ELI5: Why does diabetes increase your risk of just about everything?
gpt
Because it affects your blood flow, and proper blood flow is the key to maintaining your health aagainst viruses/infections and healing injuries. When your blood sugar becomes high, it is much harder for blood to travel around in your body. This is why the most delicate (eyes) and furthest away (feet + hands) parts are affected the most. For non-diabetics this is also true, but non-diabetics will rarely have a blood sugar high enough to cause damage. But diabetics cannot automatically control their sugar as well, and with years and years of very high sugar levels, damage slowly takes place.
