If a patient has high urea nitrogen and creatinine at the same time, it means that the patient has kidney function problems. Urea nitrogen and creatinine are the general term for metabolic waste in the body, and they are an important indicator for kidney function testing. The simultaneous elevation of urea nitrogen and creatinine indicates that the patient’s kidney function is damaged, and then we should actively look for the cause of kidney damage and creatinine-lowering treatment. If the damage of kidney function is caused by high blood pressure and diabetes, you should actively control blood pressure and blood sugar to keep them at a reasonable level. On the basis of controlling blood pressure and blood sugar, creatinine-lowering treatment can be given, and drugs such as urinary toxicity Qing granules and Haikun kidney hi capsules can be applied to treat the condition, which should be better controlled or improved through the above treatment.
