A1C Average Blood Sugar Chart: Normal, Prediabetes, and Diabetes Ranges

Image
The A1C test, or hemoglobin A1C or HbA1C, is critical in diabetes care. It measures the average blood sugar (Glucose) levels over the past two to three months by assessing the percentage of hemoglobin—a protein in red blood cells—that has glucose attached to it.    Unlike daily finger-prick tests that provide a snapshot of blood sugar at a single moment, the A1C test offers a broader view of glycemic control.    For individuals with diabetes, this long-term perspective helps healthcare providers evaluate how well their treatment plan works and adjust medications, diet, or lifestyle as needed.     Consistently high blood sugar levels can silently damage blood vessels, nerves, and organs over time, increasing the risk of complications such as heart disease, kidney failure, vision loss, and neuropathy.    Regular monitoring, whether through daily glucose checks or periodic A1C tests, empowers individuals to catch trends early and take action....

    What is Blood Sugar?   Blood sugar, also called glucose, is the sugar in your bloodstream that comes from your food.    Think of it like fuel for a car—your body uses this sugar to power everything you do, from running to solving math problems.    It’s vital for your brain, which relies on glucose, to stay sharp and focused.    However, just like too much or too little gas can harm a car, having blood sugar levels that are too high or too low can cause serious health problems.    For example, consistently high levels might lead to diabetes. In contrast, low levels can make you feel dizzy, tired, or even faint.   This article will help you understand normal blood sugar levels by breaking down a simple chart.    You’ll learn the healthy ranges for different times of day—like before meals or after exercise—and why these numbers matter.    Tracking your blood sugar isn’t just for people with diabetes; it’s a...
