Symptoms of chronic renal failure

As different as were originally kidney disease, the symptoms of chronic kidney failure when they are always the same.


  • 1 What illnesses often lead to kidney failure?
  • 2 Symptoms of kidney failure in the latent stage.
  • 3 Symptoms of kidney failure in azotemicheskoy stage.
  • 4 Symptoms of kidney failure in the terminal stage.

the first stage renal failure (otherwise - chronic kidney disease 1 degree) clinic depends on the disease - whether edema, hypertension and back pain.Often, for example, polycystic or glomerulonephritis with isolated urinary syndrome, people generally unaware of their problem.

In the next stage (chronic kidney disease 2) compensatory ability of the kidneys are exhausted, they are not able to display all the end products of protein metabolism, and purine bases, and biochemical analysis of blood revealed elevated levels of toxins - urea, creatinine.It is the concentration of creatinine in routine clinical practice becomes an index of glomerular filtration

rate (GFR).Reduced glomerular filtration rate up to 60-89ml / min - is mild renal insufficiency.At this stage, it is no anemia, no electrolyte shifts, no hypertension (unless it is a manifestation of the source of the disease), only concern a general malaise, sometimes thirst.However, at this stage in the targeted examination can reveal decline in vitamin D and parathyroid hormone increase, although still far from osteoporosis.At this stage it is still possible to reverse the development of symptoms.

If efforts at the initial treatment of the disease and the protection of residual renal function do not succeed, then renal failure continues to increase, GFR is reduced to 30-59 ml / min.This is the third stage of CKD (chronic kidney disease), it is already irreversible.At this stage, symptoms, certainly indicating kidney function decline:

In severe renal failure (CKD 4, GFR 15-29ml / min)

CKD Stage 5, uremia, GFR less than 15ml / min.Actually, at this stage, the patient should receive substitution treatment - hemodialysis or peritoneal dialysis.

Hemodialysis machines without dialysis life expectancy of such patients is calculated in weeks, if not days, so patients need to get into the field of view of the nephrologist much earlier.

Thus, specific symptoms that allow the diagnosis of renal failure, developed relatively late.The most effective treatment is possible on stage 1-2 CKD when complaints are virtually absent.But the minimum examination - urine, general and clinical blood tests, give sufficient information.It is therefore important for patients at risk be screened regularly, and not just see a doctor.
