Chronic renal failure is the progressive deterioration of the glomerular filtration below 60mil / min, which leads to a retention of urea and nitrogen products. This process alters the electrolyte and acid base balance. In addition, there is a decrease in the production of hormones such as erythropoietin and vitamin D, as a result of the rapid loss of the ability of the kidneys to eliminate waste.

Causes and symptoms

The most frequent causes of chronic renal failure are other diseases. These are, in order of frequency, diabetes mellitus , arterial hypertension , glomerular diseases and genetic causes.

Clinically, chronic renal failure can go unnoticed until very advanced stages of the disease, hence the importance of early diagnosis. The disease can manifest with recent high blood pressure, bloody urine, swelling of hands and feet, fatigue or increased nocturnal urination. The decrease or absence of diuresis, loss of appetite, nausea, vomiting are also symptoms of chronic renal failure.



The best treatment for this disease is none other than prevention. The patient must avoid and treat diabetes, obesity or hypertension. Each cause has a specific treatment, with which the diagnosis is fundamental. In the case of not being treated, the consequences can be the severe loss of renal function. At that time, we must consider a treatment that replaces renal function through kidney transplantation or dialysis.
