Clinical Overview

Bariatric surgery and non-surgical weight-management options are not interchangeable treatments. Meva Clinic coordinates the assessment of international patients for Gastric Sleeve (sleeve gastrectomy), Gastric Bypass, Gastric Balloon and Gastric Botox in Istanbul through specialised partner medical facilities.

Gastric Sleeve or Gastric Bypass?
• Gastric Sleeve: A bariatric procedure that reduces the volume of the stomach without rerouting the intestine. It may be considered depending on BMI, clinical profile, anatomy, reflux history and treatment goals.
• Gastric Bypass: A bariatric and metabolic procedure that creates a small gastric pouch and reroutes part of the small intestine. It may be considered when clinically significant gastroesophageal reflux or certain metabolic conditions influence the choice of procedure.
Assessment framework: No procedure is universally superior. The choice between Gastric Sleeve and Gastric Bypass depends on BMI, obesity-related conditions, gastroesophageal reflux, type 2 diabetes and metabolic health, individual anatomy, medical and surgical history, and multidisciplinary assessment.

Non-Surgical Options:
• Gastric Balloon: A temporary, non-surgical option that does not permanently change the anatomy of the stomach. The pathway differs by device type, and eligibility and monitoring are decided individually.
• Gastric Botox: A non-surgical endoscopic procedure that does not change the anatomy of the stomach. Response varies between patients, and the clinical evidence and durability are more limited than for established bariatric procedures.

Gastroesophageal Reflux and Pre-Operative Tests:
A history of gastroesophageal reflux can influence the choice of procedure. Depending on symptoms, medical history and clinical findings, the treating team may recommend an upper GI endoscopy (EGD) or other pre-operative tests before the treatment plan is confirmed.

Coordination Pathway from Home to Istanbul (5 Steps):
1. Sharing initial information: The patient shares relevant medical history, height, weight, current treatments, previous procedures and any available medical documents.
2. Medical review: The information is passed to the medical team that evaluates the case. Depending on the procedure under consideration and the data available, additional tests or documents may be requested.
3. Written plan and cost quotation: After assessment, the written plan sets out the proposed procedure, the medical provider, the facility where treatment will take place, the confirmed services, any exclusions and the cost set for the assessed case.
4. The Istanbul stage: Appointments and confirmed logistics are organised according to the written plan. Hospital stay and private transfers are included in the confirmed package; hotel accommodation is optional, on request (separate cost).
5. Follow-up once you are back home: Discharge or departure from the medical facility, fitness to fly and follow-up after your return are determined by the procedure, clinical progress and the confirmed plan.

Transparency of the Plan and Medical Quotation:
An initial enquiry is not medical approval and does not automatically set the final price. Once the available information has been reviewed, the patient receives a written plan stating the proposed procedure, the medical provider, the included services, any exclusions and the confirmed cost for the assessed case.

Available Procedures

Gastric Sleeve in Turkey (Sleeve Gastrectomy)

Gastric sleeve, also known as sleeve gastrectomy or stomach reduction surgery, is a laparoscopic bariatric procedure in which a significant part of the stomach is removed. Whether it is indicated, and the final plan, are decided by the specialist surgeon after a clinical assessment.

A bariatric and metabolic surgery option for eligible patients with severe obesity, including some patients with type 2 diabetes, after a multidisciplinary medical assessment.

View details

Gastric Botox Injection

A non-surgical endoscopic procedure that temporarily slows stomach emptying and supports appetite control in eligible patients, as part of a nutrition plan.

Bariatric Candidate Assessment criteria

BMI is a clinical screening reference, not automatic approval for treatment. The assessment considers weight history, related conditions, reflux, previous procedures, anaesthetic risk, nutritional status, treatments already tried and the patient's ability to follow the recommended follow-up.

Body mass index (BMI) and metabolic profile are assessed together as initial screening references; no single value amounts to automatic approval.

Multidisciplinary medical assessment (surgical, anaesthetic and nutritional), with other specialties (cardiology, pulmonology, endocrinology, gastroenterology or psychology) added according to individual clinical needs.

No active substance misuse and no severe untreated psychological conditions that could affect surgical safety or adherence after the procedure.

An informed commitment to follow lifestyle recommendations, the staged diet and nutritional follow-up after the procedure.

Frequently Asked Questions

What is bariatric surgery?
Bariatric surgery includes laparoscopic procedures designed to reduce stomach capacity or change the digestive route in eligible patients with severe obesity or related metabolic conditions. The procedure is selected individually after medical assessment.
What is the difference between surgical and non-surgical options?
Surgical procedures (Gastric Sleeve, Gastric Bypass) change the anatomy of the stomach and require a hospital stay and general anaesthesia. Non-surgical options (Gastric Balloon, Gastric Botox) are temporary or endoscopic, involve no incisions, and have different indications and durability profiles.
Does BMI alone decide whether I am eligible for treatment?
No. BMI is only an initial screening reference. Final eligibility depends on your full medical history, any related conditions (comorbidities), your general health and the anaesthetic and surgical assessment.
How can reflux influence the choice of procedure?
A history of gastroesophageal reflux disease (GERD) is an important factor. In some patients, Gastric Sleeve can worsen existing reflux. With severe or erosive reflux, the surgical team may recommend assessing Gastric Bypass as an alternative.
How does the assessment start if I live abroad?
The assessment starts remotely: you share your medical details, health history and recent test results. The medical team at the partner hospital reviews the documents before your trip to Istanbul is confirmed.
When do I receive the medical plan and final price?
The written medical plan and final price quotation are provided after the treating team has fully reviewed your medical file. They state the recommended procedure, the hospital, the coordination services included and any exclusions.
When are the hospital and medical team confirmed?
The hospital and medical team are selected according to the recommended procedure and the confirmed medical plan. The details are shared with you before you travel.
How long do I need to stay in Istanbul?
The length of your stay in Istanbul is set individually, based on the procedure, your clinical progress and the medical team's recommendation. The estimated period is confirmed in the treatment plan before you travel.
How does follow-up continue once I am back home?
After discharge and your return home, you receive remote coordination support and structured nutritional guidance so that your progress can be followed over the long term.
What information should I prepare for the assessment?
It helps to prepare your current height and weight, your history of previous weight-loss attempts, a list of current medications, any history of reflux or diabetes and any recent medical test results.
