Neighbouring provinces

Aftercare from Zeeland
Follow-up after the operation lasts five years or longer. Vitalys, as an example, sees patients at 6, 12 and 18 months, then once a year until year five, and takes blood at every visit. A lot of centres mix appointments in person with online contact. If you live in Zeeland and are comparing centres, find out which check-ups can happen remotely and how to reach the centre outside office hours. After the aftercare period ends, you keep taking WLS vitamins for life and have a blood test every year, in most cases through your GP.
How many people in Zeeland have obesity?
The Health Monitor (RIVM, GGDs and Statistics Netherlands) found that 15.6 percent of the adult Dutch population had obesity in 2024, with GGD regions differing between 11.6 and 19.2 percent. Multiplying this by the some 192,269 inhabitants of the places mentioned above leads to a rough upper limit of about 30,000 people with obesity. It is a maximum because children are included in the inhabitant numbers, whereas the percentage only refers to adults. vzinfo.nl publishes the regional figures.
Surgery is open to only some of these people. The criteria: a BMI of 40, or 35 if you also have a weight-related condition such as sleep apnoea, high blood pressure or type 2 diabetes. For the rest, a supervised medication plan, a gastric balloon or a lifestyle programme might be a better match. An overview is on the page treatment options for obesity.
Getting weight loss surgery from Zeeland: step by step
- Register with a GP in your municipality; the GP is the gatekeeper for hospital care.
- Check your insurance: is NOK Terneuzen contracted by your insurer, or another centre that suits you better?
- Go to an information session. These are frequently held online, so check whether one is offered in English.
- Screening by an internist, psychologist and dietitian.
- Operation and aftercare: after a brief admission, check-ups continue for a minimum of five years. How long it takes to travel from Zeeland to the centre therefore counts.
Choosing a centre as a resident of Zeeland
There is no obligation to use the centre most people from your town go to.
