The task of the kidneys is to clean the blood of unnecessary waste products. Renal failure is a condition in which their filtration ability is impaired. Improper renal excretion may be acute or chronic. Acute renal failure occurs suddenly, but its effects can be reversed. In the case of a chronic disease, irreversible damage to the glomeruli occurs.
Kidney failure - causes
It may be the result of insufficient blood supply to the kidneys, their diseases or obstruction of the urinary tract. Kidney failure also appears as a result of diabetic nephropathy, hypertension, and blood vessel disease.
Kidney failure - symptoms
The most characteristic signs of renal failure include oliguria and anuria. There is an increase in blood creatinine, vomiting, diarrhea or swelling of the upper and lower extremities may occur. Acute renal failure can lead to pulmonary edema and thus breathing problems. If the disease is chronic, it is accompanied by fluctuations in blood pressure, thirst and pollakiuria.
Acute renal failure - treatment
Unlike chronic renal failure, acute is reversible. The treatment consists in eliminating the cause of the disease, i.e. removing toxic factors, urinary stones, etc. Acute renal failure detected too late can lead to irreversible damage.
