Revision after stomach surgery in Dortmund: consultation at Westfalenklinik

Stomach surgery is an important step, but not always the last one. Sometimes the weight comes back or never falls far enough, sometimes complaints arise such as dumping syndrome after a gastric bypass or reflux after a gastric sleeve. At Westfalenklinik in Dortmund we advise you on this together with Weight Doctors, who have their obesity centre Dortmund in the same building. In their specialist consultation, the causes of your complaints are clarified in a targeted way and a solution is developed, an endoscopic procedure or corrective surgery. This also applies if your first operation took place at another clinic.

For your appointments, you come to Westfalenklinik at Rosemeyerstraße 2–4, directly on the B1/A40, in the immediate vicinity of the Signal Iduna Park. By car, leave the B1 at the Dortmund-Hombruch exit and park on the building’s parking deck directly in front of the entrance. From the main station, take the U45 to Stadtgarten and then the U42 to Theodor-Fliedner-Heim. You can read more on how to get here under Directions. The consultation is also possible by phone or by video; you attend the examinations and the aftercare in Dortmund.

Why a revision can make sense

Obesity is a chronic disease that often needs long-term, multi-stage treatment. Complications or insufficient weight loss after stomach surgery are not uncommon and not a personal failure. Even a well-performed operation only works as well as aftercare and everyday life allow; often, however, there are medical reasons:

  • Anatomical changes

    The stomach, the pouch or the connection to the small intestine (anastomosis) can widen over time, so that the restriction decreases.

  • Hormones and metabolism

    The body adapts and defends its usual set point, measurably and in many cases treatably.

  • Living circumstances

    Everyday life, stress, medication or new phases of life influence the course.

  • High-calorie drinks

    They simply flow through a gastric sleeve and are hardly slowed down by the narrower shape.

Besides weight gain, dumping syndrome and reflux, the concerns of the consultation also include swallowing disorders, vomiting, problems with a gastric band such as slipping (slippage) or migration, chronic pain and food intolerances.

Weight gain after stomach surgery

After the initial success, the weight comes back completely or partially for some patients, or it does not go down far enough from the start. This is more common than most people think and is only rarely due to a lack of discipline: every stomach reduction changes the anatomy, and this can change again over time. Typical signs are that you can eat larger portions again, the feeling of fullness decreases, cravings return and your weight has been rising again for months.

Endoscopy and imaging are used to measure whether and how much the stomach, pouch or anastomosis have widened. This determines the route that is an option for you:

  • Endoscopic reduction

    An enlarged pouch or a widened anastomosis is reduced again from the inside, minimally invasively and without another open operation.

  • Re-⁠sleeve

    If the gastric sleeve has widened again, it is surgically reduced once more and the restriction is restored.

  • Conversion to a bypass

    If the effect of the gastric sleeve wears off, switching to a bypass procedure may be an option.

  • Bypass revision

    The limb lengths or the anastomosis are adjusted to strengthen the restriction and the metabolic effect.

In addition, medically supervised GLP-1 therapy can help to stabilise your weight. How much weight you lose again after a revision depends on the cause and the procedure and cannot be guaranteed in advance.

Dumping syndrome after gastric bypass

After a gastric bypass, food reaches the small intestine more quickly. In some patients, this can lead to dumping syndrome, that is circulatory and digestive complaints that make eating, and with it everyday life, a burden. This is a known side effect and is treatable. Two forms are distinguished, and many of those affected have elements of both:

  • Early dumping

    shortly after eating, triggered by emptying into the small intestine too quickly, with nausea, a racing heart, sweating, dizziness, abdominal cramps or diarrhoea.

  • Late dumping

    one to three hours after eating, triggered by reactive low blood sugar, with trembling, cravings, weakness or problems concentrating.

The complaints occur above all after sweet or carbohydrate-rich meals and can range up to fainting spells and circulatory collapse. A dumping score, a glucose tolerance test and an endoscopy show the form and the cause.

The first step is always adapted eating habits with a fixed meal structure and little sugar; nutritional advice can support you with this. If that is not enough, an anastomosis that is too wide can be reduced endoscopically so that the stomach pouch empties more slowly; a bypass revision is an option as a surgical route.

Reflux after gastric sleeve

After gastric sleeve surgery, reflux can occur in some cases, or existing reflux can become worse. The narrow gastric sleeve no longer has a reservoir, and the pressure inside it is higher. Often a hiatal hernia is added, in which part of the stomach slides upwards through the opening in the diaphragm and which sometimes already existed unnoticed before the operation, or a narrowing (stenosis) in the sleeve. Typical signs are persistent heartburn and acid regurgitation, burning behind the breastbone especially when lying down and at night, difficulty swallowing, an irritable cough, hoarseness or a lump in the throat.

Persistent, untreated reflux can damage the oesophagus in the long term. Acid blockers relieve the symptoms but do not remove the cause; anyone who takes them permanently without things really getting better should have the source of the reflux investigated. The core of the diagnostics is gastroscopy, supplemented if necessary by an examination of swallowing or a pH measurement. Depending on the findings, gentle endoscopic and minimally invasive procedures are an option, or the conversion of the gastric sleeve into a gastric bypass, which can also support weight loss.

Your path to revision

This is how a revision proceeds if you are advised in Dortmund:

  1. Step 1

    Beforehand

    Consultation in Dortmund. In person at Westfalenklinik, by phone or by video: we discuss your complaints, your medical history and your previous operation. You can book your appointment online.

  2. Step 2

    Analysis

    Your medical history. Experienced specialists clarify what the cause could be, whether a corrective procedure makes medical sense, which procedure is suitable and whether German statutory health insurance can cover the costs.

  3. Step 3

    Diagnostics

    Targeted examinations. Endoscopy, radiological examinations such as imaging of swallowing, and functional and laboratory diagnostics are coordinated for you.

  4. Step 4

    Findings

    Cause and plan. The findings are evaluated together and the cause of your complaints is named, without assigning blame. This results in your personal treatment plan, endoscopic or surgical.

  5. Step 5

    Procedure

    The procedure in Wertheim. Procedures take place at the Weight Doctors® Nationalklinik in Wertheim, performed by specialists who specialise in obesity surgery and corrective procedures.

  6. Step 6

    Afterwards

    Aftercare in Dortmund. Check-up appointments, the app and a personal coach continue to support you. If you wish, further steps can follow, such as GLP-1 therapy for stabilisation or a tightening procedure.

What does a revision cost, and when does German statutory health insurance pay?

With a medical indication in line with the guidelines, there is a chance that German statutory health insurance will cover the costs of a revision, for example with documented weight gain with a proven cause, with proven reflux or with dumping syndrome that does not improve sufficiently with conservative measures. For cost coverage by statutory health insurance, a multimodal concept is generally required, a six-month preparation programme that is not itself covered by health insurance. There is no prior application: Weight Doctors check all requirements before the procedure, organise the appointments and then bill your health insurance directly.

Without cost coverage, the treatment is possible as a self-pay service. The price depends on the procedure and is discussed with you in the consultation; financing is possible through our financing partner. You can read more about the requirements under Costs and German health insurance.

Frequently asked questions

What is a revision after stomach surgery?

A revision is a further bariatric procedure for people who have regained weight, not lost enough weight or suffer from complaints after previous stomach surgery. Depending on the cause, it is carried out surgically or endoscopically, from the conversion of a gastric sleeve into a gastric bypass to correction from the inside.

Did I do something wrong?

No. Obesity is a chronic disease with many influencing factors. Complications or insufficient weight loss after stomach surgery are not a sign of personal failure but require targeted further medical treatment.

I had my operation at another clinic. Can I still come?

Yes. The consultation is open to everyone, regardless of where the original procedure took place, even if it was abroad.

Why have I regained weight after stomach surgery?

Usually the gastric pouch, the connection to the small intestine (anastomosis) or the gastric sleeve has widened again, so that the restriction decreases. Hormonal adaptations and metabolism also play a role, as do stress, medication or new phases of life. The diagnostics look for the specific cause in your case.

Is a correction possible without another major operation?

In many cases, yes. An enlarged pouch or a widened anastomosis can often be reduced again endoscopically, that is from the inside and without an incision. The diagnostics show whether this is possible in your case.

What is dumping syndrome?

A known side effect after a gastric bypass. Because food reaches the small intestine more quickly, circulatory and digestive complaints can occur after eating, from nausea and a racing heart to low blood sugar. It only occurs in some patients and is treatable.

Do I have to take acid blockers permanently after a gastric sleeve?

Not necessarily. If the cause of the reflux is removed, many patients no longer need the acid blockers afterwards. That is exactly the aim of the treatment.

Which procedures are an option for a revision?

Surgically, for example, a re-sleeve, conversion to a gastric bypass, a bypass revision or restoring the restriction; endoscopically, reducing the pouch or anastomosis and other minimally invasive revision techniques. The diagnostics clarify which procedure is suitable for you.

Where does the procedure take place?

Procedures take place at the Weight Doctors® Nationalklinik in Wertheim, the Weight Doctors centre for obesity surgery. You can attend the consultation, the preliminary examinations and the aftercare at Westfalenklinik in Dortmund; the consultation is also possible by phone or by video.

Does German statutory health insurance cover the costs of a revision?

With a medical indication in line with the guidelines, there is a chance of cost coverage by German statutory health insurance, for example with documented weight gain with a proven cause, with proven reflux or with dumping syndrome that does not improve sufficiently with conservative measures. There is no prior application. All requirements are checked for you before the procedure, and you do not have to speak to your health insurance yourself.

Do I need a multimodal concept again before a revision?

For cost coverage by German statutory health insurance, a multimodal concept is generally required, a six-month preparation programme. It is a prerequisite but is not itself covered by health insurance. The appointments are organised for you.

What does a revision cost?

That depends on the procedure and on whether German statutory health insurance covers the costs. Without cost coverage, the treatment is possible as a self-pay service; we discuss the price with you in the consultation, and financing is possible through our financing partner.
