Glucose is a form of sugar that your body uses as energy to perform its vital processes.
The measurement of glucose in your blood is a measurement of sugar in your blood and is typically performed either by a finger stick or using blood from a vein in your arm. This number tells us how well your body is metabolizing or using food as energy.
Yes; a glucose test and an A1C test. Glucose testing is performed after eight hours of fasting and measures how much glucose is present in the blood. An A1C test measures how long your blood sugar has been the way it is.
When there’s excess sugar, or glucose, in the body, it starts to stick to things. One of the things it sticks to is hemoglobin, which is the substance in red blood cells that helps carry oxygen throughout the body. When sugar sticks to it, it circulates through the system for a longer period of time than the glucose you eat does. So if your hemoglobin A1C is high, it means that your blood sugar has been high for quite some time. If it’s normal, it tells us that your blood sugar hasn’t been elevated for long.
In extreme conditions, your body isn’t processing glucose at all, which is typically called diabetes. In other circumstances, your body may not be processing glucose fully or completely, which is called pre-diabetes. Your body’s unwillingness to process sugar appropriately may be the result of a combination of things, including diet, medications or lack of physical activity.
