Obesity is a chronic, multifactorial disease characterized by excess adiposity that adversely affects metabolic, cardiovascular, respiratory, hepatic, and psychosocial health. Elevated body mass index and central adiposity increase the risk of type 2 diabetes mellitus, hypertension, dyslipidemia, obstructive sleep apnea, metabolic liver disease, osteoarthritis, and selected cancers. Disease burden extends beyond medical comorbidities to include reduced quality of life, impaired function, and increased health care utilization. Sustained weight loss remains difficult to achieve with lifestyle interventions alone for many patients, whereas evidence supports advanced pharmacologic therapies and metabolic surgery as effective options for risk reduction and remission of comorbidities in appropriately selected individuals. Emphasis on coordinated, patient-centered care is essential to optimize outcomes across the continuum of obesity management. This activity equips participants to evaluate obesity severity, assess comorbidity burden, and apply contemporary eligibility criteria for metabolic surgery and antiobesity pharmacotherapy. Core competencies include preoperative risk stratification; counseling regarding benefits, limitations, and complications; recognition of postoperative complications such as bleeding, leak, internal hernia, obstruction, and postbariatric hypoglycemia; and implementation of long-term surveillance for nutritional deficiencies. Instruction highlights structured follow-up to address weight regain, maladaptive eating behaviors, and mental health comorbidities. Collaboration within an interprofessional team—including surgeons, primary care clinicians, nurses, dietitians, behavioral health clinicians, pharmacists, and rehabilitation specialists—enhances outcomes through coordinated decision-making, standardized protocols, early detection of complications, and consistent patient education that supports sustained metabolic improvement. Objectives: Determine candidacy for antiobesity medications or metabolic surgery based on clinical criteria, comorbidity burden, and patient goals. Develop longitudinal monitoring strategies that address weight trajectory, metabolic health, nutritional adequacy, and behavioral adherence.

Obesity is defined as a body mass index (BMI) of 30 kg/m², and severe obesity is defined as a BMI of greater than 40 kg/m². The prevalence of obesity is approximately 40% in the United States, and is more common in those between the ages of 40 and 59. The prevalence of severe obesity is 9.4% and is higher among women.[1] Global obesity prevalence is estimated at 37%, accounting for 2.8 million deaths per year, and has doubled since 1990.[2] The societal burden of obesity is multifaceted, with a profound impact on the economy and the overall well-being of the population. Obesity is associated with conditions such as cardiovascular disease, type 2 diabetes mellitus, metabolic dysfunction, dyslipidemia, obstructive sleep apnea, liver disease, and cancer. Obesity is one of the leading causes of preventable death, according to global obesity statistics (Global Obesity).[3] Inflammation plays a significant role in the comorbid conditions and physical manifestations of obesity. Chronic inflammation is, in part, mediated by adipose cytokines such as interleukin-6, leading to decreased wound healing and disrupted innervation through impaired signal transduction. Interleukin-6 and inflammation also affect neurotransmitters, cerebellar signaling, and endothelial cell signaling to the brain. Obesity is multifactorial and is caused by lifestyle factors, medications, comorbidities, heritable conditions, and psychosocial issues. Results from meta-analyses have shown that caloric restriction alone usually does not lead to sustained weight loss. Furthermore, pharmacologic advances in weight management do not offer the same degree of long-term success as surgical intervention. The class of glucagon-like peptide-1 receptor agonists offers improved weight loss compared with other medical therapies, but bariatric surgery consistently yields superior long-term weight loss and more successful remission of obesity-related comorbidities. Bariatric surgery is most effective for those with a BMI greater than 40 kg/m². Coupled with counseling and education focused on lifestyle modification within multimodal bariatric programs, bariatric surgery offers a long-term remedy for obesity-related systemic metabolic dysfunction.[4][5][6][7][8]

Coupled with counseling and education focused on lifestyle modification within multimodal bariatric programs, bariatric surgery offers a long-term remedy for obesity-related systemic metabolic dysfunction.[4][5][6][7][8] Persons with obesity are risk-stratified using BMI, waist circumference, and assessment of comorbidities. Counseling and postoperative management are critical components of comprehensive care for patients with obesity. Goals of preoperative counseling include promoting sustained behavior modification and conducting a thorough risk-benefit analysis to support patient-centered, shared decision-making. Another essential component of preoperative counseling is educating patients about the short- and long-term risks of bariatric surgery, including steps to mitigate and recognize potential complications. Nutritional guidelines before and after bariatric surgery are another critical subject covered both preoperatively and postoperatively.[9]

Obesity is most effectively treated within an interdisciplinary setting by subspecialty-trained professionals. A comprehensive team includes surgeons, anesthetists, obesity medicine specialists, primary care clinicians, endocrinologists, gastroenterologists, psychiatrists, psychologists, nutritionists, nurses, and physiotherapists. Achieving the best outcomes requires collaboration and communication, and the application of the medical pillars of beneficence, nonmaleficence, justice, and autonomy. Bariatric medicine is patient-centered, and safety is always at the forefront. The team that employs specialized training and operates under these principles has achieved improved outcomes.
