Gastric Balloon Hamburg

Gastric Balloon in Hamburg

Successfully lose weight in the long term

Welcome to the specialized internal medicine practice in Hamburg. My name is Dr. med. Mathias Kahl and I am pleased that you have found your way to this page.

Losing weight is a topic that has accompanied me all my life. Every person reacts differently to the food they eat. However, modern approaches such as DNA metabolic analysis usually leave patients alone with the findings. Standard diets such as SlimFast, OptiFast, Weight Watchers and Intermittent Fasting also usually only bring results for a short period of time. The reason? You give up the things you love under certain circumstances.

And that’s what makes the intragastric balloon such a great invention. With the support of the intragastric balloon and their personal aftercare coach, patients can lose 1-2 kilos per week and up to 35 kg in a year. The personal weight loss coaching ensures that you do not go on a diet, but learn to eat consciously. Because it is often the old wisdom that is true: The dose makes the poison.

How do I lose weight with a gastric balloon?

The gastric balloon can help patients lose weight successfully in two ways. In your stomach, it stimulates important nerves that are responsible for your feeling of fullness. You get full much faster and you get hungry much less quickly.

The intragastric balloon supports you from the first day of therapy. You will be permanently full from much smaller and healthier portions. Together with your personal aftercare advisor, you can use the therapy to find your way back to healthier eating habits.

Especially in the initial period, patients lose an average of 1.5-2 kilos per week. This provides many moments of happiness and motivates patients so much that they are able to take back control of their lives and their weight bit by bit in the course of therapy.

Diets are only fun as long as they work. With the gastric balloon in Hamburg, this effect can last for several months and lead to a permanent change in lifestyle.

Am I suitable? Yes, if you are...

  • ...lose a couple of kilos,
  • ...and want to lead a healthier life
  • ...want to lose weight and without costly surgery
  • ...get rid of concomitant diseases like diabetes,
  • ...or want to declare war on the yo-yo effect
  • ...your BMI is above 28


How works the therapy?

The gastric balloon is inserted into the stomach during a gastroscopy. Gastroscopies are routine procedures that are performed many 10,000 times in Germany. The procedure is therefore quite simple and painless. You simply sleep through the procedure. After just 20 minutes you wake up and start your journey to your desired weight. You will still be a little dazed and will stay in our practice for a little while for observation. Already after about an hour you can go home again.

Now the start of your new life begins! For the next 6 or 12 months, the gastric balloon will make you feel full much faster and hungry less quickly. The Weight Buddy System ensures that you are never alone! In regular meetings we ensure together that you can make the most of your therapy!

Together with your aftercare advisor, you will work out your long-term dietary changes until it has “clicked”. Because we know from our gastric balloon experience in Hamburg that you can only benefit from the gastric balloon in the long term with personal care.

Getting used to the gastric balloon

The first days

After the balloon is inserted, you will feel a little uncomfortable for 2-4 days. During the first few days, you may experience discomfort similar to the stomach flu. This includes discomfort, heartburn or nausea. But don’t worry – you will already leave our practice with all the important medications that can make your settling in more comfortable. In addition, your personal contact will talk to you on the phone every day and give you tips on how to make your acclimation a more pleasant experience.

  From a BMI of 28 the gastric balloon is interesting for you

If you suffer from severe inflammation in the digestive tract or have already had previous operations in the stomach, you are unfortunately not suitable for the gastric balloon method. Other exclusion criteria include blood clotting disorders, diseases of the kidneys, lungs or liver, as well as psychiatric diseases and drug problems. Pregnant and breastfeeding women are also not suitable for the gastric balloon method.

Yes. The method is recommended for people over the age of 18.

If the parents agree, the balloon can be used even under 18 years.

The process

Your question is a valid one. When we started offering gastric balloon therapies years ago, there were only a few providers. Currently, there are very many providers, some of which offer weight loss with the intragastric balloon very favorably.

If you want to lose weight successfully in the long term and stay slim even after the gastric balloon has been removed, I advise you to be careful. Crucial for your start into your new slim life is personal care by nutrition specialists. If you choose a low-cost provider, this care is usually missing. The consequence? Shortly after the removal, you usually gain weight again. Put your trust in us. For over 20 years, we have been improving care and weight loss results patient by patient.

Congratulations, if you have decided to have a gastric balloon, your new life will start immediately. In this case, please write us an email or call our hotline again if you have further questions or would like to make an appointment for a consultation.

Next, we meet in person at my practice in Hamburg. We will talk together about your personal medical history and clarify whether a gastric balloon can help you. At the end of this clarification, you will still have some time to think about it, at least 24 hours before the procedure.

The big day!

On the day of the procedure, please remain fasting. You will be put into a twilight sleep and wake up after 20 minutes with your new companion. You will still be somewhat dazed and will not be allowed to drive afterwards.

During the therapy you will be contacted and advised by our nutrition specialists at regular intervals – or you can of course contact them yourself. If you opt for a yearly balloon, we can add some more liquid to the balloon after a few months so that you can lose more weight than with other providers.


Intragastric balloons are also convincing in the specialist literature: in various studies, weight loss successes of 13-30 kg within 6 months have been determined. The successes are also in line with our experience from over 25 years with the intragastric balloon. With the annual balloon, which is refillable, you can even lose significantly more weight.

A gastric balloon alone will help you lose a lot of weight very quickly. However, the successes are short-lived if you are not accompanied by specialists during the therapy. Through the accompaniment of our nutritionists, you will finally make the jump from the yoyo trap and can be successfully slim in the long term.

The balloon occupies a large part of your stomach. As a result, you are already full from smaller meals and thus reduce your excess weight from the first day of the insertion. If you permanently change your diet and integrate more exercise into your daily routine or add fitness training that suits you, you can lose up to 35kg of excess weight in twelve months with gastric balloon therapy.

The treatment costs for the gastric balloon are as follows and are unfortunately not covered by health insurance in most cases:

Gastric balloon 6 months Gastric balloon 12 months
Total costs (material costs for balloon, instruments, accompanying medication and examination) 3.200,- 4.490,-

Cost refill

Cost refill of a gastric balloon used elsewhere


1.200,- incl. 6 months Nutritional advice

Cost of removal of a gastric balloon used elsewhere (e.g. from abroad) 1.200,- 1.200,-

There is no standard plan, each patient has his own eating culture!

Our Weight Buddies® are at your side during the entire wearing period and help you with individual nutritional advice to your weight loss success. In any case, it is important to permanently change your previous dietary and lifestyle habits in order to achieve the desired success. Together we can permanently reduce your excess weight, even after the removal of the intragastric balloon. Since we are very familiar with the special problems of our patients, we will find an individual way to your weight loss success.

Gastric balloon therapy in itself carries very few risks. During the insertion and removal of the balloon, you will be put into a light twilight sleep. This means that the risk of anesthesia is negligible.

In the rarest of cases, the balloon may leak, causing the blue-colored saline solution to escape. However, this is not dangerous and you can detect the leakage by the green discoloration of your urine. This can happen if the balloon remains in the body longer than the prescribed wearing time of six or twelve months and the material becomes tired.

After insertion of the balloon, you may experience mild discomfort such as malaise, heartburn, abdominal pain, nausea or vomiting during the first few days. The stomach must first get used to the balloon and tends to produce more stomach acid than usual at first. To help you get used to the balloon, we will prescribe pain-relieving medication and, if necessary, help with bridging infusions during the initial period. During the entire therapy period, we are available around the clock to answer your questions.
