG compares to other options.
It's a built-in, structured part of the recovery process, not a separate add-on — it directly supports both healing and long-term results.
Follow-up is part of standard care, though the specific schedule depends on your individual recovery and results, discussed with your care team.
This is monitored as part of ongoing follow-up; your care team can discuss what this could mean for your specific situation if it's a concern.
