Diabetes is a horrific disease that affects millions of people in ways that the average, healthy human cannot understand. While you can live well into your elderly years with diabetes, there are certain rituals that a diabetic sticks to day in and day out that make it possible to live well into those years. Those rituals may involve glucose blood tests, better dietary habits, and even medication. It's not uncommon to believe that in the same way someone with the flu feels like their whole body is affected, someone with diabetes will also have other complications that affect various parts of their body - like their eyes. Diabetes, if not treated properly, can wreak havoc on a person's body and the eyes are definitely not excluded from it.
