Decreased kidney function

Hi,

During a normal checkup my blood test came back as showing a "slightly decreased kidney function". At least that's how my doctor described it. I went back two months later for a more thorough blood test (I think he called it a renal panel).

This time, the results showed my kidney function was improved over last time, but still abnormal. The numbers confuse me, but I think he said my Creatinine levels for the first test were 1.8 and now were 1.27.

Anyway, since they are still abnormal he wants me to see a nepharologist. I'm a bit of a hypochondrian and am freaking out! What's the worst case scenario? Are my kidneys failing? Am I dying? Will I need dialysis? I always feel like my questions never get answered by doctors.

I should say that in the past, I drank almost no liquids. I'd go all day without drinking a single thing other than a few cups of coffee and some sips of coke with a meal. No water, juice, or fruit like I see other people do. Since my first blood test I did try and drink more water. At least a glass a day. Can I be encouraged that this seemed to improve the blood test? I'd really appreciate any info on this. This is really worrying me. Thanks.
