Obesity-related immune responses and their impact on surgical outcomes

The obesity epidemic represents a critical disease burden with broad clinical consequences. At the same time, obesity has been linked to inferior surgical outcomes and considered a contraindication for some elective surgical procedures. A growing body of mechanistic evidence has accumulated linking obesity to changes of metabolism and immune responses. This concept provides an integrated inflammatory network based on the perception of obesity as a state of chronic low-grade inflammation. With a more detailed understanding of this dynamic network and mechanistic insights, novel treatment and management strategies may be developed with the goal to optimize surgical outcomes in obese patients.
