Lately I have been noticing bubbles in my urine. Some of the time (mostly in the evenings) there are none. Mornings and early afternoon there seem to me more. Nearly every time there are bubbles they are few in number and dissipate fairly quickly. Occasionally they are significant in number (once every two days or so) and more foamy. I have been on weight watchers and have been losing weight (15 pounds in about 3 1/2 months). I drink a lot of water and do urinate somewhat frequently but I have been doing that for as long as I can remember (about 100-150 ounces a day). I am male, 35 years old, 205 pounds, 5'10" with no history or diagnosis of disease. I have noticed my urine comes out quite forcefully but as I've gotten concerned about the bubbles I sit down and try to let it out slowly. I still see some bubbles along the edge of the bowl that accumulate and then dissipate fairly quickly. Should I be concerned?
