What Causes A Person’s BUN Level To Increase
BUN refers to blood urea nitrogen, which is a common standard to assess patient’s kidney function and body health condition. And for patients with kidney disease, a common condition that often appears in their body is high BUN, and that is often a bad sign of patient’s kidney condition.
What can cause a person’s BUN level to increase?
High BUN can be caused by many factors, such as severe dehydration, fever, acute infection, massive hemorrhage in upper gastrointestinal tract, etc. But high BUN cause by these factors usually can not exist for a long time, and it will recover to normal when these factors disappear.
But for patients with kidney disease, high BUN level is a common condition in their bodies, and that is caused by patient’s kidney damage.
BUN is a major end product of protein, and it should be filtrated out by kidney. Kidney has the function of filtrating out the metabolic wastes from patient’s blood so if patient’s kidney function is damaged, the wastes that should be filtrated out will accumulate in patient’s body, which will cause high BUN, and high BUN caused by kidney damage will be persistent.
What can we know if patients with kidney disease have high BUN?
As we have said, high BUN is common in patients with kidney disease, and it is a dangerous sign.
Our kidney has strong metabolic ability and strong compensation, and half normal kidney function will be able to guarantee our body health. As a result, patients with kidney disease will not have high BUN unless more than half kidney function is damaged.
Beside, the lower patient’s kidney function is, the higher patient’s BUN level will be. And if patient’s BUN level reaches 60mg/dL, it is a sign for patients to consider whether to accept dialysis.
Thereby, high BUN may be nothing serious, and it can also be very dangerous. If you have kidney disease, you should be careful in dealing with it.
