I went to the doctor last week because I've been feeling tired/drowsy/depressed for about as long as I can remember. I'm 28, about 6 ft tall, 185 lbs, athletic build. He ordered a blood test.

The blood test came back that, on top of having extremely low testosterone, my kidney values were all over the place. My creatinine number showed as 7.4 (normal is apparently less than 1.9). My EFGR score came in at 4.

I have been consuming a rather high amount of protein due to trying to build muscle, and I also supplement creatine. Could that be enough to cause those values or do you think I have something to worry about.

Thank you very much.

Welcome to e health forum.

The medical test results need to be assessed along with consideration of your clinical examination findings and other medical issues that you might have.

Although many forms of kidney disease do not produce symptoms until late in the course of the disease, there are six warning signs of kidney disease:

1. High blood pressure.

2. Blood and/or protein in the urine.

3. A creatinine and Blood Urea Nitrogen (BUN) blood test, outside the normal range. (BUN and creatinine are waste that build up in your blood when your kidney function is reduced).

4. A glomerular filtration rate (GFR) less than 60. GFR is a measure of kidney function.

5. More frequent urination, particularly at night; difficult or painful urination.

6. Puffiness around eyes, swelling of hands and feet.

The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion.

If all other parameters other then the creatinine levels are normal, then the elevated nos could be due to the dietary intake of muscle building supplements.

Consult your doctor for a proper advice.
