Parenteral Nutrition in the Postoperative Bariatric Patient
According to the American Society for Metabolic and Bariatric Surgery, obesity is considered a chronic, progressive disease resulting from multiple environmental and genetic factors. It is associated with serious health risks such as heart disease, stroke, type 2 diabetes, and even some forms of cancer— all which may lead to preventable, premature death. Bariatric surgery is one of the methods used to treat obesity and its associated comorbidities. While the safety of bariatric surgery has increased significantly, there are complications associated with these procedures that may necessitate the use of parenteral nutrition. This session will provide an overview of bariatric surgical options and potential associated complications.
Learning Outcomes:
At the conclusion of this session, attendees will be able to discuss bariatric surgical options and potential associated complications.
