Causes
The most common causes of chronic renal failure in North America are diabetes mellitus (type 1 or type 2 diabetes) and high blood pressure. The most common cause of end-stage renal failure worldwide is IgA nephropathy. One of the complications resulting from diabetes or high blood pressure is the damage to the small blood vessels in the body. The blood vessels in the kidneys also become damaged, resulting in chronic renal failure.
Other common causes of chronic renal failure include:
- recurring pyelonephritis (kidney infection)
- polycystic kidney disease
- autoimmune disorders such as systemic lupus erythematosus
- urinary tract blockages and reflux (due to frequent infections, stones, or an anatomical abnormality that happened at birth)
- excessive use of medications that are metabolized through the kidneys
