Symptoms and diagnosis of kidney failure

When the kidneys do not function properly, the body is gradually poisoned by waste products that are no longer eliminated. In chronic insufficiency, kidney damage is gradual, hence the need to act as quickly as possible. From symptoms to diagnosis, learn how to eliminate this silent disease.
When can a disease manifest only when symptoms are at an advanced stage? This is the puzzle of kidney disease management. Chronic kidney disease is silent. “We can live without knowing that our kidneys are not working at 100% capacity,” Brigitte Lantz I, secretary-general of the Kidney Foundation and adult dialysis specialist at Necker Hospital in Paris, told SELF. She cites kidney stones as a counter-example: “Renal colic is one of the only painful lesions of the kidneys.”
However, patients may experience some warning signs, even if there are no specific kidney problems:

frequently need to urinate.
The urine is dark, turbid, foamy, and weak.
bad taste in the mouth.
bad breath
Anorexia.
nausea;
vomiting;
Shortness of breath;
Constant itching
night cramps
Swollen eyelids and/or ankles…
diagnose
In addition to the presence of these symptoms, the doctor may suspect kidney disease if there is an abnormality in the kidneys: protein or blood in the urine, disease in the urinary system or kidneys, frequent infections of the upper urinary tract… or face the risk of developing kidney disease: family history For kidney disease, diabetes, high blood pressure, heart failure, liver failure, gout, prolonged intake or regular consumption of nephrotoxic drugs…

In certain circumstances, the health care professional will also have to check the health of the kidneys, before prescribing certain medications such as aminoglycosides, nephrotoxic chemotherapy, or iodinated contrast products for medical imaging techniques, or before certain metabolic disorders.

Chronic renal failure corresponds to the progressive and irreversible destruction of the ducts (nephrons) that make up the kidneys. Then it seems that only a third of these chains are still in operation.

This gradual decrease in kidney function is diagnosed by a permanent reduction in the glomerular filtration rate (GFR), measured directly by creatinine clearance or estimated from the serum creatinine level by a blood test. The glomerular filtration rate represents the number of milliliters of plasma that the kidneys can eliminate in one minute of this substance of muscle origin.
