Type II diabetes in particular causes a certain amount of immune suppression.

Further complicating this is that it also causes poor circulation and neuropathy (reduced nerve sensation) in extremities like hands and feet so that diabetics often don’t feel small wounds and may not clean and dress them properly because they’re unaware they have them, so a small problem often isn’t noticed until it’s already become a big problem.
