    What Causes an Elevated BUN Level in CKD patientsFor patients with kidney disease, an important aspect they should care is their BUN level, which is a significant standard to learn about their kidney function. Elevated BUN is dangerous, because it often indicates severe damage in patient’s kidney. Well then, why elevated BUN is dangerous? What causes an elevated BUN in CKD patients?

    Why elevated BUN is dangerous?

    BUN is a major metabolic product of protein, and it should be filtrated out by kidney. Kidney disease can damage patient’s kidney function, and when patient’s kidney function is damaged severely, that will cause patients to have high BUN level.

    However, it is not easy for patients with kidney disease to have elevated BUN, because our kidney has strong metabolic ability, and half normal kidney function will be able to guarantee our body health. Thereby, if patients have elevated BUN caused by kidney damage, that means at least more than half normal kidney function has been damaged.

    What causes an elevated BUN in CKD patients?

    As we have said, kidney damage is the most common cause of elevated BUN in patients with CKD, and its level is also used to assess patient’s kidney function. In this case, high BUN is caused by patient’s low kidney function, and it will be continuous.

    Besides, patient’s BUN level can also be affected by many other factors, which can also cause patients to have high BUN. For example, when patients increase much protein intake in their diet, that will be able to cause patients to have high BUN. If patients have dehydration, a large amount of ascites, fever, acute infection, etc, they can also cause patients to have high BUN. However, if patient’s elevated BUN is caused by these factors, that usually does not stay long, because when these problems are solved, patient’s BUN level will go down to normal.

    Kidney disease can cause many health problems, and patients should do what they can to improve their overall condition. If you have any trouble in dealing with your condition, you can send your details and problem to ***. We can provide the guidance you need or do what we can to help you.
