During the past decade, bariatric surgery has become an increasingly popular treatment option for the growing number of individuals with extreme obesity. For most individuals, the size and durability of the weight loss and improvements in co-morbidity and mortality have far surpassed those typically seen with behavioral modification and pharmacotherapy. A significant minority of patients, however, will experience suboptimal outcomes, including less than expected weight loss, premature weight regain, and frequent vomiting and/or gastric dumping. The reasons for these outcomes are not well understood, but likely involve both behavioral and physiologic processes. The present review highlights current knowledge on the changes in dietary intake and eating behavior that occur after bariatric surgery in terms of the potential threats these changes might pose to long-term postoperative success. The paper also identifies several strategies from the nonsurgical weight loss literature that might help optimize long-term weight maintenance after surgery.
在过去的十年中，减重手术已成为越来越多极度肥胖患者的一种流行治疗选择。对于大多数患者来说，减肥的幅度和持久性以及合并症和死亡率的改善远远超过了行为改变和药物治疗的效果。然而，少数患者会出现不理想的结果，包括减肥效果不如预期、体重过早反弹以及频繁呕吐和/或倾倒综合征。这些结果的原因尚不清楚，但可能涉及行为和生理过程。本文综述了减重手术后饮食摄入和饮食行为的变化，以及这些变化可能对长期术后成功带来的潜在威胁。本文还从非手术减肥文献中确定了几种策略，这些策略可能有助于优化手术后的长期体重维持。
