Neighbouring provinces
If a centre in a neighbouring province is closer to your home or better suits your insurance, you can also look there. Utrecht borders Flevoland, Gelderland, South Holland, North Holland, North Brabant. Each province page lists its centres and their 2024 volumes.
Aftercare from Utrecht
After surgery you return for check-ups for at least five years: at Vitalys, for example, at 6, 12 and 18 months and then yearly up to five years, each with blood tests. Many centres combine visits with online contact. When choosing a centre from Utrecht, ask which check-ups can be done remotely and how the centre can be reached outside office hours. Lifelong WLS vitamins and yearly blood tests continue after the aftercare period, usually via your GP.
How many people in Utrecht have obesity?
Looking at the whole country, 15.6 percent of adults had obesity in 2024. That is the figure from the Health Monitor by Statistics Netherlands, the GGDs and RIVM, and it ranged between GGD regions from 11.6 up to 19.2 percent. For the places above, with around 1,204,055 inhabitants together, this means an indicative upper limit of approximately 188,000 people with obesity. The limit is on the high side because the percentage counts adults only and the inhabitant totals also contain children. For regional numbers, see vzinfo.nl.
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 Utrecht: step by step
- Sign up with a general practitioner in your own municipality. Hospital care is only accessible through your GP.
- Check your insurance: is St. Antonius Ziekenhuis contracted by your insurer, or another centre that suits you better?
- Take part in an information session; it is often online. Ask the centre whether it also runs one in English.
- Assessment by a dietitian, a psychologist and an internist.
- Operation and aftercare: a short hospital stay, then at least five years of check-ups, so travel time from your home in Utrecht matters.
