A systematic review of patient and clinician experiences of bariatric tourism.

Background: Although bariatric surgery is highly cost effective, accessing this treatment in the UK and other western nations is often challenging. Patients are therefore increasingly engaging in bariatric health tourism despite its associated risks and warnings from health institutions. A systematic review was performed to assess the reasons why patients are travelling abroad for surgery and common practices among bariatric tourism service providers.

Methods: Medline and PubMed were searched for articles analysing the experiences of patients and service providers. Articles published in English between 2010 and 2023 were considered and seven were included for review after title, abstract and full text analysis.

Results: Four studies assessing patients' experiences and outcomes following bariatric tourism and three examining the perspectives of bariatric service providers were reviewed. Patients across the studies were mostly from western Europe, North America and the Middle East. The most common reasons for pursuing bariatric tourism were a lack of bariatric service provision in patients' home nations, high costs of surgery in the private sector and long waiting times. Examples of practice outside the scope of most internationally recognised guidelines were identified across multiple studies, especially regarding patients' pre-operative optimisation and follow-up. The studies therefore suggest that bariatric tourism may lead to significant health risks and issues that need managing once patients return home.

Conclusions: Bariatric tourism is a common practice with significant associated risks. The reasons underpinning its appeal however, reflect genuine problems with accessing bariatric services and a lack of pre-operative education and optimisation.
