Gastric balloon in Turkey | Procedure, results & costs

What is a gastric balloon, and how does it work?

A gastric balloon is a soft, expandable silicone or polyurethane sphere that is placed inside the stomach via a thin endoscope, a flexible tube that is passed through the mouth and down the oesophagus. No incision is required. No staples. There is no rerouting of the digestive system.

Once the balloon is in place, it is filled with sterile saline (typically 400–700 ml, depending on the model) or, in some cases, air. The inflated balloon occupies a significant portion of the stomach cavity, creating a constant sense of fullness that naturally reduces portion size at every meal.

Over time, this constant early satiety helps patients to build new eating habits, especially when supported by proper nutritional guidance. The balloon usually remains in place for six to twelve months, providing a structured timeframe for sustainable change.

At the end of the treatment period, the balloon is removed through the same endoscopic route. This quick procedure (usually under 20 minutes) is performed under light sedation.

Who is a good candidate? BMI criteria and realistic expectations

A gastric balloon is best suited for patients who need structured support to lose weight but are not ready for or do not qualify for surgery.

• BMI range: Ideal candidates have a BMI of 25–40 (optimal 27–35); not suitable if below 25 or above 40.
• Previous weight loss attempts: Good candidates have tried diet and exercise without lasting results; unsuitable if no serious lifestyle attempts have been made.
• Relationship with food: Suitable patients are ready to work with a nutritionist and improve habits; unsuitable if there is an active, uncontrolled eating disorder.
• Medical history: Candidates should have no prior gastric surgery, no active ulcer or severe GERD; not suitable with a history of gastric surgery, severe hiatal hernia, or active oesophagitis.
• Life stage: Best suited for patients who are not pregnant or breastfeeding; not suitable for current or planned pregnancy within 6 months.
• Motivation: Suitable candidates are committed to 6–12 months of follow-up and lifestyle changes; not suitable if seeking a passive, effortless solution.

In short: this is not a quick fix, it's a guided reset tool for motivated patients.

According to the World Gastroenterology Organisation, intragastric balloons are recommended for patients with a BMI ≥27 who have not achieved sufficient results with lifestyle interventions.

Contraindications: when the balloon is not the right option

A responsible clinic will screen for these before accepting any patient. If you have any of the following, the balloon will likely not be recommended, and there are usually better alternatives:

• Prior gastric surgery (sleeve, bypass, gastric band),anatomy no longer suitable
• Active peptic ulcer or severe erosive oesophagitis, balloon worsens mucosal damage
• Severe hiatal hernia (>5 cm),significantly increases reflux and complication risk
• Uncontrolled eating disorder involving purging, risk of premature balloon expulsion
• Inflammatory bowel disease (Crohn's disease),risk of obstruction
• Coagulation disorders or anticoagulant therapy (that cannot be paused),bleeding risk
• Pregnancy or planned pregnancy within the treatment period
• Chronic liver disease or cirrhosis, impairs post-procedural recovery
• Psychological instability or inability to commit to follow-up, significantly reduces outcomes

If you have one or more of these contraindications, it does not necessarily mean weight loss intervention is off the table; it may mean a different approach is more appropriate. Our medical team can assess and suggest alternatives (endoscopic plication, sleeve gastrectomy, medical obesity management) based on your full history.

The procedure in Turkey: what actually happens, step by step

Knowing exactly what to expect removes a lot of the anxiety around this kind of decision. Here is a frank, step-by-step description of what a standard gastric balloon placement looks like at one of our partner clinics in Istanbul:

1. Pre-op consultation (Day 1): Blood tests, an ECG if needed, a brief endoscopy to confirm no ulcers or contraindications, and a meeting with the dietitian to establish your baseline and post-op plan.
2. Sedation (Day 2, morning): You receive a mild intravenous sedative, not general anaesthesia. You are drowsy but can breathe independently. The whole experience is similar to a colonoscopy in terms of depth of sedation.
3. Balloon placement (20–30 minutes): The deflated balloon is passed through the mouth via a thin endoscope and positioned in the stomach. Once confirmed in place, it is filled with 400–700 ml of sterile saline (for saline models). You will feel full as the balloon inflates; this is normal.
4. Recovery in clinic (2–4 hours): You rest in a monitored room while the sedation wears off. A nurse monitors your vitals and manages any early nausea with IV medication if needed. An X-ray confirms balloon position.
5. Overnight hospital stay: Clinic protocols in Turkey typically include one night of medical supervision. Meals during this period are clear liquids only. Most patients feel well enough to walk around by the evening.
6. Pre-flight consultation (Day 3): A final check before travel. Your dietitian provides a personalised meal plan for the first 4 weeks. You receive emergency contact details and your full procedure report in English.
7. Follow-up from home: Regular video check-ins with the clinical team are scheduled at weeks 2, 4, 8 and then monthly. Many patients also have a local GP follow-up. Turquie Santé provides a translated medical report to share with your doctor at home.

Types of intragastric balloon available in Turkey

Not all gastric balloons are the same. They differ in how they are inserted, how long they stay in, and how they are removed, and those differences matter depending on your profile, schedule, and tolerance for procedures. Here is a clear comparison of the six main systems available through Turquie Santé's partner clinics:

TBW = Total Body Weight. Figures drawn from published studies: Orbera (Ponce et al., Obesity Surgery 2015); Spatz3 (Brooks et al., Endoscopy 2014); Allurion (Raftopoulos et al., Obes Surg 2017); Heliosphere Bag (Cioeta et al., Obes Facts 2019). Individual results vary.

Post-operative follow-Up

Following gastric balloon placement, an overnight hospital stay under medical supervision is required to ensure a safe recovery. During this time, close medical monitoring and nutritional management are essential, especially during the early stages of your recovery. An x-ray check will be performed to verify the correct positioning of the balloon to ensure smooth operation throughout the procedure.

For best results, patients should follow a balanced diet after the gastric balloon procedure. For the first few weeks, the diet should consist mainly of liquids, then semi-liquids, before gradually returning to a normal diet after the fourth week. This transition is essential to ensure good tolerance of the balloon and to prevent any digestive complications. A dietitian from the hospital in Turkey will help you adjust your meals to ensure a smooth, controlled transition to a solid diet.

Some patients may experience mild nausea the day after the procedure, but these symptoms are usually temporary and do not interfere with a rapid return to a more varied diet.

Gastric balloons are designed to remain in place for 6 to 12 months. It is important to adhere to this time frame to prevent long-term complications and maximize the benefits of the procedure.

Results of gastric balloon

Combined with dietary changes and regular physical activity, the gastric balloon procedure usually results in significant weight loss. On average, patients lose between 10% and 15% of their total body weight, which can be as much as 10 to 15 pounds in four months.

However, results vary depending on factors such as lifestyle, commitment to a weight management program, eating habits, and exercise. In addition to weight loss, the gastric balloon is designed to help patients adopt new eating habits, improve portion control, and change their relationship with food. It serves as a support tool to facilitate long-term lifestyle changes.

Risks and side effects: real frequencies

A gastric balloon is among the safest bariatric interventions available, but that does not mean risk-free. Here is what the evidence actually says:
