The kidneys produce a hormone called erythropoietin (EPO) that stimulates blood cell production. When kidney function declines, patients may develop anemia, characterized by a low red blood cell count.
EPO requires iron to manufacture blood cells effectively. While a balanced diet typically provides sufficient iron, kidney patients often need additional supplementation through oral medications or intravenous administration.
Red blood cells transport oxygen throughout the body. Without adequate oxygen delivery, tissues and vital organs like the heart and brain may not function optimally. Anemia frequently prevents kidney disease patients from feeling their best, but appropriate medical interventions can improve energy levels, longevity, and quality of life.
Laboratory Tests
A complete blood count (CBC) measures hemoglobin (Hgb) levels in a blood sample. Hemoglobin is the oxygen-carrying component within red blood cells.
Onset Timeline
Anemia may develop during early kidney disease stages when kidney function remains between 20 and 50 percent of normal. The condition typically worsens as kidney disease progresses.
Diagnosis
Hemoglobin levels of 11 or lower indicate anemia, with decreased EPO production as the likely cause. Physicians conduct evaluations including tests for iron deficiency and gastrointestinal blood loss to exclude alternative causes.
Treatment Options
- Consuming iron-rich nutritious meals
- Iron supplementation via oral pills or intravenous administration as recommended by your nephrologist
- EPO injections administered subcutaneously or intravenously per physician guidance
