Anaemia occurs in patients with chronic kidney disease due to:
A
Decreased erythropoietin production
B
Decreased renin production
C
Decreased plasma osmolarity
D
Decreased plasma osmolality
Correct Option:
A
Explanation
Healthy kidneys produce erythropoietin, or EPO, which stimulates the bone marrow to produce red blood cells. In chronic kidney disease, reduced EPO production commonly causes a normocytic, normochromic anaemia. Reduced renin production or changes in plasma osmolarity are not the primary cause.
