**4. Conclusion**

Although obesity leads to a pro-inflammatory state, it impairs the immune system and is a risk factor for several infections. Moreover, in surgical site infection, there are local factors related to obesity that must be taken into account: a large adipose panicle with poor oxygenation, a reduced operative field, difficulties in technique, and increased operative time. Therefore, obesity is a proven risk factor for surgical site infection in plenty of surgeries. However, there are some actions that we could take to reduce this risk: performing minimal invasive surgery, ensuring adequate surgical technique, prescribing adequate antibiotic doses, and recommending weight loss.
