Objective: Social support is mostly seen as a positive resource for many health outcomes. However, some research indicates that weight loss may disrupt the equilibrium of relationships and highlights the potential for a more negative form of social support. This qualitative study aimed to explore bariatric surgery (BS) patients’ perceptions of the way in which their current or previous partner supported them throughout their BS journey.

Design: BS patients (N=30) participated in remote qualitative semi-structured interviews.

Methods: The data were analysed using an inductive approach to reflexive thematic analysis. At the time of this study, patients had undergone BS a mean of 5.1 years ago.

Results: Four themes were derived from the data. While two themes reflected social support as a form of caring (Mutual Investment and Positive Reinforcements),the other two themes indicated aspects of sabotage (Feeder Behaviours and Negative Reactions to Weight Loss Attempts and Successes). Transcending these themes was the notion of Bariatric Surgery as an Opportunity or Threat to the Relationship.

Conclusions: Some patients perceived social support as a positive resource for achieving optimal clinical response post-BS. This was characterised by Mutual Investment from their partners and being offered Positive Reinforcements for changes in their weight status and wellbeing. Some, however, described more negative aspects of support which had undermined their BS goals, either unintentionally or intentionally, through acts of sabotage including Feeder Behaviours and Negative Reactions to Weight Loss Attempts and Successes. Future research should develop interventions to help prepare the partners of those undergoing BS for the changes to both their partner’s weight status and the dynamics of their relationship.
