Emerging issues for the postbariatric surgical patient

Millions of individuals in the United States and around the world are overweight or obese. Bariatric surgery is now considered an evidenced-based choice for sustainable long-term weight loss and may reduce obesity-related comorbidities such as diabetes and obstructive sleep apnea. As bariatric surgical procedures increase, it can be expected that intensive care unit (ICU) admissions will increase as well. An emerging ICU population includes postbariatric patients either immediately after undergoing bariatric surgery or returning for subsequent surgical procedures. Massive weight loss following surgery leads to an excess of lax, overstretched skin, causing physical discomfort and psychosocial problems. It is important to understand the complex pathophysiological changes that occur in order to care for this growing population of patients. This review addresses the growing and evolving issues related to the complex nature of the postbariatric ICU patients.
