Renal pathophysiology · Physiology

Anemia in chronic kidney disease is mainly due to:

  1. Coexisting iron and folate deficiency
  2. Chronic blood loss through the urinary tract
  3. Reduced erythropoietin production
  4. Accelerated red cell hemolysis
Show answer and explanation

Correct answer: Reduced erythropoietin production

The kidneys produce erythropoietin, which stimulates red blood cell production. CKD reduces erythropoietin synthesis, leading to anemia.
