Kidney Disease: What Is the Dangerously High BUN Level

Healthy kidney can clear extra urea nitrogen away from our body, so kidney impairment is always accompanied with elevated BUN (Blood Urea Nitrogen) level. We should be alerted if BUN keeps increasing, because it is very dangerous. Well, what is the dangerously high BUN level?

BUN level goes up when half of kidney function is impaired

Urea nitrogen is a substance with small molecular weight, so it can pass through kidney freely. That is to say, as long as our kidneys are work normally to filter our body, BUN level stays in normal range 3.5-7.1mmol/L or 9-20mg/dL. According to clinical studies, BUN level goes up when about half of kidney function is impaired, because mildly damaged kidneys are still strong enough to help us eliminate extra urea nitrogen. For this reason, high BUN level always indicates serious kidney problems.

It is hard to answer this question with a number, because our body has different reaction on same BUN level. In general, people with a very high BUN level always experience lots of physical discomforts like nausea, vomiting, and skin itching. These problems means different parts of their body have been severely damaged by high BUN level.

You might be suggested to start dialysis when your BUN level becomes very high, but if you are in China, you will be treated with a systematic Chinese medicine treatment which is composed of Micro-Chinese Medicine Osmotherapy, Mai Kang Mixture, Foot Bath and Medicinal Soup. This systematic Chinese medicine treatment can promote blood microcirculation in kidney, activate kidney intrinsic cells, repair injured kidney tissues, alleviate renal ischemia and renal anoxia, all of which help to restore kidney function. We know high BUN level is due to impaired kidney function, so after this systematic treatment, BUN level goes back to normal range gradually.

All in all, BUN level is an indicator of kidney condition and it increases with decline of kidney function. Therefore, if we want to keep it in normal range, we need to strengthen our kidney and make sure our kidneys can work normally.
