'We're outside the norm again because of the thing that allowed us to be inside the norm': An interpretative phenomenological analysis of the experience of developing an alcohol use disorder after bariatric surgery.

Studies indicate that bariatric surgery is associated with an increased risk of alcohol use disorder (AUD). It is considered some patients develop the disorder after surgery, without having antecedents of preoperative alcohol problems. This qualitative study aimed to explore the experiences of people who developed AUD postoperatively and understand how they make sense of the onset of this disorder. A semi-directed interview was carried out with eight adults who had undergone bariatric surgery and developed AUD de novo postoperatively. Data were analysed using interpretative phenomenological analysis. Four superordinate themes emerged: (1) 'losing control over drinking and self after surgery'; (2) 'feelings of guilt, shame and loss contrasted with perceptions of still being lucky'; (3) 'trying to make sense of the onset of AUD'; and (4) 'retrospective evaluation of bariatric surgery and preoperative information'. These themes indicated loss of control was a central aspect of participant's experiences of postoperative alcohol consumption. AUD was associated with negative emotions and cognitions, but several participants still considered themselves lucky. All tried to make sense of this disorder's onset; many felt they would not have developed AUD if they had not undergone surgery. The onset of AUD influenced their current perceptions and feelings about surgery and the preoperative information regarding AUD risks. Taken together, these results provide insight into the subjective experience of suffering from new-onset AUD post-surgery. However, more studies are necessary to gain a better understanding of the physical and psychological implications of postoperative AUD.
