What is AnaemiaLevel of haemoglobin which carries oxygen in the blood cells is insufficient or number of red blood cells fall below normal level.
Types of anaemiaThere are 4 main types of anaemia:
1. Not eating enough iron or loss of blood through heavy periods, internal bleeding via ulcers or cancer. Iron deficiency is the most common cause of anaemia, especially among adolescent girls and women during their reproductive years.
2. When red blood cells break down faster than they can be replaced such as in sickle-cell disease.
3. Leukaemia where production of red blood cells are impaired.
4. Deficiency of vitamin B12 which is needed for proper absorption of iron.
