Question: my spouse recently had a medical test and found his creatinine level at 2.9 due to the fact that he has been high blood pressure for 3 years now. His doctor now change his BP drugs and advise him to start exercise and adjust his diet after one week of taking the new drugs, his BP become normal and the creatinine level came to 1.3. My question is this, can the creatinine level go down immediately just like that. Please respond.
Doctors: Long term high blood pressure can cause kidney disease. Creatinine is a kind of metabolic wastes, which is removed by the kidney. Once the kidney is damaged more than 50 %, creatinine builds up in the body, resulting in high creatinine levels. The normal creatinine level for adult male ranges from 0.7 to 1.3. Though his blood pressure and creatinine are brought to normal level through hypotensive drugs, exercise and proper diet, it does not mean the creatinine will not increase. Because the underlying causes are not found. With time going, his creatinine may increase again and then it can not be controlled easily. Does he have other symptoms, such as proteinuria, hematuria and edema?
Because your given information is too limited, I can not judge whether it is the high blood pressure that causes kidney disease. If you have the recent test report, please email to firstname.lastname@example.org, our nephrologists will give you the accurate diagnosis. The earlier he are diagnosed and receives treatment, the better prognosis he will have.
