I had norovirus on vacation and was vomiting and diarrhea for 24 hours and then flew on a plane and did not drink or eat much. 24 hours later I had my yearly labs and my creatinine was 1.57. It is usually 1.1 to 1.3 and has been for 20 years. I am 65 years old and very, very active... bike 3 hours daily, also use weights three times a week and swim. Doctor thinks test was high because of dehydration. I take lipitor and my cholesterol is 147. Should I be worried. Wants test repeated in November.
