In individuals with chronic kidney disease, which type of anemia is frequently observed?

In individuals with chronic kidney disease (CKD), normocytic anemia is frequently observed due to several interrelated factors. The kidneys play a critical role in the production of erythropoietin, a hormone responsible for stimulating the production of red blood cells in the bone marrow. When kidney function declines, the production of erythropoietin decreases, leading to reduced red blood cell formation.

Normocytic anemia is characterized by red blood cells that are of normal size but are present in lower amounts. This type of anemia can manifest as a consequence of chronic disease, where the body is unable to adequately compensate for the loss of red blood cells. Additionally, in CKD, there may be a relative deficiency of iron due to impaired utilization, along with a reduction in red blood cell lifespan which contributes to the anemic state.

While macrocytic anemia involves larger than normal red blood cells, it is typically associated with vitamin B12 or folate deficiencies, which are not primarily linked to CKD. Microcytic anemia usually occurs due to iron deficiency or chronic disease, but in the context of CKD, the anemia is more often normocytic. Hemolytic anemia is characterized by the premature destruction of red blood cells and does not
