Anaemia is classified into seven (7) major types in the work of Natasha & Yasmin (2013) which are iron deficiency anaemia, thalassaemia, aplastic anaemia, haemolytic anaemia, sickle cell anaemia, pernicious anaemia and fanconi anaemia.
Among the seven types of anaemia, only two - iron deficiency anaemia and pernicious anaemia are directly attributed to nutritional disorder (Sinha, et al, 1998) which is the scope of this work.
Iron Deficiency Anaemia
This is the most common form of anaemia. It is usually due to chronic blood loss caused by excessive menstruation. Increased demands for iron, such as foetal growth in pregnancy, and children undergoing rapid growth spurts in infancy and adolescence, can also cause iron deficiency anaemia.
Pernicious Anaemia
Pernicious anaemia is a condition in which the body can't make enough healthy red blood cells because it doesn't have enough vitamin B12 (a nutrient found in certain foods). People who have pernicious anaemia can't absorb enough vitamin B12 due to a lack of intrinsic factor (a protein made in the stomach). However, other conditions and factors can also cause vitamin B12 deficiency.
