What is Anemia ?
A condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiologic needs, which vary by age, sex, altitude, smoking, and pregnancy status.

In it is severe form, it is associated with fatigue, weakness, dizziness and drowsiness. Pregnant women and children are particularly vulnerable.

- Aplastic anemia, a condition that can be inherited or acquired
- G6PD deficiency (is a genetic disorder that most often affects males. It happens when the body does not have enough of
