I did a boold test and my hemoglobin ac1 is at 5.6 is that bad and how fast can it get to 5.7 pre diabetes?

Great: Hemoglobin a1c of 5.6 is great. That is normal. If you are a diabetic you are doing awesome, if you aren't you still aren't

5.6 is "normal": An a1c of 5.6 is considered normal. This test measures the "sugar coating" of your red blood cells. A value of 7.0 or higher means the average sugars are >140 and can cause damage to nerves, blood vessels, kidneys, etc. To keep the a1c down, focus on diet and exercise. Regular resistance exercise (weights, resistance bands, etc) have been shown to decrease sugars quite a bit!
