The aim of present study was to study the levels and analyze the variation in glycosylated hemoglobin (HbA1c) levels in Iron Deficiency Anemia (IDA).This study was conducted on 50 cases who were diagnosed to be having iron deficiency anemia and 50 age matched healthy controls which are not having any form of anemia. The levels of HbA1cwas significant increased in cases ofiron deficiency anemia as compared to those in the healthycontrols. There were no differences in the random glucose levels between the anemic and healthy subjects. It is not only the blood sugar levels that affects HbA1c levels but it also may be affected by other factors such as hemoglobinopathies and anemia among which most common in India is iron deficiency anemia. Hence, it very vital to be have an estimate of iron levels in the blood so as to be able to take therapeutic decision to treat diabetes based on HbA1c levels. Therefore, it is always advisable to correct any iron deficiency before any diagnostic or therapeutic decision is made.
