- Iron deficiency is common in many developing countries due to inadequate dietary intake from childhood.
Characteristics of Hypochromic Anemia
- In hypochromic anemia, red blood cells appear small and pale due to the insufficient production of hemoglobin.
Iron Loss and Hemorrhage
- Excess loss of iron can occur as a result of hemorrhage, leading to iron deficiency anemia.
- Iron deficiency anemia is frequent in cases of hemorrhage because of the loss of iron-rich blood.
