Introduction
Obesity is a chronic, relapsing condition, and for many patients, lifestyle measures alone don't achieve or sustain meaningful weight loss — while surgical bariatric procedures aren't right, available, or wanted by everyone. KAGE's Obesity Clinic exists specifically to fill that space: endoscopic and medical treatment for weight loss, led by gastroenterologists, for patients who need more than diet and exercise but aren't seeking or don't qualify for surgery. This clinic also treats obesity as what it actually is from a digestive health standpoint — a major driver of several conditions already covered elsewhere on this site, including fatty liver disease, GERD, and gallstones.
How obesity affects digestive health
Obesity isn't just a general health concern — it's one of the most consistent drivers of digestive disease specifically. Excess weight is a leading risk factor for fatty liver disease, worsens GERD by increasing abdominal pressure, and raises the risk of gallstones. This is exactly why a gastroenterology-led approach to weight management makes sense: treating obesity here isn't separate from treating the conditions it drives, it's connected to them directly, often by the same care team.
Who this clinic is for
- Adults with a BMI of 27–40 who have obesity-related health conditions (such as diabetes, fatty liver, or hypertension) but don't meet criteria for, or don't want, surgical bariatric treatment
- Patients who haven't achieved lasting weight loss through diet and lifestyle measures alone
- Patients seeking a less invasive, non-surgical option with a shorter recovery than bariatric surgery
- Patients whose weight is directly contributing to another digestive condition already being managed
Endoscopic Sleeve Gastroplasty (ESG): the centerpiece procedure
ESG is performed entirely through the mouth using an endoscope fitted with a suturing device, reducing the stomach's capacity by placing internal sutures — no external incisions, no permanently implanted device, and no rearrangement of the digestive tract. It's grown into a well-studied option specifically for patients whose obesity falls into the gap between lifestyle intervention (often insufficient on its own) and surgical bariatric procedures (not appropriate or wanted for everyone).
| Outcome | What Indian and regional data shows |
|---|---|
| Weight loss | Total body weight loss in the range of 15–17%, with durability documented out to 4–5 years in Indian follow-up data |
| Diabetes improvement | Improvement seen in around 87% of patients in a regional Asian study |
| Fatty liver improvement | Improvement seen in around 86% of patients in the same study |
| Safety | No major complications reported in published Indian case series; typically a single overnight stay |
| Cost relative to surgery | Roughly one quarter the cost of surgical bariatric procedures |
Comparing your options
| Lifestyle management alone | ESG (endoscopic) | Surgical bariatric procedures | |
|---|---|---|---|
| Invasiveness | None | Endoscopic, no incisions | Surgical |
| Typical candidate | Mild excess weight, early intervention | BMI 27–40, not surgical candidates or preference | BMI ≥35–40+, more significant obesity |
| Recovery | None | Short, often next-day | Longer |
Not every patient is a fit for ESG — more significant obesity, or specific medical circumstances, may still be better served by surgical bariatric referral. Part of this clinic's role is helping determine which path actually fits, not defaulting to one option.
What to expect with ESG
- Before: a thorough evaluation including BMI, obesity-related health conditions, and prior weight-loss attempts, plus baseline blood work
- During: performed under sedation, typically taking 60–90 minutes, using an endoscopic suturing device to reduce stomach capacity
- After: most patients stay overnight for observation; a structured diet progression (liquids, then soft foods, then regular food) follows over several weeks
- Ongoing: regular follow-up with the care team, including nutritional counselling, is a core part of achieving and maintaining results — not an optional add-on
Living with the results: long-term success
ESG changes stomach capacity, but long-term weight management still depends on sustained dietary and lifestyle habits — the procedure creates a meaningful head start, not a guarantee independent of ongoing effort. Regular follow-up allows the care team to track not just weight but the related conditions that motivated treatment in the first place — blood sugar, liver health, and blood pressure among them — and adjust the overall plan as needed over time.
How candidacy is assessed here
The clinic assesses candidacy on more than BMI — eating pattern, reflux status, metabolic markers, and what has already been tried. Where endoscopic treatment fits, our gastroenterologists explain how ESG is performed and what weight loss is realistically achievable and sustainable; the full ESG procedure detail is set out on its own page.

Frequently asked questions
Published data from Indian and regional studies shows total body weight loss in the range of 15–17%, with results documented as durable out to 4–5 years of follow-up — individual results vary based on adherence to the post-procedure plan.
ESG is generally considered for adults with a BMI of 27–40 who haven't achieved lasting results with lifestyle measures alone. A consultation is the best way to determine whether it, surgery, or a medical approach fits your specific situation.
ESG is generally around a quarter of the cost of surgical bariatric procedures, reflecting its less invasive nature and shorter recovery — our team can provide specific pricing during consultation.
Coverage for ESG varies by policy and is less consistently covered than some other endoscopic procedures; our team can help verify your specific coverage and discuss costs during consultation.
Both — regional studies have shown meaningful improvement in diabetes and fatty liver disease alongside weight loss, since obesity is a shared driver of all three.
Most patients stay overnight for observation and can return to normal activities within a few days, following a structured diet progression over the following weeks.
The sutures can, in principle, be adjusted or reversed endoscopically, unlike some surgical bariatric procedures, though it's generally intended and used as a durable, long-term treatment.
Yes — sustained dietary and lifestyle changes are what maintain the results long-term; the procedure creates a substantial head start but works alongside ongoing habits, not independently of them.
Our team can guide you toward the more appropriate option, whether that's a structured medical weight management approach or referral for surgical bariatric evaluation.
It's very possible — obesity is a recognized driver of both conditions, and treating it can directly improve them; this connection is exactly why a gastroenterology-led approach to weight management makes sense.
