The gastric balloon is the non-surgical member of the weight-loss family we arrange. A soft silicone balloon is placed into the stomach by endoscopy — through the mouth, under light sedation, with no incisions — and inflated so it takes up space, helping you feel full sooner and eat less. It stays in for about six months and is then removed the same way. Because there is no cutting and nothing is permanently changed, it is lower-risk and far quicker to recover from than surgery. But it is also more modest in what it achieves, and it is temporary — so it suits a particular kind of patient. We are honest about that distinction before you decide.
At the accredited partner hospitals we work with, the balloon is placed by experienced endoscopists in a hospital-grade facility, with the dietitian support that turns six months of a balloon into a lasting change.
How the gastric balloon works
The balloon works by restriction alone:
- It occupies part of the stomach, so smaller meals leave you satisfied.
- That fullness gives you a six-month window to retrain your portions and habits with the dietitian.
- Because nothing is cut or re-routed, there is no malabsorption — and so, unlike the gastric sleeve and gastric bypass, no lifelong vitamin requirement.
The honest limitation is built into how it works: when the balloon comes out, the restriction goes with it. The weight you keep off depends entirely on the habits you built while it was in.
Are you a candidate?
The balloon suits different patients from surgery. It is usually considered when:
- Your BMI is around 27–30 or above but below the threshold where surgery is recommended, or
- You want a non-surgical first step, or are not ready for permanent surgery, or
- You have a very high BMI and the balloon is used as a bridge — a way to lose some weight first so that later surgery is safer.
It is not for everyone: a small number of people cannot tolerate the balloon, and certain stomach conditions or previous stomach surgery rule it out. Your suitability is confirmed by the partner team after an assessment, and the NHS guide to weight-loss surgery is a useful independent reference on where non-surgical options fit.
Gastric balloon vs sleeve vs bypass
The three procedures are not interchangeable. This is the short version of how they compare; each page goes deeper.
| Gastric balloon | Gastric sleeve | Gastric bypass | |
|---|---|---|---|
| Surgery? | No surgery — endoscopic, temporary | Keyhole surgery, permanent | Keyhole surgery, permanent |
| How it works | Balloon fills part of the stomach | Removes ~80% of stomach | Small pouch + re-routed intestine |
| Best for | Lower BMI, or a first step / bridge | BMI 35+, most patients | Higher BMI, reflux, type-2 diabetes |
| Typical loss | ~10–15% of total body weight | Higher, sustained | Highest, sustained |
| Lifelong vitamins | No | Yes | Yes, strictly |
| Indicative from | €1,800 | €3,000 | €3,800 |
If you have severe obesity or a weight-related illness, surgery will almost always achieve more — and the balloon alone may under-deliver. If your BMI is lower, or you want to start without an operation, the balloon is the gentler, reversible choice. We will tell you honestly which group you fall into.
The procedure, step by step
- Assessment. Medical history and any needed checks confirm the balloon is suitable.
- Light sedation. You are sedated for comfort — this is not general anaesthesia, and you are not fully asleep for long.
- Placement. Using an endoscope passed through the mouth, the deflated balloon is positioned in the stomach and filled (usually with saline). The procedure takes around 20–30 minutes.
- Observation. You are monitored for a short period and given medication to ease the early adjustment.
Removal, about six months later, is the same quick endoscopic process in reverse.
Recovery timeline
- Days 1–5: The adjustment period — nausea, cramping and fullness are common as your stomach gets used to the balloon, managed with medication. This is the hardest stretch.
- Week 1: Symptoms settle for most people; you move from fluids to soft food under the dietitian’s plan.
- Weeks 2–24: You eat smaller portions comfortably and use the window to rebuild your habits. This is where the work — and the weight loss — happens.
- Around month 6: The balloon is removed by endoscopy. The habits you have built carry the result forward.
We plan a short 2–3 night stay in Istanbul for placement, as it involves no surgery and a quick recovery.
The commitment that makes it work
This is the part that decides whether the balloon is worth it. Because it is temporary, the balloon does not change your weight on its own — it buys you six months in which change is easier. To keep the weight off you need:
- A genuine change to how you eat, built during the six months with the dietitian, so it outlasts the balloon.
- Honest expectations — results are more modest than surgery, and weight is easily regained if old habits return once the balloon is out.
- Follow-up support, which we coordinate, to help the new habits stick.
If you are hoping the balloon will do the work for you, it will not — and we would rather say so now. Used as a tool with a real plan behind it, though, it can be an effective, low-risk start.
Risks and side effects
The balloon is much lower-risk than surgery, but it is not risk-free:
- Nausea, cramping and reflux, especially in the first week — common and usually temporary.
- Intolerance — a minority cannot adjust to the balloon and need it removed early.
- Deflation or, rarely, migration of the balloon — which is why it must be removed on schedule and not left beyond its rated life.
- Rare complications such as stomach irritation or, very rarely, obstruction.
Placement and removal by an experienced endoscopist in an accredited facility, with proper aftercare, keeps these risks low. As with any procedure, an honest assessment of whether the balloon is right for you matters more than the price.
Cost of a gastric balloon in Turkey
The gastric balloon in Istanbul starts at an indicative €1,800 — the most affordable of the three options, because it involves no surgery — typically all-inclusive of placement, the short stay, hotel and transfers. That is well below UK pricing for a comparable, accredited procedure. As with everything here, the figure is a starting range rather than a fixed quote; your firm price follows the team’s review of your case and confirmation that the balloon is suitable. For an all-inclusive price comparison across all three procedures, see the weight-loss surgery cost guide.
