Adherence to Psychiatric Follow-up Predicts 1-Year BMI Loss in Gastric Bypass Surgery Patients.

OBJECTIVE: The objective of this study was to investigate the effects of adherence to postoperative recommended psychiatric follow-up on weight loss in morbid obesity patients with psychiatric disorders 1 year after gastric bypass. METHODS: Three hundred eighteen morbidly obese patients were retrospectively reviewed. They were divided into four groups according to preoperative psychiatric evaluations and adherence to psychiatric follow-up 1 year after their bypass surgery. The first group included patients who did not meet the referral criteria (NMRC). The second group consisted of patients who did not meet the psychiatric diagnostic criteria (NMDC). The third group was patients who met criteria for a psychiatric disorder and were nonadherent (NA) to psychiatric follow-up. The fourth group consisted of patients who met criteria for a psychiatric disorder and were adherent (A) to psychiatric follow-up. RESULTS: The A group exhibited higher % change in BMI than the NA and NMRC groups at 1 year after bypass surgery. Regression analyses to examine the effects of the grouping variable on % change in BMI were performed by controlling the effects of age, gender, educational level, and preoperative BMI. The regression coefficient for the grouping variable was 0.175 (p = .003) at the 6-month and 0.133 (p = .027) at the 1-year % change in BMI. CONCLUSION: Our preliminary data suggest that adherence to postoperative psychiatric follow-up is associated with greater postoperative weight loss. However, evidence from studies with a longer follow-up is required to justify this therapeutic approach.

Psychiatric aspects of bariatric surgery.

PURPOSE OF REVIEW: Bariatric surgery has been consistently shown to be effective in long-term marked weight loss and in bringing significant improvement to medical comorbidities such as metabolic syndrome. Empirical data suggest a high prevalence of psychiatric disorders among bariatric surgery candidates. In this review, we focus on the studies published recently with a high impact on our understanding of the role of psychiatry in bariatric surgery. RECENT FINDINGS: This article reviews the specific psychopathologies before surgery, changes in psychopathologies after surgery, suicide risk related to bariatric surgery, factors associated with weight loss, and recommendations for presurgical and postsurgical assessment and management. Research indicates a decrease in certain psychiatric symptoms after weight loss with bariatric surgery. However, the risk of suicide and unsuccessful weight loss in some bariatric surgery patients make monitoring following surgery as important as careful assessment and management before surgery. Specific considerations for youth and older populations and future potential research foci are discussed. SUMMARY: Recent publications suggest new directions for psychiatric evaluation and interventions for bariatric surgery patients. Future research on outcomes of specific populations, effectiveness of psychopharmacotherapy, and underlying pathophysiology are warranted for the advancement of treating bariatric surgery patients.
