Chronic kidney failure occurs as the kidneys gradually lose the ability to remove waste and excess fluid from the blood. At its most advanced stages, it’s known as end-stage renal disease. There are numerous underlying conditions that can lead to chronic kidney failure, including diabetes, high blood pressure, glomerulonephritis, recurrent kidney infections, and prolonged urinary tract obstruction due to an enlarged prostate, kidney stones, cancer, and other causes.
Both types of kidney failure can be fatal if not timely and appropriately treated.
Most Common Causes of Renal Failure
After diabetes and high blood pressure – the most common causes of kidney failure – other causes generally fall into one of these three broad categories:
