Surgical treatment for morbid obesity can be very effective in terms of weight loss and reduction of psychopathology. But the (re)emergence of eating problems after surgery is still poorly understood and may be underreported. We describe three cases in which eating disorder symptoms developed after bariatric surgery. The accelerated weight loss and heightened dieting restraint, as well as the systematic reminders to control the amount of food eaten which are crucial for treatment success, might trigger the development of eating disorders after surgery. Implications for pre-surgery assessment and preparation are discussed. HubMed – eating


What contributes to excessive diet soda intake in eating disorders: appetitive drive, weight concerns, or both?

Excessive diet soda intake is common in eating disorders. The present study examined factors contributing to excessive intake in a sample of individuals with lifetime eating disorders based on proposed DSM-5 criteria (n?=?240) and non-eating disorder controls (n?=?157). Individuals with eating disorders, particularly bulimia nervosa, consumed more diet soda than controls. Eating disorder symptoms that reflect increased appetitive drive or increased weight concerns were associated with increased diet soda intake. Increased weight concerns were associated with increased diet soda intake when levels of appetitive drive were high, but not when they were low. Results highlight the importance of monitoring diet soda intake in individuals with eating disorders and may have implications for the maintenance of dysregulated taste reward processing in bulimia nervosa.

Trajectories of eating and clinical symptoms over the course of a day hospital program for eating disorders.

Although it is well-established that day hospital programs for eating disorders significantly reduce clinical symptoms, the pre-test/post-test designs that were previously used do not provide information regarding the trajectory of symptoms during treatment. This study observed, on a weekly basis, the evolution of symptoms of 61 women suffering from eating disorders engaged in a day hospital program, and compared the trajectories of specific subgroups of patients. Results show that (a) the first half of the program was crucial for symptom changes; (b) although completers and non-completers presented similar initial improvement, their trajectories rapidly differentiated; and (c) poorer respondents initially reported more symptoms, showed a slower improvement, and never reached the non-clinical zone, whereas better-respondents reached the non-clinical cut-off point more rapidly.
