question: My annual lab tests showed an elevate BUN, and elevated Liver enzymes. Should I be concerned? Last year the BUN was elevated but not as much and now the liver enzymes are elevated. I take daily glucophage, aldactone and was taking a fat burner for awhile.  I am 32 years old, female, 5'3" and 123 pounds. I have been retaining water and its getting out of control. I recently gained 15 pounds over the last 3 months. I exercise 5-6 times per week 60-90 mins of cardio each time. My T3 was LOW however my T4 WNL and my TSH on the low end of normal. I was diagnosed with insulin resistance after the birth of my second child in 2003. Any advice or insight to this issue?
