How Can I Lower my A1c Fast?

There is no way to lower your A1c fast. It took 2.5 to 3 months to get your A1c to what it is now, and it will take just that long of improved nutrition, physical activity, and medication to get it lower.


hemoglobin A1C blood test

A1c, also known as hemoglobin A1c is the most common subtype of hemoglobin molecule in our blood. (There is also hemoglobin A2, A1a, and A1b, for example.) The blood test of glycosylated hemoglobin A1c measures what percent of your hemoglobin A1c molecules have sugar, or glucose, attached to them.


Hemoglobin molecules are found in your red blood cells. Red blood cells have a life span of 2.5 to 3 months. Once a red blood cell dies, the contents, including hemoglobin molecules are degraded. This includes the glycosylated hemoglobin molecules--the ones that have glucose attached. It takes a full 2.5 to 3 months to turn over your hemoglobin molecules.


You might be wondering if the glucose that is attached to your hemoglobin A1c can just be removed from the hemoglobin A1c. Unfortunately, it can't! It will take 2.5 to 3 months for the glycosylated hemoglobin levels to reflect your efforts to reduce it.


Typically, medical providers do not check glycosylated hemoglobin A1c any more frequently than every 3 months. This is the perfect interval, because that is just as long as it will take for your nutrition, physical activity, and medication changes to cause a change in your blood test. If you start those changes right away, you won't have to worry about getting the change done fast, because the fastest way to do it will take 2.5 to 3 months.
