Absolute iron deficiency anemia

Definition

Absolute iron deficiency anemia is a condition characterized by a lack of sufficient iron to produce hemoglobin, leading to reduced oxygen transport in the blood. It results from depleted iron stores and can cause symptoms like fatigue, weakness, and pallor.

5 Must Know Facts For Your Next Test

1. Absolute iron deficiency anemia is diagnosed through low serum ferritin levels and increased total iron-binding capacity (TIBC).
2. Common causes include chronic blood loss, inadequate dietary intake of iron, and malabsorption disorders.
3. Iron-rich foods such as red meat, beans, and fortified cereals are essential for prevention and management.
4. Oral iron supplements are typically the first line of treatment; intravenous iron may be necessary for severe cases or those with absorption issues.
5. Nurses should monitor patients for side effects of iron supplementation, such as gastrointestinal discomfort and constipation.
