What is kidney failure

Kidney failure

In the case of kidney failure (renal insufficiency), a distinction is made between sudden (acute) and creeping (chronic) kidney failure. Acute kidney failure can have various causes: circulatory shock, diseases of the kidney itself or urinary outflow disorders due to an enlarged prostate or tumors. Chronic kidney failure or chronic kidney weakness is usually the result of a long-term kidney disease. Chronic kidney failure is most commonly caused by diabetes (diabetes mellitus), diseases of the kidney corpuscles (glomerulonephritis), kidney tubes (tubulo-interstitial diseases) or damage to the kidney vessels caused by high blood pressure.

In the case of acute kidney failure, the water that is not excreted collects in the body (edema). Above all, water retention in the lungs can be fatal. In addition, potassium salts that were no longer excreted paralyze the heart. With chronic kidney failure, the body is gradually poisoned. Patients eventually die of malnutrition or poisoning. Even with slow kidney failure, water may accumulate in the lungs and cardiac arrest due to blood potassium salts can occur.

In the early stages of chronic kidney failure, the patient is given medication and needs to be careful about their diet and fluid intake. Sooner or later, however, the blood will have to be purified either with dialysis or with the help of a healthy kidney that was transplanted from a deceased or living organ donor.
