Q
  1. Why do people with advanced kidney disease commonly become anaemic?
A
  1. Why do people with advanced kidney disease commonly become anaemic?

Answer: In many cases of kidney disease, the cells responsible for producing erythropoietin are damaged or destroyed. The reduction in erythropoietin levels leads to reduced erythropoiesis and fewer red blood cells, resulting in anaemia.
