Why Pee When Pooping?

Dear PoopReport,

I have a question: Why must you always urinate when you poop? What is the physiological reason? You certainly can urinate without pooping....

Just curious (I'm a nursing student).

-- Margret





Dr. Adams says:

This is an interesting question. There are many muscles (both voluntary and involuntary) that are involved in helping one to both urinate and pass stool. These muscles have dual functions -- holding urine and stool in, and passing urine and stool to the outside world. The muscles that help to hold in our stool are stronger and larger than the muscles that hold in our urine.

The primary muscles that function to hold in stool are the internal and external anal sphincters. The internal sphincter is a completely involuntary organ, and as stool passes through this sphincter, the muscle slowly relaxes. The stool then contacts the external sphincter, which is a completely voluntary organ. At this point, we sense that there is an increased pressure in our rectum, and we likely feel the need to defecate. If a toilet or other commode is close by, we sit down and voluntarily relax our external anal sphincter, and the stool passes through. If, however, we would rather not have a bowel movement at that moment, we voluntarily tighten our external anal sphincter, and the stool is retained in the rectum.

Control of urine is similar. The muscles are smaller, but the concept is the same. There is both an involuntary internal urethral sphincter and a voluntary external urethral sphincter. The internal urethral sphincter opens when pressures inside the urinary bladder are great enough; we can hold back the urine by tightening our external urethral sphincter, or we can urinate by relaxing this muscle.

So why do we often urinate when we defecate, but not vice versa? The main reason is that the muscles of the pelvic floor play a role in defecation and urination.

The pelvic floor muscles relax when we defecate. However, they will not necessarily have to fully relax when we urinate. But when the pelvic floor musculature does relax, in addition to allowing stool to pass, it decreases the tension in our urinary sphincters, allowing urine to flow. Because our anal sphincters are stronger than our urinary sphincters, it is easier for us to have control over our bowels than our urine.

Of course, we all don't have normal control over our bowels or bladder. There are many conditions that can adversely affect our bowel or bladder continence. Also, the control of urine and stool differ in men and women because the anatomy of the male and female pelvis are so different.

But that can be covered in another "Ask Dr. Adams". Or ask Dr. Ruth.

I definitely believe it is a muscular aspect. The vast majority of the time I do not pee when I poop. I suffer from MS and I have urinary retention and incontinence, so I am reliant on catheters to empty my bladder. I had a bladder function test done and I am able to feel the urge to urinate, but I'm not able to initiate any voluntary muscle activity in my bladder, obviously due to nerve damage.

The only time I ever pee when pooping is if I'm very, very, very full in my bladder. But pre-MS onset I always did. So based on my lack of muscular activity in my bladder I definitely believe it is due to muscular factors.

Dear Poopmaster, why is poop brown? Is it because of our wasted food mixed together to make the color brown? 2). How come when we poop the size is small, or the size is big? Why does our poop have different sizes? Why can't it be the same size of our colon?

I have always struggled with bowel movement issues since I was young. I even went to the emergency room one time because of severe pains and after x-rays, sonograms, and fingers placed in the worse possible place the doctor's diagnosis was that I was full of it. So, I was at my grandfather's house one day and I saw him taking the 15 Day Cleanse pills from Dr Max Powers, and he told me how good it was so he gave me a brand new bottle of it. I take it everyday (as part of a 15 day cleanse cycle - then I stop) and its just great. No cramping like a laxative. I recomend this to anyone who is not regular....

Cannot believe how many people evidently neglect the possibility of throwing TP down the toilet to eliminate splashing. It is so damn simple, and surely it can't be that hard to think of?

We all have one diaphragm, and it pushes both poop and pee, usually selectively (one or the other) but sometimes simultaneously. At night my pee is always slow and difficult, and I find that if I can fart forcefully, the pee usually comes more easily.

If you have to pee and poop at the same time,do it! Ac,that was a good decision to go pee at school. Poop can build up and press against your bladder,leading to some serious problems.

I only pee about 3 times a day... Once when I wake up, once right before bed, and once somewhere in the middle. I usually feel the need to poop in the late afternoon. What I usually do is sit, pee for the second (or third if I've had a lot of water that day) time of the day, and then start pooping.

I remember one time in high school I had been holding a poop in all day because I don't like pooping in public. We were switching classes to go to our second-last class of the day and I needed to pee so I went to the bathroom. I sat down and tried to pee, but it my body literally wouldn't let me. The poop started coming out instead. It came out quickly, with no pushing required. Once the poop was gone I was finally able to pee. I felt very relieved when I was done.

When I crap, I usually squeeze my dick through my legs in the middle. I think that might help you men. And when I poop, is it supposed to be that quiet? I cant even hear others or myself pooing. And I usually pee before i go in the stall and then a lot when I let out my shit. By the way, how long to most men take when they poo? I take about 40-50minutes which I think is way to long. Also when I crap, I wipe my asshole through the front side, is it supposed to be wiped from behind? And do you need to wipe while sitting or standing?

Rising Damp's picture

I suffer from very weak bladder control and more often than not, end up with damp knickers and pantyhose.
I decided recently that in order to not to endure this situation i would just wear pantyhose alone as it is very comfortable.
On a recent visit to my favorite Indian restaurant, I needed to pee badly and on finding the restroom I hastened to remove my pantyhose only to be unable to do so in time.
I sat quickly and let it all go! A stream of pee flowing quickly through my pantyhose. Feeling both relieved and awkward at the same time, I was about to pad down the dampness with tissue, only then to feel the immense urge to 'push' from the 'rear door'. In an almost uncontrollable manner the chili ignited runny poop gushed out, filling the rest of my pantyhose right up to the rear waistband!!!
Oh Hell!! What a stinking mess,,yep,, goes to prove the two are linked and when one goes, the other is sure to follow!!!

I can control whether or not I pee when I drop a fresh deuce - I find it to be optional, not necessary...especially in those situations when morning boner jams make it impossible to tuck it round.

Does anyone else possess this ability? Am I a urinary anomaly?

Hello, MR--yes, but if everyone has to poop, and you all do it in the same toilet without flushing between, and you all wipe (some using lots of paper), you might have trouble flushing down the combined load, resulting in multiple flushes and using more water. I'll not even mention what happens if you clog the unit . . .

Mall Rat's picture

Me and four of my friends spend a lot of time at the mall. It seems like once every half hour we visit the bathroom because one of us has to go. Sometimes I pee and poop at the same time. I know that saves water. Well, if I could convince each of them to work out some order in using the same stall one after the other, more water could be saved. So there is a conservation side to this topic, too.

Dear toilet paper pooper, I corrected your spelling except for the word "genious", I suggest you give that big dick a shake or two and see if you can hear a brain rattling around in it.

If you're trying to shit without the splash back just wad up some toilet paper and toss it down in the toilet. Do your thing and no worries about splash back! Thats right, I'm genious, also they need a little thing that you can attach to your legs for the big dick guys like myself, to hold it out of the water.. Just a thought.

Hello, Shelly--It sounds like more of a strategy issue than any bodily malfunction. Often when a person really has to poop, he or she also has to pee but can't feel it as strongly. Best thing to do is ready yourself for production at both exits when you have to poop.

This reminds me of one experience I had a few years ago when I was around 19. I went to the beach in a one piece bikini and sarong. I remember having to go to the bathroom badly, and so I ran off to the toilet stalls.

I had never really thought about peeing while crapping, and I didn't want to have to take off my sarong and bikini as I was lazy and it was just too much time and effort, I wanted to get into the water, so I ended up just reaching down and pulling aside the bum-part of my bikini only as the stretching wouldn't allow me to pull aside the part that goes in front of my "stuff" as well, and so I sat down, my bum pressing and holding it aside against the seat.

Unfortunately for me I didn't really consider the pee part as I thought I could hold it but I was proven wrong, and before I had even pooped, I farted really hard and instantly began peeing my bikini like no tomorrow whilst starting to poop. Because I was pooping, I couldn't just pull off my bikini or I would get crap all over my bikini, and because I was peeing so much I didn't want to get my hands icky, so all I could do was watch my knees knock inwards constantly and wait for my monstrous 3 minute pee to finish. I ended up with a wet but warm bikini (as I hadn't jumped into the water yet). I was lucky to be wearing my sarong, so I managed to walk outside and get straight into the ocean without anyone noticing.

I always thought this meant I had bad bladder/bowel control, but I guess not?

As a 67-year-old with enlarged prostate, I get up to pee 2 to 4 times a night, and I pee every few hours during the day; that helps prevent recurrence of kidney and bladder stones.

Often I poop soon after arising in the morning. If I can, I pee first, then sit down to poop. Almost always, after pushing out my poop, I can pee again--not seated, for the most part, but standing. I think the pressure from pooping sends more pee down the pipe and lets it out past my prostate, but it really seems to require a standing position for success.

Later in the day, let's say at school, if I have to poop, I don't have to pee again afterwards. Odd.

To the person talking about the girlfriend/child birth deal. Yes it is common for women to shit while giving birth. Just think, if you're trying to push a 7 pound object out of the front the muscles in the back more than likely aren't gonna be strong enough to hold in whatever's in there when there's that much force being exerted. It's really not that big a deal though, just be sure that the area is well padded down before a home birth. o-o

ant1ph0n's picture

eh it's late at night and i only read the line about peeing and pooping at once.

i just read recently the muscle(s) associated with peeing and pooping relax when either is happening so that's why urination is almost always accompanied by flatulence and urination during defecation.

just some insight, and it was probably already said in the article which i will read when i wake up tomorrow morning/in a couple of hours...

Can't speak for the vaginas there Cheeky, but if I don't hold down my dick, I often get a wierd, warm, wet feeling on the back of my legs.

This may be a problem that only effects those who, like me, must use a urinary catheter to completely empty their bladder. I must self-cath before a bowel movement or I will empty my bladder at the same time. This was never a problem before I had to start using a catheter.

woah. and here I thought no one else had this problem.

o.O I had no idea guys had to "tuck it in" or whatever. lol I guess that explains why my brother would always leave piss stains on the floor or something when we were younger :( I guess he had to figure it out the hard way. lol he got yelled at so bad.

I find it's possible to not pee when pooping if you pee first - but a little usually comes out anyway... but it's not really an issue what with me being a girl and my junk aiming down anyway.

Hopefully given the subject matter here anybody reading is beyond being offended...

When I use a dildo to anally masturbate, if my bladder isn't empty it soon becomes empty. In fact even when I think it's empty often I find out it's possible for it to be more empty.
So yes, you can't take a shit without peeing.

I almost always pee while pooping. It doesn't even feel like I have to pee sometimes but almost always end up peeing.

Anonymous Coward's picture

im surprised no one commented on this...

"And, speaking of front-to-back, except for fastidiousness, why is back-to-front a problem? Ever changed (or been present) when a baby girl's diaper is changed? Often poop from coccyx to front of vulva (should I be using a more euphemistic, less anatomical word here?)"

if you wipe back to front, you are transferring the harmful bacteria from the anus to not only the vagina opening but to the opening of the urethra. this can cause some nasty infections, including really serious urinary tract infections or yeast infections. plus, who wants poo smeared all over their girl parts!!

It depends what time of the year it is. At school, I pee and poop at the same time because in most cases, I would have waited 5 or 10 minutes in line for a stool that's clogged and a seat that's dirty. Only a moron would sit down more than once a day. When I'm home, I usually separate the two because I have time on my hands and more privacy. I also separate the two when I'm at my job since I enjoy getting off the floor for a couple of minutes and off my feet. My best friend also works retail and she has to punch-out to take a bathroom break. That would suck!

Alright... I can not be the only one... I better not pee while pooping, unless I have a bucket. Few feelings are worse then squatting for a good poop, and having a certain member hit cold toilet water. I pee before I sit, then let my friend hang over the edge.

I will also pee while I am pooping. I usually have it tucked anyway while I am sitting on the toilet. With that in mind, I might as well. The worst with me is when I am at a urinal peeing, and then I feel a shit coming on , and I have to abruptly stop my pee and find a stall to sit in so I can poop, and I continue my pee once I am seated and pooping.

Jesus H. Christ, you have that small cubicle all to yourself. Just shit, pee, fart, shoot snot rockets at the door, and hock up a good loogie and send it flying at the ceiling. That way, when you are cruising the mall you can be very civilized.

I'm 14 and I agree with Second Thoughts Sue. At places like the mall I've seen mothers alone and mothers with kids by the hand check out the toilet paper supply before they let their young daughter go into a stall and sit down. If there's no toilet paper or very little on the roll, they will take them over to another line. For the simple pee, a stool with a seat and a couple of minutes are all I need. I'm pretty easy to please as long as I get to pee without wetting myself. Wet underwear sucks.
