Short answer
A gastric balloon is a soft silicone balloon placed in the stomach through the mouth with an endoscope, then filled with saline so you feel full sooner. The procedure usually takes 20-30 minutes under sedation, with no incisions and typically a stay of 2-3 days in Istanbul. The balloon is temporary, usually removed after 6-12 months, and lasting results depend on the diet changes you make while it is in place.
What is a gastric balloon?
A gastric balloon is a temporary weight-loss device that takes up space in the stomach. It is placed through the mouth using a thin camera tube called an endoscope, so there is no surgery and no scarring.
Once in place, the balloon is filled with sterile saline. It makes you feel full after smaller portions and slows how fast the stomach empties. It is designed as a tool to help you change your eating habits, not a permanent solution on its own.
Who is it for?
A gastric balloon is often suitable for adults with a BMI of around 27-30 or more who have not lost enough weight with diet and exercise alone. It can also be used to reduce weight before another operation, or for people who do not want or are not suitable for surgery.
A doctor assesses your suitability in person. A balloon is usually not advised if you have had previous stomach surgery, a large hiatus hernia, stomach ulcers, are pregnant, or need to take certain blood-thinning or anti-inflammatory medicines.
- BMI around 27-30 or above
- Prefers a non-surgical option
- Ready to follow a structured diet plan for 6-12 months
How the procedure is done
The balloon is placed under sedation and the procedure typically takes 20-30 minutes. The doctor passes the endoscope into the stomach, positions the deflated balloon and fills it with saline before removing the tube.
You rest for a few hours under observation and usually go back to your hotel the same day. Your hotel, VIP transfer and medical interpreter are arranged before you land, and a check-up is done before you fly home.
Recovery and results
The first three to five days are usually the hardest, as the stomach gets used to the balloon. Nausea, vomiting and cramps are common at first and are managed with medication and a fluid-only diet.
Most patients then move to soft food and normal textures within two to three weeks. Weight loss is typically gradual over the months the balloon is in place. Keeping the weight off after removal depends on the habits you build, which is why your Metropolmed dietitian follows you for six months.
Your dietitian plans each stage of your diet with you and checks your progress online. Regular contact makes it easier to keep going when motivation dips, and most patients find this support is what helps the new habits last.
Risks and safety
A gastric balloon is less invasive than surgery, but it still has risks. Nausea and vomiting in the first days are very common, and a small number of patients cannot tolerate the balloon and need early removal. Less common risks include reflux, stomach ulcers, dehydration, balloon deflation and, rarely, blockage of the bowel.
The balloon must be removed at the time your doctor advises. If you notice blue or green urine, which can signal a leak in some balloon types, or severe pain or vomiting, you should contact your coordinator straight away.
