How to Lower High Blood Urea Nitrogen (BUN) in Kidney Disease

2013-03-08 17:01

Blood urea nitrogen (BUN) level is used to evaluate how your kidneys are functioning.High blood urea nitrogen level may indicate kidney impairment.

How does high blood urea nitrogen occur in kidney disease?

Urea nitrogen is the breakdown of proteins. A normal blood urea nitrogen level is between 7~20mg/dL,though these numbers can vary by laboratory. If your kidneys are not functioning, the byproducts of proteins will build up in blood, resulting in high blood urea nitrogen levels. Due to powerful compensatory capacity of the kidneys, its level does not increase until more than half of renal function is lost. However, an elevated blood urea nitrogen alone does not always indicate a kidney disorder.

How to lower high blood urea nitrogen caused by kidney disease?

A low-protein diet

As urea nitrogen is the byproduct of proteins, tight control of protein consumption of proteins is an important part in lowering high blood urea nitrogen levels. High-protein foods include red meat, poultry, fish and dairy. Beans, nuts and grains have moderate amounts of protein, and fruits generally have no protein.


Ketosteril is often prescribed to the patients when glomerular filtration rate(GFR) lowers less than 25ml/min. This medicine can utilize the nitrogen in inessential amino acid to synthetize amino acid, thus reducing the formation of urea in blood, thus lowering high blood urea nitrogen level.

Treatment of kidney disease

High blood urea nitrogen level is the result of kidney damage. Therefore, to lower the high level, the key role should be restoring the impaired kidney structure and improving renal function.

Micro-Chinese Medicine Osmotherapy is a natural treatment for lowering high blood urea nitrogen.This therapy can dilate renal arteries and increase blood supply to kidneys.Additionally, it can activate the self-repairing system of the kidney to improve the filtering ability of the kidneys.
