gastric balloon

What is a gastric balloon?

A gastric balloon is a soft silicone balloon, that is inserted via the mouth and the oesophagus into the stomach.

The gastric balloon constantly fills a section of your stomach, without you noticing anything. This balloon makes you feel satiated, making it easier to limit the amount of food you eat and to learn a new dietary pattern. Your body gets used to eating less, making it easy to keep up even after the gastric balloon has been removed.

Compared to other methods, the gastric balloon is a highly secure method to quickly and drastically reduce stomach capacity. There is no operation needed. Care Clinic will gladly help you in your fight against the kilos.

The gastric balloon is suitable for those who have tried everything to lose weight but have put back on more weight afterwards. The gastric balloon is also suitable for those who have extreme obesity, and do not wish to choose for a surgical procedure. You can have a gastric balloon inserted when your BMI is no less than 29.

How is a gastric balloon fitted?

This is a non-surgical procedure – with no incisions and no general anaesthetic. However, your throat will be numbed with a local anaesthetic first, after which you will receive a mild sedative. The gastric balloon is then inserted.

To begin with, a small camera which is attached to a small tube is inserted via the mouth and used to check that the oesophagus, diaphragm and stomach are okay. Once everything has been checked and is okay, then the insertion of the gastric balloon will begin. The empty, rolled-up gastric balloon is inserted into the stomach via the mouth using a ‘filling tube’. The tube is then filled with 500ml of physiological saline solution. Afterwards, the balloon is closed and the procedure is complete.


‘Bariatrics’ is the collective term for all procedures used to treat obesity. Such as the gastric balloon, gastric band, gastric sleeve and the gastric bypass.

We fully understand that it is a huge step to make an appointment for a bariatric procedure. Therefore, you can expect our full support in this – if you would like, of course. We advise you to bring your partner or a good friend with you to the first consultation.

During the first consultation, we will discuss everything to do with the procedure. First of all, we will discuss with you what disturbs you the most about your body and what you would like to have changed. Also, we will discuss the methods and surgical techniques used and inform you which are the most suitable for you. But also what results you may expect, what the possible risks are and the aftercare. You will always receive an honest opinion and will be informed clearly about the procedure and period afterwards.

During the consultation, the consultant will look to see if you are a suitable candidate for the bariatric surgery you have chosen. The surgeon will ask you some questions regarding your health, medical background and any medicines you may be using. Should you use blood thinners, then you should stop taking these at least one week before the procedure.

You will be able to make the right choice after this first consultation. We understand it’s a lot of information to absorb. Therefore, do not hesitate should you wish to contact us again after this consultation with more questions.

What are the advantages of a gastric balloon?

  • It is possible from a BMI of 29
  • The balloon fills up 80 per cent of the stomach
  • You will lose about 15 per cent of your body weight without an operation.
  • A gastric balloon is safe and has little to no side effects.
  • You will get used to a healthier lifestyle and as a result, can maintain your weight, even after the program has finished.
  • You will enjoy eating and being active again.

What can I expect after the insertion of a gastric balloon?

You will remain in the recovery room for at least two hours after the operation is completed. As soon as your bodily functions are doing well and the doctor has cleared you for discharge, you may go home. Please note that for the first week after the surgery, you may not drive yourself unless otherwise indicated by the doctor.
Do not use any dangerous machines in the first week either. Do not use any tobacco, drugs or drink any alcohol.

Smoking narrows the blood vessels and can prevent the wound from healing properly, or it can affect the overall recovery. That’s why it is advisable to stop smoking for four weeks before and for four weeks after the surgery.

The body has undergone treatment and needs to recovery in its own time. The length of recovery is different per person, but it always takes time. We’ve bundled together the most important guidelines for after the surgery in our folder Living guidelines after bariatry.

The day after the operation you will be contacted by the support team from Care Clinic. They will make an appointment with you for two weeks later, for the first check-up. Six months after the insertion, you will have an appointment with the doctor to have the gastric balloon removed. This time length has been chosen because the manufacturer guarantees that the gastric balloon will not leak during this period. Should the gastric balloon remain longer, and start to leak, caused by the effects of stomach acid, then the fluid will naturally exit the body.

Each body is unique. This also means that everybody loses weight in his or her own way and time.  We cannot guarantee how much weight you will lose in the first half-year. Of course, you will eat less than before; however, it’s more about the type of food you consume.

Also, we advise you to exercise sufficiently during this process for a more beautiful and speedier result.

The average weight loss with a gastric balloon is 15 to 20 per cent of your body weight, that is if you stick to the guidelines. It is, therefore, possible to lose about 20 kilos in 3 months with the gastric balloon.
