Foamy urine - proteinuria or lack of water intake?
For over 3 years I noticed foamy urine off and on. The first time I noticed I went to doc, did a urine sample test and found small traces of urine by nurse. So I was then sent off to have lots of kindey test:
eGFR MICROALBUMIN/CREATININE MICROALBUMIN, UR, QN BUN BUN-to-creatinine ratio A1C Liver Panel Thyroid Panel ANA Panel CBC
This was 3 years ago. And recently had the same test done besides ANA, and all were normal again, even dipstick was normal. He said dipsticks do show false positives. The new MICROALBUMIN/CREATININE and MICROALBUMIN, UR, QN was done on 5/22/13 and again was normal. I even made appoinment with kidney doc and it seemed like he laughed me out of office when I showed him my results. He told me not to ever worry about it. Still I want to know why I still keep getting foamy urine when I dont drink water.
And all were normal. But I still notice lots of bubbles, sometimes it takes less than 2 minutes to go away. It looks foamy. I workout but only drink protein shakes 1-3 a week at most. I'm 31, good
What I noticed:
1. When I drink loads of water, I rarely see any bubbles and do not see any foamy appearance 2. I mainly see foamy appearance in morning 3. When I sit to pee, I see minimal if any bubbles or foamy appearance 4. If I hit the side of toilet I do not see anything
From what I taken, foamy urine is an early sign of kidney damage, proteinuria. However on many forums, many of the responsies to these questions are "GO SEE A DOC, IT'S PROTEIN LEAKING" but all responises are from non medical professionals.
This is what I read so far: "Far and away, foamy urine is not associated with any abnormality of the kidneys. There are some (I am one of them) who think that the foaming is related to a high velocity of concentrated urine flow and therefore is more of a curiosity than a threat to your health." -Newell R.

I understand your concern regarding your symptoms. It is good that initial evaluation and diagnostic tests were normal. This rules out any kidney conditions. Generally, passing foamy urine now and then is normal, and speed of urination and other factors can influence this. Drinking plenty of water is highly recommended. If it persists, monitoring of urine through urine tests may be done also. Take care and best regards.
