Why Does Urea Nitrogen Increase

Why Does Urea Nitrogen Increase Blood urea nitrogen (BUN) is one of main indicators of renal functions. In medicine, blood urea nitrogen is usually used to reflect the urea level in blood. Urea being discharged from the body by kidney, if the urea level is higher than the normal, it means that there are some underlying problem.

What is the normal urea nitrogen level?

As for healthy adults, the BUN level is 3.2-7.1mmol/L (9-20mg/dl) on an empty stomach. If your BUN is higher than the normal range, you should find out the reasons actively. Various reasons can cause urea nitrogen to increase. Please go on reading the followed details.

What are the reasons to cause BUN level to increase?

As a matter of fact, the main reason is kidney damage, such as glomerulonephritis, interstitial nephritis, acute and chronic renal failure and so on.

Kidney is responsible for eliminating toxins and excess wastes in blood, thus kidney damage will directly cause BUN to increase. However, due to the strong compensatory ability of our kidneys, BUN can be in the normal range in the early stage of kidney damage. BUN level does not increase obviously until the GFR is less than 50%.

If patients’ BUN level is higher than the normal, they should take effective treatments immediately to manage their healthy condition. Chinese medicine treatment is a good option without side effects to patients’ body.

Apart from kidney damage, there are also other reasons to cause high BUN.

Intake of too much food rich in protein: urea is the byproduct of protein metabolism, thus intake of excess protein will increase urea level.

Dehydration: due to diarrhea, nausea and strenuous practice or lack of water intake, people may suffer from dehydration that causes blood to concentrate, leading to the increase of BUN level.

Besides, many other reasons can also lead to high urea nitrogen, such as serious infection, diabetic acidosis, severe burn and gastrointestinal bleeding and so on.
