Iron deficiency anaemiaIron deficiency anaemia is a condition in which the body has too little iron in the bloodstream. This form of anaemia is more common in adolescents and in women before menopause. Blood loss from heavy periods, internal bleeding from the gastrointestinal tract, or donating too much blood can all contribute to this disease. Other causes can be from poor dietary habits or from chronic intestinal diseases.

Folic Acid Deficiency AnaemiaThis form of anaemia is characterised by a lack of folic acid, one of the B group of vitamins, in the bloodstream. This is usually caused by an inadequate intake of folic acid, usually found in vegetables or by the overcooking of the vegetables. Alcoholism can also be a contributing factor in this form of anaemia. During pregnancy when the folic acid is used more or in infancy, this disease can also manifest itself. It can also be caused as a side effect of other blood disorders.

Pernicious anaemiaPernicious anaemia usually affects people between the ages of 50 and 60 and is a result of a lack of vitamin B12. The disease can be hereditary but some forms of the condition can be autoimmune diseases. People who have any autoimmune diseases are more likely to contract pernicious anaemia.
