What does bubbles in urine mean?
Probably just air that got mixed into your urine steam. Or are you urinating underwater (in a tub?) and watching the bubbles escape from your urethra? If that's the case ... maybe ask your doctor.
drinking beer does it to me. What goes in your body comes out. A little bubbly is no big deal usually if it's on and off.
pour water into the toilet it will do the same thing. it has nothing to do with protein or carbonation
probably due to high protein in your urine?
Too many bubblebaths.
