Is gastric sleeve surgery in Turkey right for you?
A sleeve is a weight-loss operation, not a cosmetic one. According to the US National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), surgery may be recommended for people with a BMI of 35 or higher, and may also be considered for people with a BMI of 30 to 35 who have type 2 diabetes that is hard to control with medication and lifestyle changes.
In his video, Dr. Çaynak explains that eligibility follows international standards: your BMI together with weight-related conditions such as type 2 diabetes or high blood pressure. The surgeon makes the final decision after reviewing your own height, weight and health history.
Source: NIDDK, Definition & Facts of Weight-Loss Surgery. Turkish audio · English subtitles.
Often considered when
- BMI is 35 or higher (NIDDK).
- BMI is 30 to 35 and type 2 diabetes is hard to control (NIDDK).
- You are ready for lifelong changes in how you eat, plus vitamin supplements.
Needs a closer look
- Existing acid reflux. NIDDK lists acid reflux and hiatal hernia among the risks of sleeve gastrectomy, so your surgeon weighs this when choosing between a sleeve and a bypass.
- Type 2 diabetes together with obesity. Dr. Çaynak says a bypass is often preferred when metabolic disease is present, and a sleeve when obesity is the main issue.
- An earlier weight-loss operation. Your surgeon reviews your records before saying what is possible.
We don't operate on everyone.
Eligibility depends on your BMI, overall health and readiness for lifestyle change. A coordinator arranges a remote assessment, and the surgeon decides whether you qualify. If a sleeve is not the right operation for you, you are told before you book anything.
Check if you qualifyHow a sleeve gastrectomy is done
Sleeve gastrectomy changes the size and shape of the stomach. Nothing is rerouted, which is the main difference from a gastric bypass.
1
Small incisions. Weight-loss surgery is mostly done laparoscopically, through small cuts rather than one large incision, under general anesthesia (NIDDK).
2
About 80% of the stomach is removed. The surgeon removes about 80 percent of the stomach, leaving a long, banana-shaped pouch closed with staples (NIDDK).
3
Less room, earlier fullness. The smaller stomach holds less food, so you feel full sooner. NIDDK adds that removing part of the stomach may also affect hormones that influence appetite.
4
It cannot be reversed. Because part of the stomach is permanently removed, the operation cannot be undone (NIDDK). Weigh it as a lifelong decision.
Risks to discuss with your surgeon: NIDDK lists acid reflux and hiatal hernia, vitamin and iron deficiency, and a higher chance of surgery-related problems than a gastric band. As with any operation, bleeding, infection and blood clots are possible.

What you eat after a gastric sleeve
In his video, Dr. Çaynak describes the order: liquids first, then pureed food, and solid food last, guided by a dietitian.
Because the stomach holds much less, NIDDK lists vitamin and iron deficiency among the risks of a sleeve. That is why vitamin supplements and regular check-ups are part of life after surgery, not an optional extra.
Your own dietitian sets your exact stages and timing. Turkish audio · English subtitles.
Weight loss: what trials show
No honest source can promise you a number. The figures below are five-year averages from randomized trials, shown with the measure each trial used, because the two common measures give different percentages.
| Trial | Measure | Gastric sleeve | Gastric bypass |
|---|---|---|---|
| SLEEVEPASS (JAMA, 2018) | Excess weight loss at 5 years | 49% | 57% |
| SM-BOSS (JAMA, 2018) | Excess BMI loss at 5 years | 61% | 68% |
| STAMPEDE (NEJM, 2017) | People with type 2 diabetes reaching HbA1c of 6.0% or less at 5 years | 23% | 29% |
- Ask any clinic that quotes a bigger number which measure and which time point it means.
- Results depend on how you eat, how active you are and whether you attend follow-up. A sleeve is a tool, not a cure.

Sleeve or bypass: one assessment decides
Dr. Çaynak's view in the video: it is the wrong question to ask which one is better. Both are safe in the right hands, and the choice depends on your health. Your surgeon recommends one after reviewing your case.

Gastric sleeve cost in Turkey: how your quote is set
The $5,000 package is confirmed in writing after the surgeon has reviewed your height, weight and health history. For context, NIDDK, the US National Institutes of Health institute, says weight-loss surgery can cost between $15,000 and $25,000 or even more in the United States.
| Item | Gastric sleeve in Turkey (Nexwell package) | Weight-loss surgery, United States (self-pay) |
|---|---|---|
| Price | $5,000 all-inclusive (about £3,940 / €4,386), flights not included. How Nexwell prices treatments | $15,000–$25,000 USD or more |
| Source | Nexwell package price, confirmed in writing after the surgeon's review | NIDDK, “Definition & Facts of Weight-Loss Surgery” (page last reviewed Sept. 2020) |
Not an apples-to-apples comparison: the NIDDK range covers weight-loss surgery in general, not only sleeve gastrectomy, and varies by procedure and complications. Prices in US dollars.
- Included in the package: pre-operative tests, laparoscopic surgery, anesthesia, 3 nights in the hospital, hotel accommodation, dietitian consultations, first-month medications, compression stockings, airport transfers, 12-month remote follow-up.
- Not included: flights.

Gastric sleeve in Turkey: common questions
How much is a gastric sleeve in Turkey?
A gastric sleeve in Turkey through Nexwell costs $5,000 (about £3,940 / €4,386) all-inclusive: surgery, hospital nights, hotel and transfers; flights are not included. The $5,000 package is confirmed in writing after the surgeon has reviewed your height, weight and health history. The cost section above shows the NIDDK range for weight-loss surgery in the United States for context.
Where is gastric sleeve surgery done, Istanbul or Antalya?
Op. Dr. Mesut Çaynak operates at ASV Yaşam Hospital in Antalya, a JCI-accredited hospital, and can also operate in Istanbul. Your coordinator confirms the city and hospital when you get your quote. Antalya is usually reached by connecting through Istanbul.
Who performs the gastric sleeve?
Your surgeon is Op. Dr. Mesut Çaynak, a bariatric surgeon. He has been an SRC-accredited Master Surgeon in Metabolic & Bariatric Surgery since 2021 and has performed more than 3,800 obesity surgery procedures, by his own account. Surgery takes place at ASV Yaşam Hospital, Antalya (JCI-accredited) or, in some cases, in Istanbul.
Am I eligible for a gastric sleeve?
NIDDK says surgery may be recommended for people with a BMI of 35 or higher, and may be considered for a BMI of 30 to 35 with type 2 diabetes that is hard to control. Eligibility also depends on your overall health and readiness for lifestyle change. A coordinator arranges a remote assessment, and the surgeon decides whether you qualify.
What does laparoscopic sleeve gastrectomy involve?
Through small incisions and under general anesthesia, the surgeon removes about 80 percent of the stomach, leaving a banana-shaped pouch closed with staples (NIDDK). The intestine is not rerouted.
How much weight will I lose?
It varies. In randomized trials, average excess weight loss at five years was 49% after a sleeve in SLEEVEPASS, and average excess BMI loss was 61% in SM-BOSS. These are averages, not promises, and the two trials use different measures. Results depend on diet, activity and follow-up.
Is a gastric sleeve reversible?
No. Because part of the stomach is permanently removed, the operation cannot be reversed (NIDDK). Dr. Çaynak describes conversion to a gastric bypass as an option in some cases, for example after weight regain or complications; your surgeon reviews your records first.
How long is the hospital stay, and when can I fly home?
Your package includes 3 nights in the hospital. After surgery the surgeon decides when you are cleared to fly, usually around day 5 to 7. Longer itineraries can mean waiting a few extra days. Most US itineraries connect through Istanbul.
Is it safe?
Every surgery carries risks, including bleeding, infection and blood clots. NIDDK also lists acid reflux, hiatal hernia and vitamin and iron deficiency as risks of a sleeve. Outcomes depend on a thorough pre-operative assessment, the surgeon's experience and follow-up care. We cannot promise results. Dr. Çaynak's team reviews your case first and can decline you if surgery isn't appropriate.
What about follow-up after I'm home?
You get 12 months of remote follow-up with a dietitian. Weight-loss surgery requires lifelong dietary changes and vitamin supplements. If you have severe symptoms at home, go to your nearest emergency room.
Gastric sleeve or gastric bypass: which is right for me?
It depends on your health. Dr. Çaynak says a bypass is often preferred when metabolic disease such as type 2 diabetes is present, and a sleeve when obesity is the main issue. In trials, bypass averaged somewhat more weight loss at five years (57% vs 49% excess weight loss in SLEEVEPASS). Your surgeon recommends one after reviewing your case.
How do I get a personal quote?
Send your height, weight and health history. Dr. Çaynak's team reviews your case in an online consultation and a coordinator sends a written, all-inclusive quote. You decide afterwards; there is no obligation.
