Question: Foamy Urine

 p1o2i3u4 - Sat Feb 26, 2005 11:58 pm

I have had foamy urine for few months now. It happens every time I go. When I read about it on-line, the impressions that I got are a) it implies a major kidney problem and b) it is often associated with other symptoms, like edema.
My questions are: 1. Are my impressions correct?
2. Can the foam in urine be caused by some benign process or is it always the case that kidney disease is involved. The reason I ask is because some people mentioned that they have foamy urine but their urine protein tests come back negative.
3. I've had some foam in my urine for as long as I can remember, so how much foam is too much?

Thank you very much.

User avatar Hi p1o2i3u4,
A foamy appearance of urine may indicate numerous conditions, kidney disease, kidney failure from diabetes, urinary tract infections etc. I wouldn't consider a urinary tract infection since it has been long standing. Is your urine a normal yellow color? Any swelling? A urinalysis and a microalbumin study (24 hour urine collection) are a couple of easy methods to determine kidney function. If these tests came back normal then I wouldn't give it much concern at this time. It may be something as simple as a forceful flow of urine that could make a foamy type of appearance.
