Weight loss surgery in Turkey
Weight loss surgery — also called bariatric surgery — helps people living with significant obesity lose weight and improve or resolve related health conditions when diet, exercise and medication have not been enough on their own. It is not a shortcut or a cosmetic procedure. It is a serious operation with real risks, real benefits and a genuine commitment attached, and the clinics worth trusting are the ones that treat it that way.
If you are considering surgery abroad, this page explains the main procedures, who they suit, and what responsible care actually involves — so you can tell a proper medical service from a package deal.
Is bariatric surgery right for you?
Surgery is generally considered for adults whose weight is affecting their health and who have tried other approaches without lasting success. Suitability is assessed on your body mass index (BMI), your weight-related health conditions — such as type 2 diabetes, high blood pressure or sleep apnoea — and your readiness for the lifestyle changes that make surgery work.
Just as importantly, a responsible surgeon assesses whether surgery is not right for you: unstable medical or psychological conditions, or an unwillingness to commit to lifelong dietary changes, are reasons to pause rather than proceed. Honest assessment protects you.
The main procedures
Gastric sleeve (sleeve gastrectomy). The most commonly performed bariatric operation. A large portion of the stomach is removed, leaving a smaller, sleeve-shaped stomach. You feel full sooner and hunger hormones are reduced. It is permanent.
Gastric bypass. The stomach is divided into a small pouch and reconnected to the small intestine further down, which both restricts intake and changes how calories and nutrients are absorbed. It is often chosen for higher BMI or where type 2 diabetes is a factor.
Gastric balloon. A non-surgical, temporary option. A soft balloon is placed in the stomach (and removed after several months) to reduce capacity and support weight loss during a defined period. It suits people who are not candidates for, or not ready for, surgery.
Which procedure fits you is a medical decision made with a surgeon, based on your health and goals — never a default package.

Sleeve, bypass or balloon — compared
Each works differently and suits different people. This is an overview; the right choice is a medical decision made with a surgeon.
| Procedure | How it works & who it often suits |
|---|---|
| Gastric sleeve | Removes part of the stomach so you feel full sooner and hunger signals fall. The most common operation; permanent. Often a first choice across a range of cases. |
| Gastric bypass | Creates a small stomach pouch and reroutes the intestine, restricting intake and changing absorption. Often considered for higher BMI or where type 2 diabetes or severe reflux is a factor; permanent. |
| Gastric balloon | A soft balloon placed temporarily in the stomach (removed after several months). Non-surgical; suits people not ready for, or not candidates for, surgery. |
Safety and aftercare
Bariatric surgery is major surgery, carried out at Acıbadem — an accredited private hospital in Istanbul — under general anaesthesia. It carries the risks of any abdominal operation, which a qualified surgical team manages with proper assessment, monitoring and follow-up. For operations of this kind, complication cover is now a standard part of responsible practice in Turkey.
The part too many “packages” ignore is aftercare. Weight loss surgery changes how you eat for the rest of your life, and the first year needs structured nutritional guidance, vitamin supplementation and follow-up. Ask any clinic exactly what support you receive once you fly home — a good answer is specific, not vague.
Travelling for treatment
A typical stay is longer than for cosmetic procedures, because early recovery and checks happen before you fly — usually several days to a week, confirmed in your plan. The package should cover the surgery, hospital stay, hotel, transfers, an English-speaking coordinator and structured follow-up. Prices in Turkey are typically well below UK, EU and North American levels, but with an operation this significant, the surgeon and the aftercare matter far more than the headline figure.

Frequently asked questions
How do I know if I qualify?
Suitability is based on your BMI, weight-related health conditions and readiness for lifestyle change, assessed by a surgeon. Send your details for an honest opinion.
Which procedure is right for me?
There is no single right procedure — sleeve, bypass and balloon suit different people. A surgeon recommends the right option based on your health and goals.
Is it permanent?
Gastric sleeve and bypass are permanent; the gastric balloon is temporary and removed after several months.
Is weight loss surgery safe?
It is major surgery with real risks, made much safer by a qualified surgical team, a proper hospital and structured follow-up. Honest clinics discuss the risks openly.
What aftercare will I get?
Responsible care includes nutritional guidance, supplementation advice and follow-up through the first year. Always confirm the specifics before booking.
How long do I stay in Turkey?
Usually several days to a week, so early recovery and checks happen before you travel home.
What BMI do I need to qualify?
Surgery is generally considered at a BMI of 40 or more, or 35 or more with a weight-related condition such as type 2 diabetes, high blood pressure or sleep apnoea. Some guidelines consider it from a BMI of 35 (or lower with metabolic disease). Final eligibility is an individual medical decision made by a surgeon — these figures are a guide, not a promise.
Gastric sleeve or bypass — what is the difference?
The sleeve reduces stomach size; the bypass also reroutes the intestine to change absorption. The bypass can suit higher BMI or significant diabetes or reflux, while the sleeve is simpler — a surgeon advises based on your health.
Will I have loose skin after major weight loss?
Many people do, and body-contouring surgery can address it later once weight is stable — see arm lift, thigh lift and tummy tuck.
