• When anaemia comes on slowly, the symptoms may include feeling tired, weakness, shortness of breath or a poor ability to exercise. Hence, The reduced flow of oxygen in the blood occurs in Anaemia

•  To diagnose anaemia, your doctor may ask you about your medical and family history, perform a physical exam, and run the following tests: Complete blood count (CBC) or Red cell distribution width (RDW).
•   A CBC is used to count the number of blood cells in a sample of your blood.
