Most of the time i've urinated today, my urine has had a moderate amount on bubbles/foam that disappear about a minute later. should i be worried?

Yes: You should at a minimum get a urine analysis on a freshly voided urine specimen. Ask yourself, has my diet changed recently, or have I started taking a supplement or have I started a new exercise routine that might be stressing my body in a way that is new for me? Returned from any foreign travel? Once you have answered all of these ?'s make an appt with your doc.

Watch it: if it happens just once in a while, it is ok. if it happens all the time, i would see a doctor. usually excess protein in urine causes bubbles
