Know The Link Between Hemoglobin And Diabetes

By on November 14, 2014

Hemoglobin is a protein molecule in red blood cells, responsible to carry oxygen from lungs to all other parts of the body. Almost all the oxygen in your blood is carried through hemoglobin, so it is vitally important.

Now we will discuss about the link between hemoglobin and diabetes. When we take the food, our body extracts glucose or sugar from those foods and uses it for energy.

It ultimately ends up into the bloodstream so that it can be transferred to all the parts of the body.

During this process, sometimes some sugars that enter into the bloodstream may attach to the hemoglobin on the red blood cells and stays there for almost three months.

Hemoglobin And DiabetesSo, when the level of the sugar increases in your red blood cells, which is nothing but the many people with diabetes have.

What happens when higher amount of sugar attaches to the bloodstream?

If a person with diabetes consumes higher levels of sugars, then it can increase the risk of several health problems, such as problems with:

  • Blood vessels
  • Eyes
  • Feet
  • Heart
  • Kidneys
  • Nerves

People with diabetes are usually prescribed with daily glucose test, which is critically important for diabetes management.

But these tests will only give a snapshot of the levels of glucose in the bloodstream at the time of the test. When you perform the test again after one hour, the results may vary.

So, for accuracy there is a test named Hemoglobin A1c. It gives longer view of glucose levels through measuring the amount of glucose that is attached to the hemoglobin over the life of red blood cells, which is about three months.


The test is considered as a gold standard test recommended by American Diabetes Association to understand long-term levels of glucose in the blood. The test result is not accurate for any given day, but it gives the doctor a good idea of how effective your blood sugar control has been over time.

Usually A1C level is below 5.7 percent. 6.5 percent or above indicates that the person is diabetic. 5.7 to 6.4 percent indicates that the persona is at pre-diabetes levels. To monitor your overall glucose control, diabetics should have an A1C at least twice a year.

According to the A1C results, if you are in the early stages of the disease, small lifestyle changes can help to make a big difference and even reverse diabetes test results. Losing the weight and exercising can make a lot of difference in your diabetes levels.
