Best Practices in the Management of Overweight and Obesity.

Obesity is a chronic disease caused by dysregulated energy homeostasis pathways that encourage the accumulation of adiposity, which in turn results in the development or exacerbation of weight-related comorbidities. Treatment of obesity relies on a foundation of lifestyle modification; weight loss pharmacotherapy, bariatric surgery and devices are additional tools to help patients achieve their health goals. Appropriate management of patients with obesity provides multiple metabolic benefits beyond weight loss.

Surgical and Nonsurgical Weight Loss for Patients with Obstructive Sleep Apnea.

A strong association exists between excess weight and obstructive sleep apnea (OSA), and most patients with OSA have elevated body mass index. Weight loss is an essential part of treatment for patients with OSA and overweight or obesity. Lifestyle interventions are cornerstones of weight management. However, most patients have difficulty achieving and maintaining clinically significant weight loss with lifestyle interventions alone. Health care providers who treat patients with OSA should be familiar with advanced treatment options for overweight and obesity including antiobesity medications, bariatric surgery, and devices. The future of weight management is a customized, multidisciplinary approach for each patient.

Obesity: When to consider surgery.

Bariatric surgery is underutilized despite an obesity epidemic. Here, 3 patients pursue a surgical option when they can't reach their target weight and optimal health by nonsurgical means.

Devices and Endoscopic Bariatric Therapies for Obesity.

PURPOSE OF REVIEW: In this review, we describe the FDA-approved and investigational devices and endoscopic bariatric therapies for the treatment of obesity. We focus on literature published in the past few years and present mechanisms of action as well as efficacy and safety data. RECENT FINDINGS: Devices and endoscopic procedures are emerging options to fill the significant treatment gap in the management of obesity. Not only are these devices and procedures minimally invasive and reversible, but they are potentially more effective than antiobesity medications, often safer for poor surgical candidates and possibly less expensive than bariatric surgery. As many patients require a variety of management strategies (medications, devices, procedures, and/or surgery) in addition to lifestyle modifications to achieve clinically significant weight loss, the future of obesity treatment involves a multidisciplinary approach. Combinations of advanced treatment strategies can lead to additive or synergistic weight loss. This is an area that requires further investigation.

Practical Use of Pharmacotherapy for Obesity.

Obesity management requires a multidisciplinary approach, as there are many factors that contribute to the development of obesity, as well as the preservation of excess weight once it has been gained. Diet, exercise, and behavior modification are key components of treatment. In addition to lifestyle changes, weight gain secondary to medications is an important modifiable risk factor. Even after appropriate lifestyle modification, and medication adjustments (where possible) to avoid agents that can contribute to weight gain, many patients are still unable to achieve clinically meaningful weight loss. Pharmacotherapy for obesity management can fill an important role for these patients. This article will review medications that can lead to weight gain and potential alternatives, currently approved anti-obesity medications and best practices to individualize the selection process, and the use of testosterone in men with hypogonadism and obesity.

An update on naltrexone/bupropion extended-release in the treatment of obesity.

INTRODUCTION: As the prevalence of obesity continues to increase, the need for effective long-term treatment strategies for overweight and obesity is critical. Pharmacology fills a large treatment gap between behavioral therapy, which is insufficient for the majority of patients, and devices and surgery, which are available to only a subset of patients. Naltrexone HCl and bupropion HCl Extended-Release (naltrexone XR/bupropion XR) was approved by the Food and Drug Administration for chronic weight management in 2014. Areas covered: This review illustrates the efficacy and safety of naltrexone XR/bupropion XR by examining data from clinical trials. It also provides an overview of the market and presents the pharmacodynamics and pharmacokinetics of naltrexone and bupropion. Expert opinion: The efficacy and safety profile of naltrexone XR/bupropion XR makes it a viable option for many patients who could benefit from its distinctive mechanism. The medication was shown to produce additive weight loss when combined with an intensive behavioral modification program and it may improve food cravings and eating behaviors. Compared to the other three antiobesity medications approved since 2012, naltrexone XR/bupropion XR is neither a controlled substance nor an injectable agent.

Pharmacologic Approaches to Weight Management: Recent Gains and Shortfalls in Combating Obesity.

Obesity is a growing epidemic in the USA with over one third of adults presently classified as obese. Obesity-related comorbidities include many leading causes of preventable death such as heart disease, stroke, type 2 diabetes, and certain types of cancer. Modest weight loss of 5-10 % of body weight is sufficient to produce clinically relevant improvements in cardiovascular disease risk factors among patients with overweight and obesity. Until recently, there were limited pharmacologic options approved by the Food and Drug Administration to treat obesity. Phentermine/topiramate ER and lorcaserin were approved in 2012, and naltrexone SR/bupropion SR and liraglutide 3.0 mg were approved in 2014. This article reviews recent literature in the field of Obesity Medicine and highlights important findings from clinical trials. Future directions in the pharmacologic management of obesity are presented along with new diabetes medications that promote weight loss and reduce cardiovascular mortality.
