When you opt for Wellness Kliniek, you will be treated in our high-quality clinic in Genk, Belgium. Patients travel here from Belgium, Germany, France, the United Kingdom and many other parts of the world to obtain the best possible care and the safest surgical methods. After you’ve had your gastric sleeve procedure, you’ll need to stay overnight in the clinic. After the operation, you will be invited back a few times, allowing us to offer you the highest quality aftercare tailored to your body and condition.
