The Doctor said that it can be possible that my wife is dehydrated or nevertheless she has a renal problem. If it's a renal problem, they would still need to findout what is causing it, and the wife needs to be hospitalized to do some lab tests. Thank you for the info, hope i can get some more ideas.
Did you ask your doctor what it means? Something tells me it has something to do with one of three things...the high/low levels of sugar, iron, or protein, in the blood. I'm not a doctor, It's just a hunch : ) please let me know what you find out.
