**1. Introduction**

Anemia is rising in importance as a biomedical research priority and a public health issue in the old age group. World health organization (WHO) has defined anemia as hemoglobin concentration (Hb %) below 12 g/dL in women and below 13 g/dL in men [1]. Hb declines slightly with more advancing age with frequency of anemia being more pronounced in men. The geriatric anemia is related with mortality and inferior health associated quality of life [2, 3]. This is important area to be explored as there is little literature that explains the association of anemia with old age and lesser research has led anemia to go undiagnosed and untreated. In the shade of absent obvious ailment, complaints of generalized weakness left ignored [4–9]. The incidence of anemia increases comorbidities resulting in increased frequency of hospitalizations hence leading on to adverse impact on survival [10, 11]. So a better outlook is needed to define the optimal Hb levels and to diagnose out the cause of anemia in old age group [12, 13].
