Weight Loss Surgery in Türkiye

Weight loss (bariatric) surgery is a group of stomach-reducing procedures — including gastric sleeve, gastric bypass and the non-surgical gastric balloon — that limit how much you can comfortably eat and, in some cases, how many calories you absorb, to support major and lasting weight loss. It is intended for adults living with obesity for whom diet, exercise and medication have not brought lasting results, particularly where weight is affecting health through conditions such as type 2 diabetes or sleep apnoea. Invisicana coordinates your care end to end with experienced bariatric teams at accredited, Ministry of Health–authorised partner hospitals in Türkiye — from free medical assessment through surgery to remote dietary follow-up at home — with transparent all-inclusive packages and an honest view of what each option involves, because weight loss surgery is a lifelong commitment, not a quick fix.

Is this treatment right for you?

Suitable for: adults living with obesity, often with weight-related conditions such as type 2 diabetes, who have tried diet and exercise without lasting success and are ready to commit to lifelong lifestyle change.

Less ideal if: you are looking for a quick fix without long-term dietary change, have an untreated eating disorder or a medical condition that makes surgery unsafe, or fall outside the range at which bariatric treatment is normally considered.

Suitability can only be confirmed by a qualified clinician after assessing you, which is why every plan begins with a free, personalised review rather than a fixed promise.

Process & recovery

Gastric sleeve and gastric bypass are performed under general anaesthetic using keyhole (laparoscopic) surgery, typically taking one to three hours with a hospital stay of a few nights, while a gastric balloon is placed endoscopically under sedation in a short procedure with no incisions. Recovery follows a staged diet — liquids, then puréed and soft foods, then solids — over several weeks, and most people return to desk-based work within one to three weeks. Risks include bleeding, infection, leaks from the staple line or new join, blood clots, reflux, nutritional deficiencies and anaesthetic complications, which is why lifelong follow-up and supplements are part of every surgical plan.

Choosing between the procedures

Weight loss surgery is not one operation but a set of options, and the right choice depends on your starting point, your health and what you can realistically sustain. A gastric sleeve permanently removes a large part of the stomach, so you feel full sooner and hunger hormones are reduced; it is one of the most commonly performed bariatric procedures. A gastric bypass creates a small stomach pouch and reroutes part of the digestive tract, which limits both intake and calorie absorption and is often considered where acid reflux or type 2 diabetes is a significant factor. A gastric balloon is different again: a temporary, non-surgical device placed in the stomach under sedation and removed after a set period, which may suit people who want support with portion control without an operation, or who do not meet the criteria for surgery.

These are general guides only. None of the options works on its own — each is a tool that makes lasting dietary change more achievable, and suitability is always confirmed by a medical assessment rather than personal preference alone.

How your care is coordinated

Invisicana is a facilitator, not a hospital, and we are open about that. We coordinate your care rather than perform your surgery: your operation is carried out by experienced bariatric surgeons and their anaesthetic and nursing teams at accredited, Ministry of Health–authorised partner hospitals in Türkiye. Your journey begins with a free medical assessment — typically covering your BMI, medical history, medications and previous weight loss attempts — which the treating team uses to advise honestly whether bariatric treatment is appropriate and, if so, which procedure fits your circumstances.

If you decide to go ahead, transfers, accommodation, an interpreter and your in-hospital care are arranged as part of a transparent, all-inclusive package, and a free, no-obligation personalised treatment plan and quote are provided before you commit to anything. You can see how each stage works on our patient journey page.

Recovery and aftercare in general terms

Recovery after weight loss surgery follows a broadly similar arc whichever procedure you have. In hospital you will be encouraged to walk early to support circulation, and you will start on clear fluids. Over the following weeks you progress through a staged diet — liquids, then puréed and soft foods, then normal but much smaller meals — guided by the dietary plan you are given. Most people return to desk-based work within one to three weeks, with heavier activity reintroduced gradually. After a sleeve or bypass, lifelong vitamin and mineral supplements and periodic blood tests are essential, because the changed digestive tract absorbs some nutrients less well. Once you are home in the UK, the aftercare team follows up remotely, and we encourage you to keep your GP informed so routine monitoring can continue locally.

Life after weight loss surgery

The operation is the beginning, not the end. Most weight loss happens over the first year to eighteen months, and keeping it off depends on the habits built during that window: regular small meals, adequate protein, hydration and activity. Some people are later left with loose skin, particularly around the abdomen, arms and thighs; once weight has been stable for a sustained period, skin-removal procedures such as body contouring surgery can be considered as a separate, later step. The treating team will be honest with you about all of this from the start, because realistic expectations are the foundation of a good outcome.
