You are not alone.
There is a safe path forward.
Evidence-based bariatric care in Turkey — coordinated with structure, clinical honesty, and U.S.-based accountability. Whether you are still exploring, on a waitlist, or have been turned away before, every case is evaluated individually and guided without pressure.
Why weight keeps coming back
— and when surgery makes sense.
Understanding this is the starting point of every honest bariatric consultation we do.
A small center in the brain called the hypothalamus controls weight like a thermostat. When you lose weight, it works to restore the previous level. For this set point to accept a new weight, you need to maintain that weight for at least one year — which is why most diets lead to regain.
Sleeve gastrectomy significantly reduces circulating ghrelin levels by removing the gastric fundus — the primary site of ghrelin production.[1] This isn't just portion control — it changes how the body signals hunger at a hormonal level.
No bariatric procedure works without lifestyle change. Surgery creates the conditions — it does not replace the commitment. Patients who don't adapt their habits over time will regain weight, regardless of the procedure.
Standard criteria are BMI >40, or BMI >35 with comorbidities. But every case is evaluated individually. If you fall below these numbers, that doesn't automatically mean surgery isn't appropriate — our team reviews your full history.[5]
Most bariatric consultations begin with a procedure recommendation. Ours begin with a question: is surgery actually the right step for you right now?
If lifestyle changes, a gastric balloon, or a non-surgical approach is more appropriate for your situation, that's what we'll say — even if it means not proceeding with a coordinated program.
Our founder's clinical background means this evaluation is done with the same honesty applied in a medical consultation, not a sales conversation.
Note: Our clinical approach favors sleeve gastrectomy as the initial step before considering bypass procedures. Gastric bypass permanently alters digestive anatomy — reversal is technically possible but rarely performed. If sleeve results are insufficient, bypass may be evaluated as a second step with the surgical team.
Three approaches.
One right one for your case.
Not every patient needs surgery. We evaluate each case and recommend the pathway that fits — not the one that generates a procedure.
The stomach is reduced to approximately 1/5 of its original volume using a laparoscopic stapling technique. This limits food intake and — critically — removes the part of the stomach that produces most of the hunger hormone ghrelin.
Performed through 5 small incisions. Surgery itself takes 45–90 minutes. Total hospital stay is 3 nights. Pre-operative evaluation adds 1–2 days. Plan for 7–8 days in Istanbul total.
Expected excess weight loss: 60–65% in the first 6 months, remaining 35–40% in the following 6 months.[4]
A silicone balloon is placed endoscopically into the stomach, occupying space and reducing the feeling of hunger by preventing the stomach from emptying fully. The procedure takes 25–30 minutes under sedation. No hospital stay required.
We recommend the 12-month balloon for weight loss purposes. The 6-month option may be used as preparation before surgery in some cases.
Important: the stomach volume is unchanged. The balloon only works if the patient eats in response to hunger signals and stops when full. Without behavioral change, results will not hold.
Botulinum toxin is injected endoscopically into the stomach wall, temporarily paralyzing the muscles and slowing gastric emptying. This delays the feeling of hunger and helps patients tolerate lower-calorie diets. Duration: approximately 6 months.
Procedure takes 25–30 minutes. Same-day discharge. Renewal after 6 months may be needed for sustained effect — the brain requires at least one year at a new weight to accept it as its set point.
On gastric bypass: Our clinical approach favors sleeve gastrectomy as the initial step. Gastric bypass produces effective weight loss but permanently alters digestive anatomy — reversal is technically possible but rarely performed and carries significant risk. Known complications include dumping syndrome, and deficiencies in iron, B12, and calcium requiring lifelong supplementation. Malabsorption is both a mechanism and a risk of the procedure. For patients where sleeve results are insufficient, bypass may be evaluated as a second step in consultation with the surgical team — but not as a first intervention.
Your journey, step by step.
From first question to discharge and beyond — a structured process with no gaps and no guesswork.
Ask questions without commitment. Jason can walk you through the pathways, explain what each involves, and help you understand whether coordination makes sense for your situation.
Anonymous · 24/7Submit your case details — current weight, height, medical history, previous attempts. A coordinator reviews your situation and schedules a call to discuss the evaluation.
No forms publicly visibleOur team reviews your history and identifies the most appropriate pathway. If surgery is recommended, the clinical team at our partner hospital is briefed on your case before you arrive.
No default referralsHotel, transfers, and hospital appointments coordinated before you book your flight. You arrive in Istanbul knowing exactly where to go and what to expect on each day.
Hotel · Transfers · ScheduleBlood tests, consultations, and specialist evaluations. Any medications that need adjustment (blood thinners, anti-diabetics) are managed at this stage. Surgery is confirmed once everything is clear.
1–2 days · Full workupLaparoscopic sleeve gastrectomy is the standard approach: 5 small incisions, 45–90 minutes of surgery time, 3 nights in hospital. In selected patients — including those with very high BMI or prior abdominal surgery — the surgical team may recommend an open approach for safety reasons. A drain is placed along the staple line and removed 1–2 days post-surgery.
4 days · 3 nights hospitalA follow-up consultation the day after discharge before you fly home. Wound check, drain removal if still in place, medication instructions, and dietary guidance for the first month.
Before you fly homeBlood tests at 1, 3, 6, and 12 months. Nutritional deficiencies are identified and supplemented. Your coordinator stays in contact throughout — recovery doesn't end when you board the flight home.
Structured · Remote · OngoingWhat goes into your surgery
— and why it matters.
The outcome of bariatric surgery depends on the surgical team, the materials, and the follow-up protocol. Here's what you can expect.
Stapling and sealing materials from Covidien (USA) and Ethicon (Germany) — the two most established names in surgical stapling technology, with extensive clinical track records.
Covidien · EthiconMost cases are performed laparoscopically — 5 incisions of 1–1.5 cm, significantly less pain and faster recovery than open surgery. In selected patients with very high BMI or prior abdominal surgery, the surgical team may recommend an open approach for safety reasons. Approach is determined case by case.
Case-by-case · Safety firstSurgeon, anesthesiologist, internal medicine specialist, and a physiotherapist for respiratory care post-surgery. Complex cases receive additional specialist reviews before proceeding.
Multi-specialist · Pre-clearedSmoking significantly increases anaesthesia complications. We ask patients to reduce or stop smoking before surgery. The fewer cigarettes, the lower the risk — this is not a routine disclaimer, it's a clinical fact.
Pre-op preparation mattersA small drain is placed along the staple line following surgery and monitored for the first week. This allows early detection of any staple line leakage — a standard precaution, not an indicator of complications.
Leak detection · Early monitoringStaple line leakage risk: approximately 1–3% (systematic review average ~2.4%).[3] Gastric stenosis: less than 2% in contemporary series. These are the known complication rates and they are discussed with every patient before any decision is made — not mentioned in fine print.
Honest · Pre-decision disclosureWhat happens after surgery
is as important as the surgery itself.
The staple line takes up to one month to fully heal. Solid food causes stomach contractions that could stress the suture line. Liquid nutrition only during this period — comparable to the transition feeding of an infant after breast milk.
Transition to soft, mashed, or blended foods for 1–2 weeks. The stomach's function is essentially being replicated externally through food preparation at this stage.
Walking from week 3–4. Gym training from mid-to-end of month 2. Exercise sessions: no less than 30 minutes, no more than 45–50 minutes. Professional guidance recommended to ensure conscious weight loss and minimize sagging.
Deficiencies in vitamins, minerals, and protein are common after sleeve surgery and must be monitored and corrected. Routine blood panels at each milestone — deficiencies identified are replaced with targeted supplementation.
Alcohol consumption is not recommended for the first 6 months. The reduced stomach volume alters alcohol absorption — tolerance changes significantly and unpredictably post-surgery.
The body needs time to stabilize at its new weight and restore reproductive function before pregnancy is safe. Our standard recommendation is to wait a minimum of 18 months post-surgery before conceiving.
The Swedish Obese Subjects (SOS) study — a 24-year prospective trial published in the New England Journal of Medicine — found that patients who underwent bariatric surgery lived on average 3 years longer than matched controls receiving standard obesity care.[6]
It can also resolve insulin resistance and improve blood sugar control to the point where diabetes medication may no longer be needed — because calorie restriction reduces the excess glucose load the pancreas can't handle.
None of this is automatic. The lifespan extension and the disease resolution are outcomes of sustained weight loss — and sustained weight loss requires the lifestyle change to be permanent, not temporary.
