Final answer:
Chronic kidney disease is related to anemia due to decreased production of erythropoietin (EPO), a hormone that stimulates red blood cell production.
Step-by-step explanation:
The relationship between chronic kidney disease and anemia is that decreased production of erythropoietin (EPO) is causing anemia. EPO is a hormone that stimulates the production of red blood cells in the bone marrow. In chronic kidney disease, the kidneys are not able to produce enough EPO, leading to a decrease in red blood cell production and ultimately causing anemia.
