Joggers' Hematuria

I almost moved this blog to WordPress until I realized how many strings were attached, so to speak.

Anyway, it is my hope that I can drive more traffic to this blog so that in addition to all the other things I write about, I can make Public Service Announcements (PSAs) like this one:

Don't run on empty.

If you've ever heard the Diana Fox song "Running on Empty" while doing your tenth mile, you probably thought about your heavy legs or some other "wall" that you have to push through. However, I'm not talking about energy reserves... I'm talking about pee.

It makes sense to relieve yourself before a run. After all, who wants to think about the port-a-potty on top of everything else a runner has to worry about? But unless you really need to, refrain. Or, get some liquid in you soon after.

Hematuria is the medical term for having blood in the urine. It can be caused by many things, including scary things like kidney disease, stones, etc. One less harmful cause is strenuous exercise, including running long distances, also known as "joggers' hematuria." Even if exercise is the culprit, the next question is: why? One possibility is that an empty bladder's walls can rub up against each other and cause capillaries to break. Many marathoners have the condition after races. Bicyclists can get it because of "impacts" to "that" area.

There are other specific causes/origins, so if you ever find blood in the pee, get it checked. Stay hydrated!

  1. The urge to pee almost always shows up at the most inopportune time. I think having a little bit of pee in there is good but too much and it is not comfortable to run with. Interesting article tho.

  2. I did not know that running or jogging can cause hematuria. Thanks to your article, I'm now more informed about it, and can now take the necessary precautions.

  3. I have had "runners bladder" before, man the tests were the worse part. Low and behold I have it right now, heading to the doc in the AM.

  4. thanks for the tips and information..i really appreciate it.. Best Joggers for Men
