Anemia and renal insufficiency have a relationship?

Anemia, it seems that with renal insufficiency nothing, but in fact, this really true? Most people believe that, so-called anemia, nutritional anemia caused by malnutrition, as long as maintenance, adding nutritional supplements, it should be will be improved. Some doctors only folic acid, iron and blood oral solution for treatment. So, anemia and renal dysfunction how kind of relationship, let's take a look.
In many cases, the primary disease symptoms can be very subtle, mild, as usual cold, complicated by mild or occult glomerulonephritis may be due to repeated colds, but the symptoms are light and did not care. After a long process, the progression to chronic renal insufficiency, and the emergence of the digestive tract as the main symptoms of renal anemia.
Kidney chronic nephritis or acute lesions of chronic renal insufficiency, erythropoietin hormone level will drop, the ability of the patient's body to manufacture red blood cells decreases, so the patient will show symptoms of anemia. Combined with patients with no apparent history of kidney, part of the patients are often mistaken for iron deficiency anemia, refractory anemia, aplastic anemia, which delays the diagnosis and treatment of disease.
Renal anemia is due to various causes kidney damage, renal insufficiency, and reduced renal function, excretion of reduced metabolites, retention increased. These chemicals inhibit erythropoietin generated on the one hand, on the other hand, inhibit the activity of erythropoietin, resulting in the destruction of the red cell membrane and shorten its life. Due to renal insufficiency and long-term anorexia, diarrhea, caused by lack of iron, folic acid, vitamin B12, and ultimately lead to renal anemia.
Through the above description, I believe that the anemia have sufficient knowledge, you can see, anemia is also common symptoms of kidney disease, even in normal urine, have to do routine urine examination. Once the urine proteinuria or hematuria, associated with abnormal blood pressure, then tend to have the possibility of renal anemia, and must continue to do blood, kidney function, kidney B ultrasonic examination, so that we can quickly diagnosed. Therefore, anemia appears to be simple, but they can not be overlooked.
