What is Blood Sugar and A1C?

Blood sugar is the main sugar found in the blood. We get the glucose from the food we eat. Blood sugar is an important source of energy for the body’s organs, muscles, and nervous system. The insulin produced by the pancreas helps to regulate the glucose in the bloodstream so that it can be stored and processed by the body correctly.

Hemoglobin A1C, also known as just A1C, is the average levels of blood sugar over a 3 month period. Hemoglobin is the part of the red blood cells that carries oxygen to the cells. Glucose attaches/binds with the hemoglobin and A1C tests are based on this attachment and show the heightened levels of glucose in the blood. This means high levels of glucose are attached to hemoglobin and in your bloodstream.

Normal people have an A1C of 5.7% or less.
Prediabetic people have an A1C of 5.7-6.4%.
Diabetic people have an A1C of 6.5% or more.

Check out this chart to get an idea of what your blood sugar should look like whether or not you have diabetes.
It’s also A good indicator to see whether or not you may have diabetes.

Glucose is fuel for your body when it is at normal levels. High sugar levels in the bloodstream erode the ability of cells in the pancreas to make insulin which can permanently damage the pancreas. This could also lead to the hardening of blood vessels.

Getting the A1C test will help your doctor determine if you have prediabetes or full blown diabetes and then counsel you on any lifestyle changes and monitor your condition. If you catch it in the prediabetes stage, you have the chance to reverse it and keep yourself away from diabetes.

I was told for two years that I was on the verge of getting diabetes. My doctor gave me multiple chances and I still didn’t listen. Now I have to work extra hard to lose the weight and fix my lifestyle. I don’t think I can fully reverse my diabetes now, but I can manage it to the best of my ability. It’s just a lot of work now.

I created a printable daily diabetic log where you can keep track of the medication you took, your blood sugar for the day, any workout you had, and the food you ate for the day. Click here to download the log and keep track of your day. I plan to come out with more printables to help keep you accountable with your diabetes, so stay tuned!
