Poopy Pants asks:

Why is poop so stinky? I mean... food doesnt smell like that, so why does poop? Also, why do some people's poop smell worse than others?

(((Poonurse: I thought about answering this question that it was due to bacteria in your stomach. And then I thought that when you are first born, you don't have that bacteria, which is why babies poop doesn't smell. And then I remembered that baby poop is just horrible. Do you have any insight?)))

---- Dave





Dear Poopy Pants,

You are right on about the bacteria. The bacteria inside of the feces is what makes them smell so bad. Specifically, the bacteria produce various compounds and gases that lead to the infamous smell of feces. Just in case you were wondering, you can get very sick by eating feces because it contains so many types of bacteria and other harmful substances such as parasites. So I wouldn't suggest adding poop to your diet any time soon.

Poop will vary in smell depending on the type of foods and drinks that you consume. Generally speaking, feces will smell worse if you consume foods or liquids with many artificial flavors or chemicals in them. The bad smell of feces will usually be reduced by eating more natural foods that do not contain any artificial flavors or chemicals. Also, the poop of meat eaters usually smells worse than that of vegans.

Incidently, I change about 10,000 diapers a day at work. The baby's first poop is called meconium. While tarry, black, sticky and yucky to look at, it does NOT STINK.

Please be advised that I am only a Poonurse. I am NOT a medical doctor. Any advice I give should be taken moderate skepticism. Please consult a REAL medical doctor if you feel you have a serious medical condition.

-- Poonurse

Poonurse is an RN with 25 years experience in labor and delivery. Her qualifications include seeing a lot of poop, and owning a computer. Also, she works in Michigan, which she calls the asshole of the universe, so that's another bit of credibility.

Got a question for her?

I think tightening ones belt too tight might be a mitigating factor in turd stink. When one factors the amount of formentation in the gut, it might be reasonable to deduct that a stationary fetal poo, like hops in a corked beer keg, indeed gains strength with time.

As I went off on a pootangent earlier, I should actually give my own opinion of what makes some shits smell worse than others. IMHO, it's the time it spends festering in the bowels.

Pooing, as we all pretty much agree, is the most fun one can have fully clothed. It feels immensely satisfying, is attractive to look at and a lovely, fibrous, spongey stool smells pretty good too. It's kinda like that farmyard aroma, whereby it quite obviously smells of shite, but it's not an altogether unpleasant odour. A healthy smell, although not, perhaps, a fragrence that Hugo Boss would wish to replicate for their next perfume.

As a man who enriches his life by shitting an average 4 times per diem, I seldom have the opportunity or inclination to 'bake' a poo. If I feel the least tug in my colon, I like to get it out asap and the idea of hanging onto it until a more convenient time, horrifies me. It's such a fantastic feeling, giving birth to that beautiful brown baby, that shitting, for me, is an opportunity for recreation, and I never miss the chance of having one. As such, things move pretty quickly through my system and by and large, the poo that comes out of my arse is good and healthy - usually a 4 on the Bristol Scale - and smells of poo, obviously, but it isn't a foul stench.

However, I said it horrifies me to hold it in, and it does, because to back one up and bake it for a few hours, seriously fucks my guts up. For a start, my natural rhythm is put out of kilter, which is bloody annoying, but it's also bloody uncomfortable. My arse just isn't used to holding it back, so my belly hurts, and when my overcooked brown trout finally gets a chance to kiss the water, it's changed consistency, so that when it makes it's dive, it's firmer, takes a second or so longer than it should to emerge fully, and subsequently, one's nipsy messily crimps off the end like an ineptly wielded cigar-cutter, instead of finishing it off neatly, and then coughs out the stump. It's acceptable of course, to poo in several sections, but when one is labouring to lay a compacted log and has almost succeeded in pumping out a single glorious length of gutpaste, but then due to some infernal involuntary reflex it's broken into two...well, it's the wrong side of enough and I don't care for it above half! But that's beside the point, which is that these poops, the ones that have been baked for a while, well they stink like a Cairo sewer. I assume that the bacteria which cause the aroma are multiplying more rapidly when they have been fermenting in the bowel, and the longer the fudge stays packed in the poo-pocket, the worse the aroma gets when it emerges.

So in essence, if your poo really smells bad, start going at the first sign of pressure down there and don't let it cook.

By the way, I still await an answer to how blind people know they they've wiped properly. But I suppose I'll never know.

Tally ho!

Now that I'm thinking about it... maybe the guide dog gets involved. After all, they can't leave other dogs arses alone, so perhaps cleansing Master's ringpiece is part of the training, helping also in adding variety to their diet.

I think we should be told.

Poopcurious's picture

Poo-poo's smell is partially a result of the time each bolus spends in the sinuous slide of stink, but also is a result of the horrible imbalance of bacteria in our colons. The modern diet, filled with processed foods, booze, sugars, as well as non-dietary things such as smoking, deoderants, and basically any chemical that you expose yourself to kill off the good bacteria, yielding an overpopulation of bad bacteria that stinks. To combat this, one can only do his best to eat high-fiber, organic foods and supplement with megadoses of PROBIOTICS, which should help to level out your intestinal bacteria and not only clean up the smell a bit, but improve your overall health. Also, I've found that protein is the worst shit-stinkifier...especially protein milkshakes and tunafish.

EScumdiddy, blind people wipe just like anybody else. I don't need my eyes to wipe. It could be pitch black and I would have more trouble finding the toilet than I would my butt. I poo in nightlight lite in the middle of the night every nite. I don't turn the light on for wiping. I could blind fold yourself to find out how blind people wipe. I'm sure chief and pD will have a wisecrack coming for you.

I haven't ever seen a white asshole on a baby. I have seen pink and red ones and brown ones on dark skinned babies. Basically it is a skin pigment thing the darker your skin the darker your asshle is. I think it is the same with areolas(the part around a nipple).

This is a great page. I have been trying to find a way to keep ass-smell away (not poo-smell, but the sweaty ass odor that comes with a hard day at work). I've started to enjoy the sharp odor of an adult ass a bit. Am I alone in this?

Also -- have always been massively entertained by the smell of poop and heavy farts. Carrots and whole milk definitely add to the stink of a baked loaf.

Gay poo, you sound like a poopreporter so why don't you register? That sharp ass smell is genetic. Some have it sharp and some asses have it mild. I'm not keen on sharp ass smells myself but Bilgepump probably likes it.

You guys are so funny (and some very intelligent)! Everytime I eat garlic, in a few hours my poop will smell like garlic, it will burn a little bit, and is smushy but not runny. Is this normal, or do I have a sensitivity to garlic?

The garlic smell usually oozes out of your pores, especially when you sweat. So does curry powder. Don't believe me? Just go into any NJ gas station and take a whiff of the attendant. It won't be gasoline.

I have actually never thought that garlic breath was offensive. The bad breathe that bothers me is that rank smell that comes from the mouth of those with rotten teeth or with little pieces of meat trapped and fermenting away between their choppers.

In my opinion all shit stinks, except mine of course, and garlic makes it no worse. Actually a nice garlic and onion fart, from my vent only, has a charming and playful aroma. I am willing to mail out samples for the curious if Postman is OK with delivering them.

This time it was olives with garlic in them...about 5 cloves? I tasted the garlic before I decided to chow down cuz I've had this "problem" before, and the garlic was not "hot." Well...it took me 3 days to eat the whole jar, maybe I just over-did it with the garlic. Thanks you guys, you are so funny! PR.com should have it's own stand-up comedy show!

I think it all has to do with food combinations. By example, take cheap beer (alot of it) and add some nasty combination of white castles, onion chips and wendy's chili and there will be no wonder why it stinks.

Human poop is similar to natural gas. A smell is added to natural gas so that the dangerous presence of gas can be detected. Nature makes poop stink so that we do not step in it or God forbid, consider eating it.

I would like to know why my poop smells like cat poop. I has smelled this way since I had gallbladder removal surgery and had my last hernia surgery and they put in a patch in my stomach... Pleas help!!!

MOSSYDOG's picture

I just stumbled on this thread after typing "when I fart hot, they stink sweet" Into Google. It's a bumper sticker I made to put on the bumper of someone who pissed me off once.

"Ahem" -- General poo and fart lore: 1)Farts stink because they are comprised of gaseous anal oxide.

2)When on the road (or if you are someone who poos), rub a little white petrolatum, or similar substance, on yer poo-hole when you start your day. Poo-poo will slide out easily all day, and the TP will be *clean*. Also, if you enjoy anal sex, you''ll always be ready!!!

3) RE: Ass Munchies, my first Ex wife had the same problem, but she only de-feceated every other day or 3 (she was from Boston and so was, umm anal retentive) She called it "Big Doody" cause it was HUGE, and her butt always smelled .. too bad for her cause I really like to 69 and when in that position your nose is, literally, in her butt.

4)Once I worked at this great restaurant that served roasted garlic with home baked (fantastic) bread at every table. Needless to say, I ate A LOT of garlic, and although it didn't leak out of my pores (I'm a Dago) my farts were very airy and smelled like roasted garlic, but no poo smell at all.

5 2 Tbsp rice bran daily (if you can still find it.-- It tastes just like slightly sweet beach sand)gives the perfect poo - not too hard, not too soft, floats, not much stench,relieves both too hard and too soft stools. I have shared this tip with many many humans over the desperate, meaningless years of the sad and unholy stench that is my worthless existence, and the outcome (heeheeheeheeheeheheheheeheeehehheee) has always been the same. Stay strong my fellow poo-ers and evacuate proudly. Poo will never let you down!.......Mossydog

I definitely think it's all about the food/drink you consume. I have gone out and gotten pissed on beer, tequila, red wine and more tequila, the next day when i have a hangover shit, my shit is dark like the black plague, and it smells totally obnoxious, like the sweat from a baboons balls. Usually i have a quite a good relationship with the smells of my farts and craps (nothing smells as good as your own brand) but, not even I can handle the morbid stench from my bowels after I have been drinking heavily.
