Your guide

The gastric balloon at a glance

What you should know before making your decision – from the principle and the wearing time to the different balloons and what it can do for you.

Temporary stomach reduction: how the gastric balloon works

Reaching your desired weight and keeping it permanently only works with a balanced diet and enough exercise. In everyday life, it is often the other way round: too little exercise, together with unfavourable eating habits – and weight rises. This is where the gastric balloon comes in: as a temporary, minimally invasive stomach reduction, without a strict diet and without surgery, both of which can put a heavy strain on the body.

A soft silicone balloon is brought into the stomach via the mouth and oesophagus and filled there, usually with about 500 ml. It is then about the size of a grapefruit and takes up around a third of the stomach. It is available for 6 months or 12 months and as an Allurion gastric balloon for about 4 months.

  • The balloon works from day oneBecause less room is left in the stomach for food, you can only eat smaller portions, feel full sooner and stay full for longer; the feeling of hunger can decrease. Many experience this as a boost that motivates them to lose weight. At the end of the wearing period, the balloon is removed without leaving any residue.
  • The balloon is a temporary aidIt can make it easier for you to change your diet, but does not replace this – what matters is what you make of this time. How it is placed in the stomach is shown in the explainer film below; you can find more films in our media library.

Benefits of the gastric balloon

  • No incision and no scarsThe balloon reaches the stomach via the mouth; there are no incisions and no scars.
  • Only temporaryThe balloon stays in the stomach only for the wearing period and is then removed without residue – nothing is left behind in the long term.
  • No long-term medicationOnce the first phase after insertion is over, you no longer need to take any medication for the balloon; its possible side effects are therefore also avoided.
  • Adjustable fill volume (Spatz3)With the adjustable Spatz3, the fill volume can be adjusted, recommended after about 12 weeks: smaller if it is uncomfortable, larger if weight loss is low.
  • Also swallowableFor the Allurion gastric balloon, you need neither endoscopy nor anaesthesia.
  • App and digital scaleThe Weight Doctors® App with a digital scale is included; your values flow directly into the app, and our team can see your progress.

Who is the gastric balloon suitable for?

The gastric balloon is intended for adults with excess weight or early-stage obesity. Depending on the balloon, it is possible from a BMI of 26: the balloon for 6 months up to a BMI of about 35, the one for 12 months up to about 40. The BMI calculator shows you where you stand. In addition, the following applies:

  • If you have not made progress so far with conservative methods of weight loss
  • If you are ready to change your diet and take part in medically supervised therapy
  • Which balloon and which wearing period suit you depends on weight and BMI – we clarify this honestly in the consultation
  • Not the first choice with a higher BMI or if you want a permanent solution – the endoscopic stomach reduction Weight Doctors SLEEVE® or weight-loss surgery with Weight Doctors BARIATRICS® are then more likely options. A route with no procedure at all is the medically supervised Weight Doctors® GLP-⁠1 pharmacotherapy, and without medication, Weight Doctors® hydroGMA.

How the treatment works

The real work begins with the insertion – our team accompanies you from start to finish. This is how the treatment typically works:

Endoscopy team at work, with the doctor holding the endoscope in the foreground
  1. ConsultationIn a personal conversation, we discuss the exact procedure. Your treatment plan is based on your wishes and your initial findings.
  2. PlacementUnder sedation (twilight sleep) or brief general anaesthesia, the balloon is introduced into the stomach via the mouth and filled; this takes about 20–25 minutes. After about an hour of recovery, you can go. You swallow the Allurion gastric balloon as a capsule.
  3. Getting used to itIn the first days, the stomach gets used to the balloon: nausea, stomach cramps and vomiting are possible. Drink plenty then and follow the recommendations of your specialist; prescribed medication can ease the symptoms. This phase is generally over after about 5 days.
  4. SupportDuring the wearing period, you change your diet – smaller portions, new habits – supplemented by exercise therapy. We accompany you throughout, including via the Weight Doctors® App.
  5. RemovalAt the end of the wearing period, the balloon is removed endoscopically via the mouth and oesophagus; the body passes the Allurion gastric balloon out naturally. The new habits remain – the app, coaches and aftercare accompany you afterwards as well.

How safe is the gastric balloon?

Because there is no cutting or stitching, no wound has to heal, and many risks of an operation do not apply. With the Spatz3, an anchor system is also intended to prevent the balloon from slipping into the intestine should it ever deflate; the empty balloon can then be replaced by gastroscopy.

All balloons we use bear the European CE mark; for gastric balloons, Weight Doctors® is a premium partner of the supplier Medispar. They are placed by experienced specialist doctors – Prof. Dr. med. Deniz Uyak, for example, has been supporting patients with the gastric balloon since 2007 and has carried out around 5,000 procedures.

What can I achieve with the gastric balloon?

How much weight you lose depends on the balloon and on you. The weight-loss goal is up to 10 kg with the Allurion gastric balloon, up to 20 kg with the balloon for 6 months and up to 30 kg with the balloon for 12 months. Results vary from person to person – your specialist will discuss with you what is realistic for you.

The greatest difference is made by the habits you build during this time. We therefore accompany you with nutrition tips and exercise therapy, and on request with personal nutrition coaching. You can read more about the support under Weight Doctors® 360°.

Frequently asked questions

Questions about Weight Doctors® GASTRIC BALLOON

Your question isn’t listed? Your specialist will take time for it during the consultation.

Is the gastric balloon better than a diet for losing weight?

The gastric balloon can be great support in losing weight. A significant weight loss is possible within a short time, and changing your diet can become easier for you. The balloon can also help reduce cravings.

How long does the gastric balloon stay in the stomach?

Depending on the model, about 4 months (Allurion gastric balloon), 6 months or 12 months. Which wearing period suits you depends mainly on your BMI and your weight-loss goal – we discuss this in the consultation.

How much weight can I lose with a gastric balloon?

Depending on the balloon, the weight-loss goal is up to 10 kg (Allurion gastric balloon), up to 20 kg (6 months) or up to 30 kg (12 months); with the adjustable Spatz3 also above that. Results vary from person to person and depend heavily on how consistently you change your diet.

How long does insertion take?

About 20–25 minutes, as an outpatient under sedation (twilight sleep) or brief general anaesthesia. After around an hour of recovery, you can go home. You swallow the Allurion gastric balloon, by contrast, as a capsule – without general anaesthesia, in about 15–20 minutes.

Does insertion hurt?

The pain is slight, because you sleep or doze during the short procedure; with the Allurion gastric balloon, no anaesthesia is needed at all. For many, the first days afterwards are more noticeable, until the stomach has got used to the balloon.

Is wearing the gastric balloon a nuisance?

Usually only in the first days, while your stomach gets used to the balloon. After that, you notice it mainly in that you can feel full sooner.

When am I socially presentable again?

Generally after 3–4 days. Work and everyday life are then usually possible again; even so, plan for some rest in the first days after insertion.

Can the size of the balloon be changed?

With the adjustable Spatz3, yes: by gastroscopy, the fill volume can later be reduced if the balloon causes discomfort, or increased if you are losing less weight than hoped. With the other models, the fill volume stays the same.

Is there a risk of the gastric balloon slipping into the intestine?

The adjustable Spatz3 has a special anchor system. It is intended to prevent the balloon from slipping into the intestine and causing an intestinal obstruction, for example if it deflates. The empty balloon can then be replaced endoscopically via the mouth and oesophagus. The other balloon models have no anchor system.

How is the gastric balloon removed again?

The same way it was inserted: endoscopically via the mouth and oesophagus, as an outpatient and under sedation. The Allurion gastric balloon deflates by itself after about four months and is passed out naturally.

Will scars remain?

No. The balloon reaches the stomach via the mouth; there is no cutting. After removal, nothing is left behind in the body.

What do I need to contribute to the success of the treatment?

The balloon can help you change your diet in the long term. What matters is that you give up unfavourable habits. We give you tips on how this can succeed permanently, and our app-based coaches accompany you in life after the stomach reduction as well.

How do I keep my weight once the balloon is out again?

What matters are the habits you build during the wearing period. The Weight Doctors® App, your coach and aftercare accompany you afterwards as well. For some people, medically supervised GLP-⁠1 therapy can make sense afterwards – more in the article GLP-⁠1 after gastric balloon or endo sleeve.

What does a gastric balloon cost?

Weight Doctors® GASTRIC BALLOON is available from £4,250. The exact price depends on the balloon and the wearing period; the Weight Doctors® App with a digital scale is included. Payment in instalments via Ideal4Finance is possible. All prices at a glance: Costs & prices.
