can anemia cause high blood sugar

Anemia itself does not directly cause high blood sugar, but certain types of anemia can affect the accuracy of blood sugar tests, including the A1C test. Here’s how:

• A1C Test Interference: Conditions like iron-deficiency anemia or hemolytic anemia can lead to falsely high or low A1C results. This is because the A1C test measures the percentage of glucose attached to hemoglobin, and anemia can alter the lifespan of red blood cells, skewing the results.
• Symptoms of Anemia: Fatigue and weakness from anemia might reduce physical activity, which can indirectly affect blood sugar control.

If you have anemia and are concerned about your blood sugar levels, consult your healthcare provider. They may recommend alternative tests, such as a fasting blood glucose test or continuous glucose monitoring, for more accurate results.
