Definition: In Greek medicine, anaemesis refers to a state where blood cells do not proliferate effectively or are destroyed. Definition: - Anemia occurs when a body's red blood cell count (count of live red blood cells per milliliter) is too low compared to normal levels. The term 'anaemic' is derived from the Greek word 'anaematos', which means 'weak' or 'devoid of vitality'. - Anaemia is most commonly seen in conditions like bone marrow failure, such as chronic leukaemia, where there is a deficiency of red blood cells. - It can also manifest in conditions like sickle cell anemia, where the iron stores in the bone marrow are depleted and lead to red blood cells becoming small. - Anaemia can be treated with medications like iron supplements and transfusions that replenish the body's red blood cell supply.
