Can anemia cause an increase in HbA1c level?

Question

Hi doctor,

I am diagnosed with HbA1c 7.5 % and have not done PPBS and RBS. My Hb is 9 gm/dL due to premenopause with heavy menstrual bleeding. Previously my Hb was 8 gm/dL. Now improved with an iron tablet. Am I diabetic, or should I go early for medication, or is lifestyle change enough?

Answer 1

Hi,

Welcome to icliniq.com.

I understand your concern. I need further details. Do you have any symptoms? Are any other medical conditions other than low Hb (hemoglobin)? Per the definition of diabetes, HbA1c (glycated hemoglobin) of 6.5 % or more is diabetic. Lifestyle modification and proper diet is the cornerstone of diabetes management. However, at this stage, you also need medications. It is helpful to reduce your weight as well. Do not worry; you can live a normal life with treatment, diet, and exercise. Please visit a nearby diabetologist. If you wish to consult with me, please schedule an online consultation on this platform. I hope it helps. Kind regards.

Hi,

Welcome back to icliniq.com.

I understand your concern. The reason why I had asked if you have any symptoms. In anemic people, there is a false elevation of HbA1c due to the rapid turnover of RBCs (red blood cells). Although glycated fructosamine can be done, which is not affected by the Hb, I suggest you get fasting sugar and PPBS (post-prandial blood sugar) done once, as they are much more straightforward and easily available. Although it is good to know the anemia is improving, getting treatment for irregular or heavy periods is equally important. You can visit your gynecologist for the same. I hope it helps. Kind regards.
