In which circumstance is there a greater risk of complications during surgery?

Obese patients are at higher risk of wound complications due to several factors associated with obesity. The presence of excess body fat can lead to a decreased blood supply in adipose tissue, which impairs healing after surgery. Additionally, obesity is associated with a higher likelihood of developing infections, both due to the nature of surgical wounds and the body's inflammatory response to injury.

Obese individuals may also have other comorbidities, such as diabetes and cardiovascular issues, which can further increase the risk of complications during and after surgery. These factors create a challenging environment for surgical recovery, making it critical for healthcare professionals to closely monitor and manage obese patients undergoing surgical procedures.

In comparison, although diabetes and smoking also present risks during surgery, the specific complications associated with obesity, particularly concerning wound healing and infection, are particularly pronounced. Younger patients typically do not face the same level of risk as older populations, especially in terms of wound complications.
