Anemia is a complication of kidney disease caused when the body does not produce enough healthy red blood cells. Red blood cells carry oxygen to organs and tissues throughout the body. Fewer red blood cells means less oxygen. With less oxygen, organs and tissues cannot function well, the result being you to feel weak and tired.
Healthy kidneys produce the hormone erythropoietin (EPO). EPO tells your bone marrow to make red blood cells. If kidneys are damaged and cannot make enough EPO, your bone marrow will not produce enough red blood cells depriving the body of the oxygen it needs.
The symptoms of anemia are:
- Chest pain
- Problems concentrating
- Difficulty breathing
