Gastric balloon results and aftercare, what to expect.
The honest version of life with a gastric balloon. The rough first days, the diet that follows, the weight loss that is realistic, removal, and the part that decides everything: what you do after the balloon comes out. Information only. We never name a clinic.

What happens with a balloon?
A soft balloon sits in your stomach for roughly six months, helping you feel full on less food, then it is removed. The first few days are often uncomfortable, with nausea and cramping that usually settle within a week or two. Most people lose around 10 to 15 percent of their total body weight over the period, but the result lasts only if the eating changes stick after the balloon comes out.
The figures here are indicative and drawn from reputable medical and consumer sources, reviewed July 2025. Your own result depends on how closely you follow the diet and support programme. The balloon is a tool, not a cure.
Rough start, then a routine.
Expect the first week to be the hardest. After that, the balloon works in the background while you follow a structured diet.
The first days. Nausea, cramping, and a constant feeling of fullness are common as your stomach adjusts, and for some people this lasts up to a week or two. Teams usually prescribe medication in advance to manage it. You start on liquids and build up slowly.
The diet that follows. Most programmes move from liquids to soft foods and then to small, balanced meals over the first weeks. Eating slowly, in small portions, and staying hydrated are central. The balloon does not stop you eating high calorie foods, so the eating plan does the real work.
Ongoing support. Good programmes include dietitian and behaviour support across the months the balloon is in place. Ask what support is included, because it strongly affects the outcome.
Indicative guidance, reviewed July 2025. Follow the specific diet your own provider gives you.
Real, but modest and temporary.
Over the period the balloon is in place, the average reported weight loss is around 10 to 15 percent of total body weight, with most of it in the first few months. That is a meaningful change for many people, but it is smaller than surgery and the figures vary widely between individuals. Most weight loss happens early, then tends to plateau, which is normal.
After removal. The balloon is taken out at around six months, usually during a short endoscopy, and you may go back to liquids or soft foods for a day or two while your stomach settles. This is the decisive moment: people who keep the new portion sizes, activity, and habits tend to hold or even improve their result, while those who return to old patterns often regain weight.
Set expectations honestly. A balloon is a temporary head start, not a permanent fix. If your goal needs larger or lasting loss, discuss whether other options suit you better before committing.
Who supports you for six months?
The balloon stays in for months and must be removed on time. That makes follow up the weak point of having it done abroad.
A balloon needs monitoring while it is in place and a planned removal at the end. Severe or lasting vomiting, persistent pain, or signs that the balloon may have deflated all need prompt medical attention, since a deflated balloon can move and cause a blockage. This is why the support around the device matters as much as the placement itself.
If you have a balloon placed abroad, think hard about the six months that follow. Ask who provides the diet and behaviour support, who you contact if you cannot keep food down or develop severe pain, where and by whom the balloon will be removed, and what that removal costs and whether it is included. Travelling back for removal, or arranging it locally, needs planning before you start. A plan that covers only the placement leaves the longest and most important part uncovered.

The things everyone asks.
How much weight will I lose with a gastric balloon?
On average around 10 to 15 percent of total body weight over the months it is in place, though the range is wide. These are indicative figures reviewed July 2025, and the result depends on the eating changes you keep afterwards.
Why do I feel so sick at first?
Nausea and cramping are common as the stomach adjusts and can last up to a week or two for some people. Teams usually prescribe medication to manage it. Tell your provider if it is severe or does not settle.
How long does the balloon stay in?
Most balloons are designed to stay for around six months and are then removed, usually during a short endoscopy. Leaving one in beyond its intended time is not safe, so removal must be planned.
Will the weight come back after removal?
It can. The balloon is temporary, so people who keep the new portion sizes and habits tend to hold their result, while those who return to old patterns often regain. The habit is the real result.
What should I plan if I have it abroad?
Plan the whole six months, not just the placement. Confirm who provides diet support, who you contact in an emergency, and where and by whom the balloon will be removed, including the cost.
