ELI5. Why does recovery from an injury or cut, takes longer time for a person with high blood sugar than a normal person

Sugar is a bunch of tiny crystals. Sharp. This means they can be pretty scratchy. Too much of it can actually scratch up your arteries and veins a bit
This is what people mean when they say sugar is “inflammatory”; Your veins swell up a little bit in response to the irritation; Think like a bruise.
This swelling of the veins can cause poor blood flow because the squeeze is tighter, which slows the delivery of nutrients that would help exterior wounds.
Ontop of that, sugar is shaped similarly enough to vitamin C, that your white blood cells can actually mistake sugar for it. As a result, some of your white blood cells will actually not get any vitamin C.
Since vitamin C helps your cells with fighting infections (pathogens), and sugar doesn’t, it can slow things down even more
