Can you urinate while defecating

Answer 1

First, I presume your use of "you" is referring to Mankind and not me, the writer.

In short, the answer is Yes.

All Humans, without a specific disease that prevents this and/or some unfortunate type of Physical {Tissue} obstruction, not only "can" do both simultaneously, but do so most of the time when beginning defecation. Urinating usually ceases before the of the function of defecation, but this is due to the relative amounts needing excretion -- which is as varied as the number of Humans alive who defecate.

If Your question was a truly legitimate question and not some type of time-wasting prank, I urgently suggest that You make Yourself an Appointment with an experienced Gastroenterologist Doctor or a General Practitioner Doctor/Family Medicine Doctor As Soon As Possible! Because, any Person of an age who can communicate by use of a Computer Keyboard on the internet asking that particular question, probably experiences this action seldom, if at all. And if is the case, that is not Normal and needs Medical attention immediately!
