Gastric balloon in Turkey: indications, results, risks and prices

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

A gastric balloon is a soft silicone or polyurethane sphere placed inside the stomach. For an endoscopic balloon, a flexible tube (endoscope) is passed through the mouth. No incision is required and the digestive tract is not rerouted.

Once in place, the balloon is filled with sterile saline (the volume depends on the model) or, in some cases, air. It occupies part of the stomach, which can help you feel full with smaller portions.

Depending on the model, the balloon stays in for about 4 to 12 months. It is then removed by endoscopy or, for the swallowable balloon, it empties and is eliminated naturally. Results depend on dietary support and lasting changes in eating habits.

Who is a good candidate? BMI criteria and realistic expectations

A gastric balloon suits adults who need structured support to lose weight but do not want or need surgery.

• BMI: about 27 to 40 depending on the model (Orbera: 30 to 40 per the FDA).
• Previous attempts: diet and exercise without lasting results.
• Relationship with food: willingness to work with a dietitian; not suitable with an active, uncontrolled eating disorder.
• Medical history: not suitable after gastric surgery that changed the anatomy, or with an active ulcer, severe reflux, a large hiatal hernia or active esophagitis.
• Pregnancy: not suitable during pregnancy or breastfeeding.
• Commitment: follow-up and lifestyle changes for the whole period the balloon is in place.

It is a temporary tool, not a quick fix. A consultation with a bariatric specialist or gastroenterologist decides whether it is suitable for you.

Contraindications: when the balloon is not the right option

A clinic should screen for these before accepting a patient. With any of the following, the balloon will probably not be recommended, and other options may be better:

• Previous gastric surgery that changed the anatomy.
• Active peptic ulcer or severe erosive esophagitis.
• Large hiatal hernia.
• Uncontrolled eating disorder involving vomiting.
• Inflammatory bowel disease (Crohn's disease),because of the risk of obstruction.
• Bleeding disorders, or anticoagulant therapy that cannot be paused (the prescribing doctor decides).
• Pregnancy or planned pregnancy while the balloon is in place.
• Severe liver disease.
• Inability to commit to follow-up.

Having a contraindication does not mean weight-loss treatment is off the table: other approaches (endoscopic plication, sleeve gastrectomy, medical management of obesity) may be more appropriate. Your doctor decides after a full assessment.

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

The exact steps depend on the clinic and the balloon model. In general:

1. Pre-procedure assessment: medical history, blood tests and, if needed, an endoscopy to rule out an ulcer or another contraindication, and a meeting with the dietitian.
2. Sedation: for an endoscopic balloon, you receive sedation or, sometimes, general anesthesia. The swallowable balloon (Allurion) is swallowed without anesthesia.
3. Balloon placement (about 20 to 30 minutes): the balloon is passed through the mouth with an endoscope, placed in the stomach and filled. You may feel full as it inflates.
4. Recovery in clinic: a few hours of monitoring. Nausea is managed with medication.
5. Overnight stay: not always needed. Some clinics keep patients one night to control nausea.
6. Before you fly: your doctor confirms when you can travel and gives you a written report and the dietitian's meal plan.
7. Follow-up from home: ask the clinic how follow-up with the team is organized after you return, and keep a local doctor informed.

Types of intragastric balloon available in Turkey

Gastric balloons differ in how they are inserted, how long they stay in and how they are removed:

Obalon (swallowed balloons) and Heliosphere Bag (air-filled) have unconfirmed availability: Obalon stopped activity in 2021, and Heliosphere had lots withdrawn for early deflation (BfArM, 2009) and is not FDA-approved. Ask the clinic which exact model is offered.

Post-operative follow-Up

After placement, most patients go home the same day after a few hours of monitoring; one night of observation is sometimes recommended to control nausea. For the swallowable balloon, an X-ray confirms its position before it is filled.

Diet: a liquid diet for the first 24 to 48 hours, then progressive textures over a few weeks, according to your team's instructions. Ask whether dietitian follow-up is included and whether it continues after you return.

Nausea, vomiting and cramps are common in the first days and are managed with prescribed medicine. Tell your doctor in case of severe pain, repeated vomiting or blue or green urine.

Depending on the model, the balloon stays in for about 4 to 12 months. Respect the planned duration to limit complications.

Results of gastric balloon

Combined with dietary changes and regular physical activity, the gastric balloon can help you lose weight. In a meta-analysis of 44 studies of the Orbera balloon, average weight loss was 13.2% of total body weight at 6 months. Individual results vary a lot and are not guaranteed.

The balloon is a temporary tool to help with portion control and new eating habits. Medical and nutritional support is essential to maintain results after removal: part of the weight may be regained.

Risks and side effects: real frequencies

Most gastric balloon side effects are temporary, but rare and serious complications exist. Their frequency varies with the model and the study.

• First days to weeks: nausea, vomiting, abdominal cramps and bloating, very common. They are managed with anti-nausea medicine, antispasmodics and stomach protection.
• Acid reflux and heartburn.
• Early removal if symptoms persist or you cannot tolerate the balloon.
• Balloon deflation, with a risk of migration and bowel obstruction. Blue or green urine can be a warning sign for some saline balloons: see a doctor at once.
• Ulcer, bleeding and, very rarely, gastric perforation. FDA safety communications (2017-2020) also reported spontaneous hyperinflation and acute pancreatitis.

Seek urgent care in case of severe abdominal pain, repeated vomiting, fever or if you stop passing gas and stool.
