ABSTRACT Research has demonstrated that laparoscopic Roux-en-Y gastric bypass patients with a lifetime history of a mood disorder have a lower percentage of excess weight loss (%EWL) compared with patients without this lifetime history. No studies have examined the effect of psychiatric history on postoperative outcomes among laparoscopic sleeve gastrectomy (LSG) patients. The objectives of the present study were to determine whether mood disorders relate to the first year of weight loss for patients undergoing LSG at an academic medical center.
A total of 104 patients (78.6% white and 71.2% women), with a median body mass index of 60.35 kg/m(2) (range 31.37-129.14) underwent LSG. The patients were prospectively followed up at 1, 3, 6, 9, and 12 months. The semistructured preoperative psychiatric evaluations demonstrated that 43.1% had a current, and 62.5% a lifetime, diagnosis of a mood disorder.
LSG patients with current mood disorders had a significantly lower %EWL than patients without a psychiatric diagnosis at the 1-, 3-, 6-, and 9-month follow-up visits. LSG patients with a lifetime history of a mood disorder had a significantly lower %EWL than patients without psychiatric diagnosis at the 1-, 9-, and 12-month follow-up examinations. However, after removing patients with bipolar disorder from the analyses, no significant differences were found in the %EWL between patients with and without a lifetime history of depressive disorders.
Consistent with the laparoscopic Roux-en-Y gastric bypass findings, a lifetime history of mood disorders appears to be associated with significantly less weight loss in LSG patients. These findings highlight the importance of the psychiatric assessment in bariatric patients. Additionally, patients with a current or lifetime history of mood disorders might need additional pre- and postoperative care to improve their outcomes.

    ABSTRACT: Bipolar disorder (BD) is associated with obesity, overweight, and abdominal obesity, and BD individuals with obesity have a greater illness burden. Factors related to BD, its treatment, and the individual may all contribute to BD's association with obesity. Management strategies for the obese BD patient include use of medications with better metabolic profiles, lifestyle interventions, and adjunctive pharmacotherapy for weight loss. Obesity-related psychiatric and medical comorbidities should also be assessed and managed. Bariatric surgery may be an option for carefully selected patients. Greater research into the theoretical underpinnings and clinical management of the BD-obesity connection is needed.

    ABSTRACT: 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.

    ABSTRACT: Persons with bipolar disorder (BD) have an increased risk of obesity and associated diseases. Success of current behavioral treatment for obesity in patients with BD is inadequate. Existing literature on bariatric surgery outcomes in populations with BD were reviewed, and needed areas of research were identified. Knowledge about bariatric surgery outcomes among patients with BD is limited. Available evidence indicates that bariatric surgery is a uniquely effective intervention for achieving and sustaining significant weight loss and improving metabolic parameters. Notwithstanding the benefits of bariatric surgery in nonpsychiatric samples, individuals with BD (and other serious and persistent mental illnesses) have decreased access to this intervention. Areas of needed research include: (1) current practice patterns; (2) metabolic course after bariatric surgery; (3) psychiatric course after bariatric surgery; and (4) mechanisms of psychiatric effect. The considerable hazards posed by obesity in BD, as measured by illness complexity and premature mortality, provide the basis for hypothesizing that bariatric surgery may prevent and improve morbidity in this patient population. In addition to physical health benefits, bariatric surgery may exert a robust and favorable effect on the course and outcome of BD and reduce obesity-associated morbidity, the most frequent cause of premature mortality in this patient population.
