Kidney Question

[jasonD2]

last summer I had a slightly elevated creatinine on my blood test for a routine physical. it was 1.4. doc wasnt too concerned but had me retest...second time it was a 1.7. i was really nervous but the doc said it was just a normal variant specific to my physiology. Had a urine analysis after and everything was negative. After I cut out all of my allergic foods and gluten I had another blood workup and my creatinine was back down to a 1.3 and everything else was normal. I felt much relief. Could the initial results have just been a fluke or is it possible I was developing kidney damage as a result of eating foods i was sensitive to? If the latter is a possibility, Im worried because i am going to do a 1-2 week gluten challenge for more testing and am not sure if this is gonna cause any problems. only explanation i could give for the upward trend in my creatinine was that I was retested after a week in NY where I was pretty much eating everything and drinking a lot woth my pals...plus i may have been dehydrated since it was a hot summer and was on a plane which can further dehydrate you. Anyway, am i being psychotic or is there any legitimacy to my concern? thanks
