Paths to weight loss with medical support, from the gastric balloon and the endo-sleeve to GLP-1 therapy and nutritional advice. We clarify which path suits you in a personal consultation at the Klinik am Seestern in Düsseldorf.
A balloon reduces the size of the stomach for a limited time, for 6 or 12 months, or as a capsule to swallow for about 4 months. The three balloons compared.
Overview of the endoscopic procedures for stomach reduction without an incision through the abdominal wall, from the endo-sleeve to the gastric balloon.
In the POSE® 3.0 endo-sleeve, the stomach is reduced in size from the inside with sutures during a gastroscopy; the procedure is intended to be permanent.
No-obligation guidance – does not replace medical advice. Which treatment suits you is something you clarify with your specialist in the consultation.
Weight loss in Düsseldorf: with medical support at the Klinik am Seestern
Losing weight is a long path for many people, and good intentions alone are often not enough. At the Klinik am Seestern in Düsseldorf, we support you medically together with the Weight Doctors: we examine you, discuss your goals and choose with you the path that suits your body and your everyday life. From the first consultation, a permanent contact person is at your side, and nutrition coaches help you to establish the new habits.
Consultation, treatment and aftercare take place in our specialist clinic in Lörick, on the left bank of the Rhine in the Am Seestern office district, close to the B7. The U77 runs without a change from the main station to the Am Seestern stop, and you can park free of charge on the premises.
Which path suits you?
Not every path suits everyone. GLP-1 therapy manages without a procedure. A gastric balloon reduces the size of the stomach for a few months and is possible from a BMI of 27. The endo-sleeve reduces the size of the stomach permanently during a gastroscopy, without an incision through the abdominal wall. From a BMI of around 40, stomach surgery may come into consideration, a gastric sleeve or gastric bypass; you will be advised and given aftercare for it in Düsseldorf, and the operation takes place at the Weight Doctors’ Nationalklinik in Wertheim. What they all have in common: they are aids, and whether the weight stays down depends on how you change your diet and exercise.
That is why every treatment includes support from nutrition coaching and an app, and you can also book nutritional advice on its own. We decide with you, after the examination, which path makes sense. A combination is also possible, for example GLP-1 therapy after a gastric balloon.
Methods compared
Three paths to losing weight with medical support
Without a procedure, with a balloon for a limited time, or with a permanent stomach reduction. The most important differences at a glance.
01GLP-1 therapywithout a procedure
A prescription-only active substance that you inject yourself once a week acts like the body’s own hormone GLP-1. It can reduce the feeling of hunger and empty the stomach more slowly, so that the feeling of fullness lasts longer.
A balloon is placed during a gastroscopy or swallowed as a capsule and filled with fluid in the stomach. It takes up space there, so that you feel full sooner, and is removed or excreted after 4 to 12 months.
ProcedureGastroscopy or capsule
Time in place
about 4, 6 or 12 months
Anaesthesia
twilight sedation, none for the swallowable balloon
During a gastroscopy, the stomach is gathered from the inside and sutured with anchors. Nothing is removed; the stomach retains about a quarter of its volume. The procedure is intended to be permanent.
This is how weight loss with medical support proceeds at the Klinik am Seestern in Düsseldorf:
Step 1
Beforehand
First consultation. You book online or call us. The first conversation is about your goals, your previous attempts to lose weight and your health.
Step 2
Examination
Your starting point. We determine your BMI, ask about accompanying conditions and clarify which paths come into question for you.
Step 3
Decision
Your plan. Together, you choose the path and the package that suit you, and receive a no-obligation offer.
Step 4
Treatment
The start. You begin GLP-1 therapy at home following instruction, the gastric balloon is placed on an outpatient basis, and the endo-sleeve during a gastroscopy under general anaesthesia.
Step 5
Support
New habits. Nutrition coaches, an app and follow-up appointments accompany you while you change your diet and exercise.
Step 6
Afterwards
Maintaining your weight. We see you again for aftercare. If skin is left over after a large weight loss, a tightening procedure can follow.
What does weight loss with medical support cost in Düsseldorf?
The costs depend on the path you choose. There are four packages for the gastric balloon; the standard package starts at €3,500. GLP-1 therapy starts at €330 a month, nutrition coaching at €159. For the endo-sleeve, you receive a no-obligation offer after the consultation. Financing is possible through our financing partner.
The gastric balloon and GLP-1 therapy are generally self-pay services. For a stomach reduction, German statutory health insurance can cover the costs if there is a medical indication. You will find all the details under Costs and German health insurance.
After weight loss: skin tightening at the specialist clinic
After a large weight loss, the skin often does not retract on its own, especially on the abdomen, upper arms and thighs. As a specialist clinic for plastic and aesthetic surgery, we tighten these areas in the same building in which you were supported during weight loss. You can read more about this under Skin tightening after weight loss.
What options for losing weight are there at the Klinik am Seestern?
At the Klinik am Seestern in Düsseldorf, together with the Weight Doctors, we offer GLP-1 therapy, the gastric balloon for 6 or 12 months or to swallow, the endo-sleeve as an endoscopic stomach reduction, and nutritional advice. For stomach surgery with a gastric sleeve or gastric bypass, we advise you in Düsseldorf; the operation takes place in Wertheim. After weight loss, skin tightening can follow.
Which path suits me?
That depends on your BMI, your health, your goals and whether a procedure is an option for you. In the consultation, we examine you and discuss with you which path makes sense; a combination is also possible.
From what BMI is treatment possible?
A gastric balloon is an option from a BMI of 27, the endo-sleeve as a rule at a BMI of 30 to 40. For GLP-1 therapy, the doctor decides on the basis of your BMI and weight-related conditions.
Do I need a referral?
No. You can book your consultation appointment directly online or call us.

I am a lipoedema and lymphoedema patient and have been trying to find help for about 10 years. Here it was no problem at all! I was called in quickly, was well looked after, my questions were answered very professionally, and I was able to leave the practice in tears of joy! Many thanks for the support so far.

I had my appointment at the practice for a consultation about my lipoedema, and I really want to leave a review even though I haven't had any surgery there yet. The reason is that this was the first time I felt truly taken seriously during an examination of my lipoedema. Dr. Witt was very friendly and professional from the start, and at the same time incredibly pleasant and humane. He took an exceptional amount of time, examined me very thoroughly and answered all my questions in detail. He is incredibly respectful and explains realistically what could be done and how the whole process would work. I found it particularly positive that at no point did a hectic or unpleasant mood arise. You never had the feeling of being “brushed off” or being under time pressure. Instead, the whole atmosphere was calm, relaxed and trusting. Dr. Witt was very committed, photos were taken of the affected areas and every possible treatment was explained in an understandable way. Dr. Witt explained everything in detail, yet never came across as complicated or distant. Although he is an absolute specialist in his field, I felt at all times that I could speak openly and ask any question. It felt more as if I had been a patient there for a long time. It was also particularly important to me that I never felt pushed towards an operation. It is still not at all clear whether I will have my operation at all, and yet I was taken incredibly seriously and treated with respect. That is exactly what built so much trust in me. I would also very much like to mention the lady at reception, Marris, in a positive way. She was super polite, had a very pleasant and calm manner and immediately gave me a good feeling. Although it was almost 5 p.m. and the end of the working day was approaching, she was incredibly friendly to me and did not seem at all annoyed or stressed. It is precisely such little things that make a huge difference to me personally and reinforced my positive overall impression of the practice. The practice itself is also absolutely impressive. It is extremely modern, high-quality and stylishly furnished. You feel more as if you are entering a luxury hotel than a traditional doctor's practice. Everything seems very well thought out, calm and professional. The organisation around the appointment was also excellent. Even before the appointment, communication was always very friendly, quick and professional. Questions were answered immediately and the whole process seemed perfectly organised. I was also allowed to park in the clinic's car park, which was an enormous relief since everything in the area was completely full. Although it was already later in the afternoon, Dr. Witt even personally saw to it that enquiries were made internally about my question regarding costs. Shortly after I had left the practice, I already received all the information by email. That too simply shows how professionally and attentively they work there. Overall, an exceptionally positive experience, of a kind you unfortunately only rarely have in the medical field. Absolutely fabulous.

Very beautiful clinic, wonderful reception and great service. The consultation with the doctor was very comprehensive and she addressed all my questions, which is all you could wish for as a patient / customer. I will definitely have my treatment done here.

Everything was great, just one small remark..... I didn't get any dinner/bread in the evening. The most important thing for me was the operation, or rather everything around it.

I was welcomed and advised incredibly kindly. The consultation takes place on an equal footing and without medical jargon, and what I like best is that they paid attention to what the best treatment is for my concern, and not to what would earn the practice the most money. I took a week to think it over, but actually the decision to choose the clinic was made much sooner.

I had a consultation and felt taken seriously and understood. They took a lot of time for me, and the examination and the conversation were very thorough. In the end, the treatment is too expensive for me, so I won't be able to have it done.

I really liked the super friendly manner of the ladies at reception, and also that the doctor took the time to see and advise me, as well as the nice lady who went through the cost plan with me. I felt wonderfully looked after and will definitely have my treatment there. Thank you once again for everything so far.

I was welcomed very nicely. The doctor was also very nice and answered all my questions. She also showed understanding that one does not decide straight away.

Dr. Bromba's calm, matter-of-fact manner and his competence really convinced me during the consultation.
