6. Blindness from Diabetes Is Extremely Common
One of the shocking facts that most people have no idea about involves vision loss from diabetes. Nearly 1/3 of those with diabetes over the age of 40 are going to lose their vision because of it.
When you have high blood sugar levels, it is more difficult for the blood to move throughout your body and that can result in nerve damage. This is especially true when it comes to the eyes because those nerves are particularly fragile. Many people lose their vision due to an illness called diabetic retinopathy.
