Morbid obesity is associated with several significant comorbidities, including obstructive sleep apnea, hypertension, type 2 diabetes mellitus, and metabolic syndrome—with resolution rates of 80% or more after effective intervention. Over 200 comorbidities are linked to obesity, including several types of cancer. With nearly 40% of adults and one-third of children in the United States classified as obese or overweight, ongoing research continues into pharmacotherapy options and the endocrine factors influencing weight regulation. Newer medications, such as glucagon-like peptide-1 (GLP-1) agonists and combination GLP-1/gastric inhibitory peptide/glucose-dependent insulinotropic peptide (GIP) (GLP-1/GIP) agonists, have shown promise in achieving greater than 20% total body weight loss in patients with morbid obesity.[1] However, concerns about cost, adverse events, and long-term safety remain. Despite these advances, weight loss surgery remains the gold standard for resolving comorbidities in those who are morbidly obese, offering 30% to 40% total body weight loss. Older antiobesity medications (AOMs), such as phentermine, topiramate, buprenorphine, and naltrexone, contribute to 5% to 10% weight reduction, with newer AOMs filling the gap for those in between. Laparoscopic sleeve gastrectomy, a restrictive weight loss procedure, is the most commonly performed bariatric surgery in the United States, accounting for over two-thirds of all bariatric surgeries, with over 160,000 procedures conducted in 2022. The Roux-en-Y gastric bypass is the second most common, with gastric banding and duodenal switch procedures being much rarer.[2] Bariatric surgery can effectively reverse comorbidities such as diabetes, obstructive sleep apnea, metabolic syndrome, and pseudotumor cerebrii. Though generally safe when performed by experienced surgeons, complications can arise immediately postoperatively and even years later. These complications can range from subtle, gradually progressing symptoms to more acute conditions requiring urgent intervention. Common complications include deep vein thrombosis, bleeding, hiatal hernia, nutritional deficiencies, anastomotic leaks or strictures, gastric and marginal ulcers, and dumping syndrome. Bariatric individuals must have timely access to follow-up care to address any potential complications as they arise.[3][4]

Effective management of bariatric surgery complications requires strong collaboration and interprofessional communication among advanced clinicians, nurses, pharmacists, and other healthcare professionals. Clinicians, particularly bariatric surgeons, lead the team by diagnosing and addressing surgical complications such as anastomotic leaks or internal hernias, while advanced clinicians, including nurse practitioners and physician assistants, provide continuous patient assessments and support during postoperative care. Nurses are crucial in monitoring vital signs, managing pain, and detecting early signs of complications such as infection or gastrointestinal distress. Pharmacists contribute by ensuring appropriate medication management, particularly pain control, antibiotics, and nutritional supplements, to prevent deficiencies that can arise post-surgery. Interprofessional communication is key to enhancing patient outcomes and ensuring the team is aligned regarding strategies. Effective care coordination between these roles ensures that nutritional needs are met, psychological support is available, and any complications are addressed promptly. For instance, the nutritionist works with the surgical team to monitor the patient's diet and nutritional status. At the same time, the psychiatrist or psychologist may address emotional challenges or eating disorders that impact recovery. Coordinated efforts help mitigate risks, improve patient safety, and improve outcomes, as the team can provide comprehensive care tailored to each patient’s needs. This holistic, patient-centered approach fosters a supportive environment for patients and ensures timely interventions, ultimately improving team performance and optimizing the success of bariatric surgery.

Interprofessional collaboration is important for optimal results following bariatric surgery. An accurate assessment and counseling to focus on eating habits and glycemic control is crucial before and following bariatric surgery. Nutritional expert-led support groups increase long-term weight loss and help optimize nutrition. Involving a diverse interdisciplinary team in bariatric programs improves communication, and identification of issues, and allows more timely access to clinical care. Treatment teams optimize outcomes and improve recidivism in a condition that can result in tremendous morbidity and mortality.[38][39]

Nutritional parameters should be monitored regularly after bariatric surgery, including B vitamins, iron and trace elements. General labwork should be followed annually, including liver function tests, complete blood count, basic metabolic panel, and lipid panel.[40]
