Kidney is an important organ to maintain the stability of the body environment, through the generation and excretion of urine, metabolites excreted, to maintain acid-base balance, in addition to the function of conditioning endocrine.
Chronic renal failure is a group of syndromes consisting of various chronic kidney diseases (chronic nephritis, one of the most common causes of chronic renal failure in China) caused by progressive, severe metabolic disorders and other impairments. It is a slow irreversible Process, early and mid-term symptoms are often not obvious. When the renal function damage to a certain extent, the body of toxins can not be excreted through the kidneys, will seriously damage the various organs function, and even life-threatening. At this point, due to renal excretion disorders caused by metabolic acidosis; renal filtration function damage, leading to water, sodium retention, and water, sodium retention has led to the onset of heart failure. If the body of the high toxin state can not be timely and effective relief, will make the heart and other organs involved in heart and brain.
Dialysis therapy is simply based on the semi-permeable membrane "membrane balance" principle, the use of a certain concentration of dialysis solution and the accumulation of metabolites in the blood, water, electrolyte for osmotic exchange, removal of metabolic waste and excessive water, Electrolyte in the safe concentration, instead of the kidney can not work to exercise its excretion function, the toxins from the body, which play a rapid relief of uremic symptoms. Therefore, for patients with advanced renal failure in a timely manner to dialysis, to help the kidneys metabolism, discharge of waste, relieve symptoms of systemic poisoning, to prevent serious complications is particularly important.
The above is about why do chronic renal failure patients need dialysis treatment, hope to help, if you have questions about kidney disease need a detailed understanding, you can consult our online experts, our experts will reply you as soon as possible of.
