Gastric balloon: an overview of risks, methods, aftercare and costs
Fed up with diets that lead to the yo-yo effect? The gastric balloon is seen as a minimally invasive aid to weight loss – without the need for surgery. But what’s really behind it?
Being overweight and obesity are now among the most common health challenges in Germany. Many of those affected have already tried numerous diets – often with short-term success followed by the yo-yo effect. Against this backdrop, the gastric balloon is becoming increasingly important: as a minimally invasive aid to weight loss, without surgery and without irreversible anatomical changes.
However, the gastric balloon is not a „shortcut to your dream figure“. Rather, it is a temporary medical aid designed to make it easier to embark on a sustainable weight-loss programme. This guide takes a comprehensive look at the topic: from the medical basics, through the various methods and the exact treatment procedure, to the risks associated with a gastric balloon, costs and aftercare.

What is a gastric balloon, and who is it suitable for?
A gastric balloon is a soft silicone balloon that is temporarily placed in the stomach, where it takes up space. This means the stomach can hold less food, a feeling of fullness sets in sooner, and daily calorie intake is automatically reduced. Depending on the model, the balloon is either inserted endoscopically or swallowed, and remains in the body for several months.
How does weight loss work with a gastric balloon?
The gastric balloon works in several ways:
- Mechanical: Less room in the stomach → smaller portions
- Physiological: Faster feeling of fullness, altered sense of hunger
- Behavioural: Support with changing eating habits
It is important to note that:
The gastric balloon does not treat the cause of excess weight, but rather supports a period of learning and reorientation. That is why the accompanying dietary advice is a key component of the treatment.
Who is a gastric balloon suitable for?
A gastric balloon is particularly suitable for people who:
- are significantly overweight,
- would like to avoid an operation (e.g. gastric bypass),
- are prepared to make lasting changes to their lifestyle.
Overview: Suitability by BMI
| BMI / Criterion | Assessment & Suitability |
|---|---|
| 27–30 | Possible in the presence of additional risk factors |
| 30–35 (Class I obesity) | A common main target group for medication-based support |
| > 35 | Only in selected cases (often consider surgical options) |
| Eating disorders | Clear exclusion criterion |
| Lack of cooperation | Not suitable (compliance is crucial) |
Important to know
A gastric balloon is no substitute for motivation or therapy. Without active participation and a change in diet, long-term success will be limited.
A comparison of the various methods of gastric balloon treatment
There is no single „gastric balloon“; rather, there are several medically distinct systems that differ significantly in terms of duration, insertion procedure and aftercare. It is therefore essential to consider each one individually.
The swallowable balloon (e.g. Allurion®)
The swallowable balloon is considered the least invasive option. It is swallowed in capsule form and then filled with fluid in the stomach. An endoscopy or anaesthesia is not required.
Features of the swallowable gastric balloon:
- No surgery or gastroscopy required
- Time spent in the stomach: approx. 4 months
- Self-dissolving: The balloon is naturally passed through the body
| Advantages | Disadvantages |
|---|---|
| – Very low barrier to entry – Minimal downtime (no anaesthesia) – Ideal for first-time practitioners | – Shorter duration of action compared with other models – Volume cannot be adjusted retrospectively |
The classic 6-month gastric balloon
This procedure is carried out endoscopically under twilight sedation. The balloon is filled with saline solution, which is usually dyed blue – a safety measure designed to enable the early detection of leaks.
Typical characteristics:
- A tried-and-tested standard procedure
- Removal required after 6 months
- Close medical supervision is recommended
The adjustable 12-month balloon (e.g. Spatz3)
The 12-month balloon offers the advantage that its volume can be adjusted whilst it is in place. This allows for more personalised management of the treatment.
Special features:
- Longer-lasting effect
- Adjustment in the event of a plateau or side effects
- Higher aftercare costs
| Criterion | Swallow balloon | 6 months | 12 months |
|---|---|---|---|
| Endoscopy | No | Yes | Yes |
| Duration | approx. 4 months | 6 months | 12 months |
| Customisable | No | No | Yes |
| Aftercare | Medium | High | Very high |
| Costs | Medium | Medium | High |
Treatment procedure: From insertion to removal
The gastric balloon treatment process follows a clearly structured procedure designed to ensure medical safety and transparency for patients.
- 1. Preparation and aptitude test Medical consultation; BMI calculation and medical history; ruling out any contraindications (e.g. stomach disorders)
- 2. Insertion of the gastric balloon Swallowable balloon: administration in the clinic; endoscopic balloons: insertion under analgosedation; duration: usually 20–30 minutes
- 3. Settling-in period (first few days) During the first 3–7 days, the body often reacts with nausea, vomiting and stomach cramps. These symptoms are usually temporary and can be effectively managed with medication.
- 4. Wearing time and distance Regular check-ups; accompanying dietary advice; removal once the period has elapsed
The first 72 hours:
The initial phase is the most challenging. Close medical supervision and consistent fluid intake are crucial to avoiding complications.
Risks associated with a gastric balloon: What you need to know
The question of the risks associated with a gastric balloon is one of the most important factors for patients when making a decision. Proper patient information means clearly distinguishing between common, expected side effects and rare but serious complications. It is precisely this distinction that is missing from many hospital websites – and it is essential for making an informed decision.
Common side effects (particularly in the first few days)
During the adjustment phase, the stomach reacts to the foreign body by activating defence mechanisms. These symptoms are unpleasant, but are usually medically harmless:
- Nausea and vomiting
- Stomach cramps and a feeling of pressure
- Feeling of fullness
- Heartburn (reflux)
- General fatigue
These symptoms occur particularly during the first 3–7 days and usually subside significantly once the stomach has become accustomed to the balloon. Accompanying medication (e.g. gastric protectants, antiemetics) is standard practice.
Rare but serious complications
Genuine complications are much less common, but are medically significant. These must be discussed openly before treatment begins:
- Balloon leak or rupture: The balloon may develop a leak. Blue-coloured urine serves as a warning sign and requires immediate medical attention.
- Migration of the balloon: In rare cases, a deflated balloon may migrate into the bowel and cause an intestinal obstruction.
- Inflammation of the stomach lining (gastritis): Due to persistent irritation of the stomach lining.
- Stomach perforation: Extremely rare, but serious – usually in cases of undiagnosed pre-existing conditions or where the indication has been incorrectly determined.
Good to know
Most patients do not experience any serious complications. A thorough pre-operative assessment, the doctor’s experience and a structured aftercare programme are crucial to patient safety.
Diet and aftercare: How to maintain your weight in the long term
The long-term success of a gastric balloon does not depend on the balloon itself, but on changes to diet and behaviour both during and after the period in which it is in place. Without these measures, the risk of a yo-yo effect increases significantly.
An overview of the feeding stages
- Phase 1: Liquid phase (Days 1–7) Aim: To protect the stomach and allow it to adjust to the balloon. Permitted: clear broths and electrolyte solutions, protein shakes (with no added sugar), unsweetened tea and still water.
- Phase 2: Weaning phase (weeks 2–3) Pureed vegetables & soups, low-fat quark, yoghurt & cottage cheese, soft porridge, protein-rich pureed foods.
- Phase 3: Normal diet Focus on protein and fibre, small portions (bear in mind how full you feel), chewing extremely thoroughly, and keeping eating and drinking separate.
Further recommendations for aftercare
- Regular appointments with a nutritionist
- Eating slowly (at least 20–30 minutes per meal)
- Avoiding foods high in sugar and fat
- Psychological support for emotional eating
It’s the long term that counts
Studies show that weight loss following gastric balloon treatment is only sustained after 24 months if patients have made lasting lifestyle changes.
Gastric balloon costs: What prices can you expect?
The cost of a gastric balloon varies depending on the method, the duration of treatment and the level of care provided. Transparency is particularly important here, as this is generally a service that patients must pay for themselves.
| Method | Price range |
|---|---|
| Swallow balloon | approx. €3,000 – €4,000 |
| 6-month gastric balloon | approx. €2,500 – €4,500 |
| 12-month balloon (adjustable) | approx. €4,500 – €7,000 |
What is included in the price?
- Medical consultation and fitness assessment
- Inserting and, if necessary, removing the balloon
- Medicines (some)
- Follow-up appointments
- Nutritional advice (depending on the provider)
Will the health insurance cover the costs?
Generally speaking, no, as the gastric balloon is considered a non-surgical, temporary measure.
In very rare cases, a decision on a case-by-case basis may be possible, for example in the following circumstances:
- serious underlying conditions
- conservative treatments that have failed on several occasions
However, there is no entitlement.
Assessing costs realistically
Low-cost offers that do not include structured aftercare or dietary advice should be viewed with scepticism – in the long term, they increase the risk of failure and complications.
Safety first: Why it can be a good idea to take out insurance when having a gastric balloon fitted
A gastric balloon is considered a minimally invasive method of weight loss and is generally safe when used for the correct indications. Nevertheless, it is a medical procedure which – like any treatment – may be associated with potential risks and side effects. These include not only acute symptoms during the adjustment phase, but also rare complications that may require further medical treatment.
One aspect that must not be overlooked is potential follow-up costs. For example, if the following were to occur:
- a necessary early removal of the balloon,
- the treatment of inflammation or irritation of the stomach lining,
- hospital admission in the event of more serious complications,
Additional costs may arise which are not always fully covered by statutory health insurance – particularly if the gastric balloon procedure was carried out as a self-pay service.

Frequently Asked Questions about the gastric balloon (FAQ)
As a rule, statutory health insurance funds do not cover the costs, as the gastric balloon is regarded as a non-surgical, temporary measure. In very rare cases, an assessment on a case-by-case basis may be carried out, but there is no entitlement to cover.
The average weight loss is around 10–25 % of the initial weight. Actual results depend heavily on the individual’s commitment, dietary changes and follow-up care.
A gastric balloon is considered a relatively safe method when fitted and monitored by a professional. Common side effects, such as nausea, are usually temporary. Serious complications are rare, but should be discussed openly in advance.
If there is a leak, the urine will become discoloured by the blue filling solution. In this case, the balloon must be removed by a doctor immediately to prevent it from migrating into the bowel.
Depending on the model, between 4 and 12 months. Some swallowing balloons dissolve on their own, whilst others need to be removed endoscopically.
Yes. After the adjustment period (usually a few days), most patients are able to return to work. However, physically demanding activities should be discussed with the doctor on a case-by-case basis.
No. The gastric balloon is a tool, not a guarantee. Long-term success can only be achieved through lasting changes to eating habits and lifestyle.
Light exercise is strongly recommended. Vigorous exercise should only be resumed once the adjustment phase is over and following consultation with a doctor.
