Anemia is a common disorder in the elderly and is associated with increased morbidity and mortality. In elderly subjects, in whom anemia is highly prevalent, there are several aspects, such as a hemoglobin at a level which should concern us limit, or identifying its causes, that are not easy to establish. This review focuses on knowing what is considered to be normal hemoglobin levels in adults and the common causes and potential consequences of anemia in elderly patients. It provides a diagnostic algorithm and an approach to treatment that addresses new treatments such as parenteral iron drugs and erythropoiesis-stimulating agents.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
