Fatigue and weakness: Chronic kidney disease can cause fatigue and weakness due to the buildup of toxins in the body that the kidneys cannot eliminate.

Anemia: Anemia is a condition in which there is a shortage of red blood cells in the body. Chronic kidney disease can cause anemia due to a decrease in the production of a hormone called erythropoietin, which is produced by the kidneys and stimulates the production of red blood cells.
