Anemia is a common complication of chronic kidney failure, especially kidney failure in end stage. Anemia is a condition in which the body has fewer red blood cells than
normal. Red blood cells carry oxygen to tissues and organs throughout the body
and enable them to use energy from food. With anemia, red blood cells carry less
oxygen to tissues and organs—particularly the heart and brain—and those tissues
and organs may not function as well as they should.
How is renal anemia caused by chronic kidney failure?
Chronic kidney failure is marked by the progressive loss of kidney function. Kidney is a very important organ with function of filtering blood, producing urine, keeping balance of electrolyte, secreting hormone and keeping water balance. For chronic kidney failure patients, their kidney function is impaired, and as a result, kidneys fail to function properly. Under such a condition, kidney can not secrete a hormone named EPO which is very important for the formation of red blood cell. Damaged kidney produces less EPO, and consequently, production of red blood cells reduce. Anemia appears when red blood cell account in blood is lower than normal range.
Symptoms of renal anemia
Renal anemia always bring lots of symptoms which go as follow:
weakness
fatigue, or feeling tired
headaches
problems with concentration
paleness
dizziness
difficulty breathing or shortness of breath
chest pain
Although renal anemia is a complication of chronic kidney failure, if left uncontrolled, it will worsen kidney condition. Therefore, treatment is urgently needed to bring it control once kidney failure patients are told to have renal anemia.
