Understanding Obesity & Bariatric Surgery

Obesity is a chronic disease, not a lack of willpower.

Bariatric (obesity) surgery is a metabolic intervention that changes the anatomy of the stomach to limit food intake and reset the body's metabolic set-point. The American Society for Metabolic and Bariatric Surgery (ASMBS) calls it the most effective and long-lasting treatment for severe obesity.

Eligibility generally starts at a BMI of 40, or 35–39.9 with obesity-related conditions such as Type 2 diabetes, hypertension or sleep apnea. Wholecares coordinates gastric sleeve and gastric bypass procedures at licensed partner hospitals in Istanbul, Turkey, where a gastric sleeve typically costs €2,400–€3,500 and a gastric bypass €3,200–€4,000, with the in-patient stay and airport transfers included.

Defined by Science

Obesity is the excessive accumulation of body fat that impairs health. According to the World Health Organization, it's a complex condition influenced by genetics, hormones, and environment - often resistant to diet alone.

Primary Causes

While nutrition and lifestyle play a role, genetics are crucial. Children of parents with obesity are considerably more likely to develop it themselves. Hormonal imbalances can also slow metabolism and trigger weight gain.

What is Bariatric Surgery?

The American Society for Metabolic and Bariatric Surgery calls it the most effective and long-lasting treatment for severe obesity. Procedures like Sleeve Gastrectomy change your anatomy to limit food intake and reset your metabolic set-point.

Are You A Candidate?

Eligibility is based on Body Mass Index (BMI) and health conditions.

BMI Required For Bariatric Surgery

BMI ScoreObesity ClassSurgery Eligibility
BMI 40+Class 3 (Severe)Generally Eligible
BMI 35 - 39.9Class 2Eligible with conditions (Diabetes, Apnea, etc)
BMI 30 - 34.9Class 1Gastric Balloon or Individual Medical Review

These thresholds are general guidance. Final eligibility is determined by the treating clinician at the partner hospital after a full assessment.

"Surgery is not the 'easy way out'. It is a powerful medical tool for those fighting a biological battle."

Surgical Solutions

Advanced laparoscopic techniques for faster recovery and minimal scarring.

Sleeve Gastrectomy

The "Stomach Stapling" Method: ~80% of the stomach is removed laparoscopically. This restricts food intake and significantly reduces the "hunger hormone" Ghrelin. Ideal for volume eaters.

Gastric Bypass

A Proven Approach: Creates a small stomach pouch and bypasses part of the small intestine. It works by restriction and reducing calorie absorption. Highly effective for Type 2 Diabetes remission.

Metabolic Surgery

Diabetes Management: Specific procedures targeting metabolic syndrome to improve insulin resistance. Many people with Type 2 diabetes see their blood sugar control improve, and some achieve remission — outcomes vary with the procedure, how long diabetes has been present, and individual factors.

Why Laparoscopic (Closed) Surgery?

Partner surgeons use the latest laparoscopic techniques (small keyhole incisions) rather than large open cuts. This means:

  • Less pain and minimal scarring.
  • Faster recovery (hospital stay of just 2-4 days).
  • Reduced risk of complications.

Gastric Sleeve Cost Comparison (2026)

A gastric sleeve in Turkey costs a fraction of what the same procedure costs in the UK, the USA or Western Europe. The figures below are typical market ranges by country, not Wholecares quotes — the range in Turkey varies by hospital and by the complexity of the case. Wholecares coordinates bariatric surgery at licensed partner hospitals in Istanbul and gives you an exact figure once a surgeon has reviewed your case.

LocationAverage Price (EUR)
Turkey€2,400 - €3,500
USA€15,000 - €25,000
UK€10,000 - €16,000
Germany€11,700 - €15,000
Spain€8,000 - €14,000
France€16,000+
Italy€22,000+

What you pay

Your treatment is paid directly to the hospital — we never handle your money. Our coordination service is covered by the hospital, so you pay Wholecares nothing.

Your Recovery Happens in the Hospital, Not a Hotel

From your operation until the day your surgeon discharges you, you stay in the hospital — under the care of the surgical team, with nursing staff on the ward around the clock.

Most packages advertised for Turkey move the patient into a hotel a day or two after surgery. A hotel room, however comfortable, has no nursing staff. The bariatric packages Wholecares coordinates are built the other way round: every night you are admitted is a hospital night.

  • Doctors on the ward: your surgeon and the ward doctors follow your recovery and can respond straight away if something needs attention.
  • Nursing care around the clock: pain relief, your fluids, getting you up and walking, and your first sips and first meals are all supervised by clinical staff, day and night.
  • Discharge is a clinical decision: you leave when the treating surgeon judges you are ready, not when a hotel booking says so.

How long you stay is set by the treating surgeon and by the procedure — typically 2–4 nights. A one-month supply of vitamins and protein supplements is included in the package, with the nutrition plan you go home on.

Medical Complication Insurance:
Arranged Before You Travel

"What if something happens when I go back home?" is a valid concern, and it deserves a practical answer rather than a reassuring one. Bariatric surgery carries real risks, which your surgeon should set out with you before you agree to anything. What we can tell you is how aftercare is arranged: a medical complication insurance policy is included in the partner hospital's package, and the scope of what it covers is set out in writing in your quote.

A Medical Complication Insurance is included in the partner hospital's package; the policy is issued by an insurer, and its cover and limits are set out in the policy document. What it covers, and its limits, are set out in that policy.

Verify Coverage Details
  • Valid After You Return Home

    The policy is arranged to remain valid once you are back in your own country. The situations it applies to are set out in the policy wording.

  • Terms Set Out in Writing

    What the policy covers, and any limits, are set out in the policy document you receive before you travel.

  • Prepared Individually

    Each policy is prepared individually for you ahead of your trip, rather than as a blanket promise.

  • Financial Protection

    Cover is provided within the limits determined by the policy, which you can review before you travel.

No. You stay in the hospital from admission until your surgeon discharges you, typically 2–4 nights depending on the procedure.

Many packages advertised for Turkey move patients to a hotel a day or two after surgery, where no nursing care is available.
Is bariatric surgery in Turkey safe? +
Bariatric surgery is major abdominal surgery and carries real risks wherever it is done - leaks at the staple line, bleeding, clots and, rarely, death. No country or certificate changes that; what changes your risk is the surgeon, the hospital and what happens when something goes wrong. Wholecares coordinates gastric sleeve and bypass at partner hospitals in Istanbul licensed by the Turkish Ministry of Health and holding its International Health Tourism Authorization Certificate, using laparoscopic (keyhole) techniques; other accreditations vary by hospital and we will tell you which applies to yours. A complication insurance policy is included in the partner hospital's package, with what it covers and its limits set out in that policy. Ask your surgeon for their own complication rate and what the plan is if you need help after you fly home.
