Like creatinine, blood urea nitrogen is also a common standard to judge patients’ kidney condition. There are patients asking what blood urea nitrogen 9 means, and it is necessary for patients to have a better understanding on this aspect.
What is urea nitrogen?
Urea nitrogen is a major production of protein. As we know, the major ingredient of protein is amino acid, while when the amino is removed by decomposition, NH3 and CO2 will be produced,and these substances will form urea nitrogen in liver.
One gram of protein can produce 0.3g urea, and the ratio of nitrogen in urea is 28/60, and it is about half. Thereby, the nitrogen content in protein is very large.
Like creatinine, urea nitrogen is a metabolic waste to our body, and it will be excreted out by our kidneys.
what does blood urea nitrogen 9 mean?
The normal blood urea nitrogen level is 3.2~7mmol/L. For patients whose blood urea nitrogen is 9mml/L, if their high blood urea nitrogen is caused by their kidney damage, they may think they just have a mild damage in their kidneys.
In fact, our kidneys have strong compensation, which means if there is any part of our kidneys being damaged, other parts will replace it to complete kidney work. What’s more, if there is more than half of kidney function is normal, there will not be any problem caused by kidney damage.
That is to say, when patients’ urea nitrogen level is 9mmol/L, they already have more than half’s kidney damage. Certainly, they are in a severe kidney damage condition.
Thereby, when patients find their urea nitrogen is 9mmol/L, they should see a nephropathy doctor as soon as possible. They need to accept right treatment and change their life habits and diet to protect their health condition and kidney function. Besides, it is very important for patients to have confidence and good emotion to deal with their condition.
