Why are diabetics at an increased risk for infections?

Individuals with diabetes are at an increased risk for infections primarily because high blood sugar levels can impair the immune system. When glucose levels in the bloodstream are consistently elevated, it can negatively affect various components of the immune system. For example, high blood sugar may hinder the function of white blood cells, which play a critical role in fighting off infections. Additionally, elevated glucose creates an environment that is conducive to the growth of certain pathogens, thereby increasing susceptibility to infections.

In diabetic patients, poor circulation and neuropathy can also contribute to reduced ability to detect and respond to infections, further complicating their health status. Adequate blood sugar management is essential for maintaining healthy immune function and reducing the risk of infections in individuals with diabetes.
