What does it mean when you have foamy urine? Should I be concerned if it doesn't go away after a few days?

Answers from Erik P. Castle, M.D.

Passing foamy urine now and then is normal, for the speed of urination and other factors can influence this. But you should see your doctor if you have persistently foamy urine that becomes more noticeable over time. This can be a sign of protein in your urine (proteinuria), which requires further evaluation. Increased amounts of protein in urine may indicate a serious kidney problem.

If your urine seems unusually foamy most of the time, your doctor may recommend that your urine be checked for elevated levels of protein. If the test is positive, you may need further tests to determine the cause of the problem.

What is foamy urine a sign of? Ever since I went paleo five months ago my urine has been foamy. Any idea what it could be? I eat VLC and very high fat. I consume no fruit, nuts, dairy, or starchy vegetables. Could it be a problem with my kidneys?

Answer by Kashkillz 3483 · Jan 12 '13 at 08:16 PM Protein won't damage healthy kidneys. But, if your kidneys are already a mess for whatever reason, excessive protein will be dangerous. This is due to it building up... NOT being excreted. So basically, if you're eating a high protein diet, when your urine's NOT foamy is when you need to worry.

I have been researching foamy urine for over a month. The foamy urine could be caused by anything as a urinary track infection or a chronic kidney disorder. I am a diabetic, so this is a huge concern for me. After my anxiety totally drained me, i decided to make an appointment with a kidney specialist called 'nephrologist' to ease my mind. The bottome line is that you need blood work to see what your GFR, Bun / creatine functions are. Get a copy of the results and compare it to the 'normal range'. Not eating dairy products and fish and drinking 8-10 glasses of water has significantly helped in flushing my kidney / urinary system...Go to a specialist.

Sometimes you may experience this foamy urine or bubbly urine after eating a lot of fish, chicken and other meats. These meats contain muco-proteins. People who take a lot of protein supplements, such as whey protein powder, may see this bubbly urine as well. Why is this? Well, if your body is not breaking down these proteins efficiently, the protein is usually expelled from your body in your urine. The proteins, when combined with the air, then produce a foamy or bubbly urine. Proteinuria caused by eating too much protein in your diet is, of course, temporary, and the proteinuria should diminish as you reduce the amount of protein you are consuming.
