BUN is the abbreviation of Blood Urea Nitrogen which can help to diagnose kidney problem. For a CKD patient, their usually have high BUN level because of the decreased kidney function and also the higher the BUN level is, the worse the kidney function is. Therefore, learning how to reduce BUN level is very meaningful for CKD patients.
Why BUN level increases after kidneys shut down?
Urea nitrogen is produced while protein is metabolized in our body and many conditions can cause high BUN levels like high intake of protein, drinking less water, renal ischemia and some kidney problems. Kidney is the major organ that help to discharge urea nitrogen out of our body. For a CKD patient, because of decreased kidney function, urea nitrogen can be not discharged, as a result of which, blood urea nitrogen (BUN) level increases.
Although BUN helps to measure kidney function, it is not a perfect index and this is because BUN level usually does not increase until a half of kidney function is affected. Therefore, high BUN always indicates kidneys have been damaged seriously.
How to reduce BUN levels?
BUN level increases quickly without taking any actions. Also, when it increases a certain level, dialysis will be needed to remove toxins in the blood. In our daily life, many measures can be taken to avoid the quick increase of BUN level such as limiting protein intake, they can not solve the problem radically at all.
BUN level increases because of decreased kidney function, so improving kidney function will be helpful for reducing BUN level. Chinese medicine has long history and some of them have been prove to be effective in improving blood circulation, against inflammation, against coagulation of blood and degrade extracellular matrix. Under the effects of these medicines, kidney function can be improved greatly. As long as kidney function is increased, much more urea nitrogen are discharged in time and BUN level is reduced effectively.
