Kidney Function Levels High. The major causes of increased creatinine levels are the same as the major causes of kidney disease high blood pressure and diabetes. Mild to moderate decrease in kidney function.
Petite people without much muscle mass will likely have a low kidney number. Urea nitrogen occurs as proteins from food break down and elevated levels may be a sign that the kidney is not filtering these waste products effectively. High blood pressure happens when the force of the blood pushing on the walls of your arteries is too high.
The human kidney naturally produces and filters creatine.
Normal levels of creatinine vary in individuals based on age and muscle development. This will vary between men and women and it is dependent on muscle mass. A gfr in the range of 60 to 89 percent is indicative of a patient with stage 2 kidney function. This stage is still considered to be mild kidney disease and patients might still not exhibit any symptoms.
