Anemia affects nearly 1 in 2 patients with CKD Stage 3 to 5. The prevalence of Anemia increases as kidney function declines, and up to 90% of patients with CKD Stage 5 may develop Anemia if left untreated
It is a condition in which the body does not have enough healthy red blood cells (RBC) or haemoglobin to carry adequate oxygen to the body's tissues. As a result, people with Anemia often experience shortness of breath, tiredness, weakness and reduced physical capacity
Anemia can occur for many reasons. In patients with Chronic Kidney Disease (CKD), Anemia is one of the most common complications and becomes more frequent as kidney function declines. Key causes include:
Iron deficiency, along with Vitamin B12 or folate deficiency, directly restricts the body's capacity to build healthy red blood cells
As kidney function declines, the organs produce less erythropoietin (EPO), leading to a decline in red blood cell production
Blood loss, chronic infections or inflammation, and bone marrow disorders can also contribute to or trigger anemia
Kidney damage leads to anemia through direct hormonal and systemic pathways:
Regular follow-up with a nephrologist and routine blood tests are important for patients living with chronic kidney disease
Treatment depends on the underlying cause of Anemia and may include:
Iron supplements may be given by orally or intravenously (IV) to replenish iron stores and support red blood cell production
ESAs help stimulate the bone marrow to produce more red blood cells and are commonly used in patients with CKD-related Anemia
Vitamin B12 or folic acid may be prescribed when deficiencies are identified
In severe cases or emergencies, a blood transfusion may be required to rapidly increase hemoglobin levels
