What Vitalys does

Vitalys is a Netherlands-based specialized bariatric clinic that treats adults with obesity through surgical, pharmacological, and lifestyle interventions. Founded in 2008 and operating as an integrated unit within top clinical hospital Rijnstate, it is one of the largest bariatric surgery clinics in the country, performing approximately 1,350-1,500 procedures annually. Its core products include gastric bypass, gastric sleeve, SADI, mini bypass, and revision surgeries performed using minimally invasive (laparoscopic) techniques, alongside the COOL lifestyle intervention, a medication-based weight loss program (with approximately ten-month waiting time), and gastric balloon procedures. The clinic also operates a multidisciplinary Expertisepoli Bariatrie bringing together bariatric surgeons, internists, gastroenterologists, psychologists, and dietitians for complex cases, and runs an active research program with six full-time researchers collaborating with Wageningen University & Research, Radboudumc, and other academic centers. Vitalys has been recognized as an IFSO Centre of Excellence and reports patient outcomes of 92.6% achieving more than 20% weight loss after gastric bypass (versus a 91.6% national average), with patient satisfaction rated 8.8/10 on Zorgkaart Nederland.

The business model is professional services delivered directly through owned clinic locations in Elst (headquarters), Hoogeveen (satellite), and Arnhem (within Rijnstate hospital). Revenue is generated from healthcare services covered by Dutch health insurance under standard medical coverage; Vitalys holds 2026 contracts with all major Dutch insurers including Menzis, Zilveren Kruis, CZ, ONVZ, Salland, DSW Stad Holland, Zorg en Zekerheid, VGZ, ASr, and Caresq. Patient acquisition is primarily referral-based through general practitioners, supplemented by direct outreach via monthly information sessions (online via Microsoft Teams and in-person), a Quickscan online assessment tool, patient testimonials, and earned media coverage. The clinic is led by General Director Claudia de Swart and Medical Director Wouter Vening, with research led by Prof. Dr. Eric Hazebroek. No external funding or private equity backing is disclosed; ownership remains within the Rijnstate hospital system.
