Stomach reduction without surgery usually means endoscopic sleeve gastroplasty (ESG). A suturing device attached to an endoscope is passed through the mouth and used to stitch the stomach into a narrow tube from the inside, with no cuts on the skin and nothing removed. The gastric balloon is the other non-surgical option.
ESG typically produces loss of 15 to 20 in 100 of total body weight at one year: more than a balloon, less than a surgical sleeve. Evidence beyond 5 years is still limited and stitches can loosen, so it should be seen as a newer procedure with medium-term data.
What Non-Surgical Stomach Reduction (Endoscopic Sleeve) involves
Under general anaesthetic with a breathing tube, the endoscopist first checks the stomach for ulcers or other problems. An overtube protects the throat. The suturing endoscope then places a series of full-thickness running stitches along the front wall, greater curve and back wall of the stomach, working from the lower body up towards the top. When each stitch is pulled tight, the stomach wall is gathered in like a drawstring. Six to eight such sutures reduce the volume by about 70 in 100 and shorten the stomach. The uppermost part (fundus) is usually left open as a small pouch. Nothing is cut or removed, so the stomach's blood supply and nerves remain intact.
Who is a good candidate for Non-Surgical Stomach Reduction (Endoscopic Sleeve)?
It sits between diet or medication and bariatric surgery, for people with obesity who want to avoid an operation or do not qualify for one.
- Adults with a BMI of about 30 to 40
- People for whom surgery is too risky or who refuse it
- Those who commit to diet and activity changes with a dietitian
- Some people with weight regain after earlier treatment, following assessment
It is usually not the right choice if:
- BMI above 45 to 50, where surgery is far more effective
- Active stomach ulcers, a large hiatus hernia or previous stomach surgery
- Bleeding disorders or anticoagulants that cannot be stopped
- Pregnancy
- Untreated eating disorder
- People wanting a result equal to a surgical sleeve
Technique options
- Endoscopic sleeve gastroplasty (ESG): The main suturing technique; the best studied endoscopic reduction.
- Gastric balloon: A temporary volume-occupying device for 4 to 12 months.
- Endoscopic revision (TORe): Suturing to tighten a stretched outlet after gastric bypass.
- GLP-1 based weight loss medicines: Injectable drugs that may be used instead of, or alongside, endoscopic treatment; they need long-term prescription at home.
What happens during your treatment
The procedure takes 60 to 90 minutes under general anaesthetic. Most centres keep you for one night. Cramping pain in the upper abdomen, nausea and sometimes vomiting are common for the first 2 to 3 days and are treated with medicines through a drip and then tablets.
Preparing for your trip
One procedure during a stay of 4 to 6 days: tests and consultation on day 1, ESG on day 2 with a night in hospital, and 2 to 3 days nearby until nausea settles and you are drinking well. Dietitian follow-up continues by video.
- Tell the doctor about medication, allergies, pregnancy or breastfeeding, and any history of cold sores, keloid scars or autoimmune disease
- Avoid alcohol, aspirin and anti-inflammatory painkillers for a few days beforehand if your own doctor agrees, to reduce bruising
- Arrive without make-up on the treatment area and avoid sunbeds and strong sun for two weeks before
Recovery and results
Liquids for 2 weeks, then purees for 2 weeks, then soft and normal food by about 6 weeks, mainly to protect the stitches while the stomach scars into its new shape. Most people return to desk work in 3 to 5 days. Avoid heavy lifting and straining for 4 weeks. An acid-suppressing tablet is taken for some months. Weight loss continues for 6 to 12 months.
- Back to everyday activity: 3 to 5 days
- When results show: Over 6 to 12 months
- How long they last: Medium-term data to about 5 years; can be re-tightened
Safety, risks and revision policy
Serious complications occur in about 1 to 2 in 100 procedures.
- Pain, nausea and vomiting for several days, occasionally needing re-admission
- Bleeding from the stomach wall
- Fluid collection or abscess beside the stomach
- Leak or perforation, which is rare
- Stitches loosening over time, with return of stomach capacity
- Less weight loss than hoped for, or weight regain
- Later bariatric surgery remains possible but may be more difficult

Frequently Asked Questions
How does it differ from a surgical gastric sleeve?
Nothing is removed and there are no incisions. Recovery is faster and the risks are lower, but average weight loss is about half to two thirds of the surgical result.
Can it be reversed or repeated?
Stitches can be cut early on if needed, and the procedure can be repeated or converted to surgery later.
Is it a well-established treatment?
A randomised trial and several large series support it for up to about 5 years. Long-term durability is less certain than for surgery.
Would injections be a better choice?
Newer weight loss medicines can match or exceed ESG results while taken, but weight tends to return when stopped. Discuss both options.
