A 1% drop in your A1c level can dramatically reduce your risk of complications.

The more tightly you control your blood sugar, the better. Small improvements can have a big impact on your health.
The A1c test measures your average blood sugar levels over a period of months. The result is given as a percentage score, from 6% to 12%. And an A1c level below 6% is normal for people who do not have diabetes. People with diabetes should aim for an A1c score of 7% or less.
|Peripheral vascular disease||22%|
|All diabetes-related deaths||25%|
You should have your A1c levels tested at least twice a year if your blood sugar is well controlled, and as often as every three months if you don't have your blood sugar under control.
Note: The percentage decreases in risk are not meant to be interpreted as cumulative. That is, a 2% decrease in A1c doesn't reduce the risk of complications by 70%.
