Be aware of acute renal failure. Acute means sudden onset. The kidney function is rapidly lost and symptoms show up promptly. Fortunately the rapidity of recovery is also amazing if the cause is identified and effective treatments are taken right away.
Know that damage to your kidneys can cause acute renal failure. Examples of issues that could lead to kidney damage include severe sepsis, where the infection sets up widespread inflammation and toxin production that directly damages the kidney; certain medications that are known to cause kidney damage like painkillers, some antibiotics, anticancer drugs; or extensive muscle damage.
Learn about issues with the processing of urine that can cause acute renal failure. These issues are due to an inadequate blood supply to the kidneys. This could happen when the blood volume itself is low, such as large scale bleeding; severe fluid loss through vomiting, diarrhea, or sweating; poor water intake; medications that increase urine volume (such as diuretics); or an obstruction of the main renal blood vessels.
Find out if you have something blocking the flow of urine out of the kidney that could cause acute renal failure. Tumors or kidney stones may obstruct the ureter (the passage between kidney and bladder) or bladder outlet. An enlarged prostate gland may also impede urine flow. In all cases, there is a urine backflow towards the kidney that impairs its normal function.
Learn about chronic renal failure. This type of renal failure develops over many years. It silently kills the victim. Unfortunately often there are no initial symptoms. Most of the cases are progressive and irreversible. Common causes of chronic renal failure are:
Poorly controlled diabetes.
Long standing hypertension, which is high blood pressure.
Chronic glomerulonephritis, which is the inflammation of tiny filters in the kidney.
Some genetic diseases like polycystic kidney disease, Alport’s syndrome, Systemic Lupus.
Erythematosus, which is the inflammation of the skin.
Reflux nephropathy, which is the backwards flow of urine back into the kidneys.
