Can anemia cause high A1C?

Our observation showed that conditions such as iron deficiency anemia can spuriously elevate A1C levels; consequently care should be taken before altering treatment regimen. Our observation also showed significantly higher A1C levels in anemic patients who had FPG between 100-126 mg/dl.

Why does anemia affect A1C?

A previous study conducted by Brooks et al. showed that iron deficiency anemia might alter the glycation rate of hemoglobin and cause elevations in A1c levels regardless of glycemia in patients without diabetes.

Does A1C decrease with anemia?

(21) found that among nondiabetic adults with iron-deficiency anemia, the A1C was 7.4 ± 0.3% before treatment and 6.2 ± 0.6% after treatment. Likewise, Tarim et al. (22) found that A1C in iron-deficient patients decreased from 7.6 ± 2.6 to 6.2 ± 1.4% after iron therapy (P < 0.05), despite similar glucose levels.

Can anemia affect blood sugar?

Iron deficiency (ID) and IDA can impair glucose homeostasis in animals and human and may negatively affect glycemic control and predispose to more complications in diabetic patients.

Can low B12 cause high A1C?

Certain types of untreated anemias: Anemia caused by a lack of iron, vitamin B12, or folate (vitamin B9) can falsely raise your A1C test results. Your body needs these vitamins and minerals to create new, healthy, red blood cells and replace older, dying ones.

Can anemia cause diabetes?

Anemia distorts regular method of diabetes diagnosis and questions its reliability. Summary: New research highlights how anemia — a common condition in the general population, especially in women — can lead to a false diagnosis of diabetes based on HbA1c, when a person’s blood sugar control is actually normal.

Can Vitamin B12 affect A1C?

If you’re taking iron or vitamin B12 supplements to treat those anemias, you’re encouraging your body to make new red blood cells. This can cause your A1C test to be falsely low. (Again, if you have an iron deficiency anemia and you’re NOT treating it, your A1C test will be falsely high.)

Does diabetes affect your iron levels?

Diabetes can contribute to anemia through reducing absorption of iron, gastrointestinal bleeding and through diabetic complications that cause anemia (1-3).

What can cause a false high A1C?

A falsely high A1C result can occur in people who are very low in iron; for example, those with iron-deficiency anemia link. Other causes of false A1C results include kidney failure or liver disease.

What can affect A1C levels?

What Can Affect Your A1C Result?

Kidney failure, liver disease, or severe anemia.
A less common type of hemoglobin that people of African, Mediterranean, or Southeast Asian descent and people with certain blood disorders (such as sickle cell anemia or thalassemia) may have.

What effect does anemia have on A1c?

Iron deficient anemia works the opposite from my understanding. It actually raises A1C. Therefore, iron treatment for this type of anemia will tend to lower A1C. There are other conditions the can affect A1C.

Is anemia and anemic the same thing?

Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. All parts of your body need oxygen. Anemia can starve your body of the oxygen it needs to survive. Some people refer to anemia as “low blood”. So yes basically Anemia is the same as “low blood”.

What is the difference between glucose and A1C?

Both can be used to diagnosed diabetes (a1c and fasting glucose) although a1c is a more stable parameter. An a1c is the average blood sugar over a 2-3 month period. A serum glucose is the blood sugar at the time the blood test is obtained. Both can be used to diagnosed diabetes (a1c and fasting glucose) although a1c is a more stable parameter.
