What factor can heighten the risk of infection during surgery?

The presence of diabetes heightens the risk of infection during surgery due to several physiological factors associated with the condition. Individuals with diabetes often have impaired immune responses, which can make it difficult for the body to fight off infections. Additionally, diabetes can cause poor wound healing because elevated blood sugar levels can lead to a reduced supply of oxygen and nutrients to the tissues, thus slowing down the healing process and increasing susceptibility to postoperative infections.

Moreover, patients with diabetes may also have associated complications, such as neuropathy and vascular disease, which can further compromise skin integrity and the overall immune system response. These factors combined create a higher likelihood of surgical site infections in individuals with diabetes compared to those without the condition. Consequently, managing blood glucose levels and implementing additional infection control measures are crucial when a diabetic patient is undergoing surgery.
