The Causes of Fatigue in PKD Patients

The Causes of Fatigue in PKD PatientsMany PKD patients may feel fatigue easily and can not do normal work. When more and more kidney functions are damaged, fatigue will become more serious. What are the causes of fatigue in PKD patients?

Many PKD patients will suffer from anemia, which is the main cause of fatigue. Let’s see some causes that lead to anemia.

Kidney damage

Anemia is always related to the reduction of red blood cells. A healthy kidney can produce a proper number of erythropoietin(EPO) that is important to the generation of red blood cells. But for the people with PKD, cysts grown on the kidneys will get larger and larger and oppress the surrounding renal tissues. For that reason, damaged kidney can not produce enough erythropoietin and the amount of red blood cells which can bring oxygen to the organs will be reduced too. The patients will get fatigue easily without enough oxygen.


Most PKD patients with serious condition will choose dialysis which can also cause fatigue too. Many substances that is useful for our body will also be removed during dialysis, including red blood cells. With the decrease of it, patients will get fatigue easily. In addition, dialysis is a labor-consume process itself. Many people can not afford to the expense of dialysis.

Restrained diet

Many foods are restrained for PKD patients. Such as beans and its products, animal liver and high-protein foods that contain rich iron and folic acid, which can help generate red blood cells. With strict dietary restrictions, the amount of red blood cells will become less and less.

Anemia usually happens at the early stage of renal disease. At that time, about 20%-40% kidney functions still be retained. As long as you take effective methods to treat anemia, fatigue will be relieved and so other symptoms.
