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