From Dr Muccioli at Diabetes Daily:
Why are people with diabetes more vulnerable to infections and complications of infections? It has been shown that people with diabetes are at a higher risk for infections and related complications, and, in particular, for various bacterial infections. Although the reasons for this are not completely elucidated yet and are likely multifactorial, research has shown that high blood glucose levels can directly and negatively impact the immune system and that “…good control of blood sugar in diabetic patients is a desirable goal in the prevention of certain infections and to ensure maintenance of normal host defense mechanisms that determine resistance and response to infection.”As it relates to the COVID-19 outbreak, it follows that maintaining target blood glucose levels is an important preventative strategy for avoiding serious related complications, such as a secondary bacterial infection (i.e., pneumonia) and is likely an important determinant in the patient prognosis for anyone who becomes infected.
