Anemia is a condition in which the number of red blood cells is too low or not working properly (the so-called Hemoglobin).

Malnutrition can lead to deficiencies in various nutrients of the Hemoglobin such as iron, folic acid, vitamin B12 and a vitamin A deficiency.

Chronic inflammations, parasite infections and congenital blood diseases can also cause anaemia. Severe anemia is associated with dizziness, weakness, and fatigue which affects development and learning performance.
