Weight Loss Surgery Maintenance And Psychosocial Development: A Narrative Perspective, Carrie J. L. Hickman

Walden Dissertations and Doctoral Studies

Bariatric surgery is not the panacea it was once thought to be for weight loss. Due to patient noncompliance issues, many weight loss surgery patients are relapsing and regaining the significant amounts of weight that bariatric surgery had initially helped them to lose. This failure is costly monetarily, psychologically, and medically to both the patient and to society. Using the narratives of 32 post-weight loss surgery patients, this narrative study explored: (a) whether Erikson's psychosocial stages of development occur after weight loss surgery, (b) whether successful patients (defined as those who are able to maintain their weight loss long term) …
