It's clear that uncontrolled glucose control can exacerbate the risk of infections in type 2's and that maintaining excellent control reduces infection risk but the reality is that many (not all) type 2's have co-morbidities which increase infection risk anyway. Conditions like high blood pressure, inflammatory conditions, obesity related issues, other auto-immune conditions for example all increase vulnerability to bacterial, viral and fungal infections.
I understand Type 1's are said to have higher infection risk because the auto immune nature of their condition impacts on the immune system generally even when it's reasonably well controlled. And that's no mean feat it seems!
I'm faced with a double whammy with type 2 diabetes and cancer of the immune system where infection is particularly hazardous to me. I have a bad cold at present and cannot automatically rely on my antibodies kicking in to deal with it. That's when infection feels really scary! 😱
