What is it that makes feces smell bad? This is a serious question.?
405675
The distinctive odor of feces is due to bacterial action. Bacteria produce compounds such as indole, skatole, and thiols (sulfur containing compounds), as well as the inorganic gas hydrogen sulfide. These are the same compounds that are responsible for the odor of flatulence. Consumption of foods with spices may result in the spices being undigested and adding to the odor of feces. Certain commercial products exist that can reduce the odor of feces.

Smelling salts   (ammonium carbonate)\nbasically it's a really stinky ammonia smell that's released when you break this little cloth-covered ampule.

ROFL!  Look around as if you're looking for where the horrendous odor could be coming from.  I'd tell you more, but just watch for me in the check out line.  You can learn my secrets there.\n\nOh come on people don't take it so seriously.  You flatulate too.  Maybe not in public, but you do it somewhere.

Because fecal matter is really not good for you to breath it can in fact make a person sick if they are around it too much, the poo is all the food that one has ingested and it is the bi-product (the left over stuff that your body doesn't need). Some people may digest differently then you and you are used to the smell of your own poo (which stinks too), perhaps some are proud of their own stinky poo and want to share it's aroma by not flushing, or spraying and by leaving the bathroom door wide open this is considered rude however it is usually fairly funny.

Why does poop stink?\n    Poop stinks as a result of the products of bacterial action. Bacteria produce smelly, sulfur- or nitrogen-rich organic compounds such as indole, skatole, and mercaptans, and the inorganic gas hydrogen sulfide. These are the same compounds that give farts their odor. \nWhy is poop brown?\n    The color comes mainly from bilirubin, a pigment that arises from the breakdown of red blood cells in the liver and bone marrow. The actual metabolic pathway of bilirubin and its byproducts in the body is very complicated, so we will simply say that a lot of it ends up in the intestine, where it is further modified by bacterial action. But the color itself comes from iron. Iron in hemoglobin in red blood cells gives blood its red color, and iron in the waste product bilirubin gives rise to its brown color. \nWhat other colors of poop are possible?\n    Poop is mostly shades of brown or yellow, but other colors can arise under certain circumstances. For example, someone with a bleeding ulcer might have tarry black poop from the presence of partially digested blood. Bleeding in the intestine, from an anal fissure or split, for example, can stain the poop red. Bloody poop can also be a sign of colon cancer, so you should get it checked out by a doctor if you see blood in your stool. Some illnesses in babies gives them green or even blue-green poop. But another source of blue poop in children is more innocent: it can come from eating a concentrated source of blue food coloring such as ice cream. Intense red food coloring can produce bright red poop. Sometimes brightly colored foods pass through the gut almost unchanged, and the turd may be speckled with bright red fragments such as pimentos, or bright yellow kernels of corn. \n    Poop can also be stained red if you eat beets, according to Ellen. \n    One can experience white poop after consuming a barium milkshake for the purposes of getting an x-ray of the upper gastrointestinal tract. \nWhat is the cause of yellow poop?\n    According to Michael F., one cause of this is Gilbert's Syndrome. "I have a benign condition known as Gilbert's Syndrome. It affects quite a few people, males mostly, in their teens+. It is a deficiency in the liver where red blood cells are broken down. I was informed when this was diagnosed that the broken down blood cells is what gives poop a lot of its color. People with Gilbert's Syndrome don't process as many blood cells - or not as fast - and their poop tends to be pale brown or yellow from the lower quantity of discarded red blood cell matter. This is especially true if there is less matter in your intestines (i.e., on a diet - as I have noticed) to remove the excess blood cells. Very frightening until you determine what is causing it. Gilbert's is a totally benign thing that doesn't harm anyone, although when a person is sick they can turn yellowish as if jaundiced, but it is not jaundice." \n    Another cause of yellow poop is a giardia infection. Giardia are tiny Protozoan parasites that can invade the intestines and result in severe yellow diarrhea. It is a dangerous and contagious affliction that doctors are obligated to report to the Center for Disease Control. \nWhat is the cause of green poop?\n    (Question submitted by ap, CrAzYMiC98 and several others) \n    I have consulted with a doctor, a physiologist and a microbiologist on this question, and the following summarizes their answers: \n    Healthy people can have green poop if they eat a diet rich in leafy green vegetables, or if they consume large quantities of food coloring (in ice cream, cake frosting etc.). \n    Green poop can also be caused by excess iron in the diet, from dietary supplements, for example. If the body does not absorb all the iron consumed, the iron may stain the poop green, the color of iron (II) salts. Ordinarily, the green color may be masked by the normal brown poop color, but if digestion is thrown off by illness

Many diseases cause bad smells; infections, gum disease, but most often, the source is usually the mouth, underarms, genital area, or feet.  \n\nMost of these odors are avoided by  good hygiene: bathing daily, using shampoo and soap; brushing teeth twice per day, seeing a dentist regularly, flossing and using mouthwash; and laundering clothes regularly.  \n\nMany people fail to do these simple things. \n\nIf it's bad breath, allergies that dry the mouth and cause mouth breathing can lead to chronic bad breath. Smoking and bad tooth care lead to bad breath and abscesses of the gums, more bad smells. Genital infections and incontinence lead to bad smells. There are all kinds of bad smells.\n\nA "dirty laundry" greasy oily smell is usually due to failure to wash clothes regularly.\n\nA dirty hair smell accompanies greasy hair.\n\nA putrid (dead animal-like) sweetly-sick stench is often an infection. \n\nAn acrid (sour-bitter-metallic) smell is usually rank sweat from lack of wearing deodorant and showering regularly. \n\nSome people grow up rather neglected and never learn about handwashing, regular bathing or hygiene. Don't assume she knows about this.

Human sense of smell is designed to identify things which are bad for you so you can keep away from them/not eat them/not smell them, in order to avoid disease.\n\nEveryone's gut contains bacteria - often a specific combination of bacteria that your own gut has built up for itself and finds useful in digesting food and fending off 'alien' bacteria.  \n\nEssentially this means that your nose is smelling someone else's gut bacteria and recognises them as alien and not good were you to ingest them for any reason. \n\nSo it's just your nose's way of telling you that these bacteria are bad and not to get too close - that's why some smells are 'bad' and some are not.

The smell you are finding is due to moisture and warm conditions that allow bacteria to grow and multiply. Yes bacteria. The smell comes from the "output" of this bacteria as it feeds. The same thing is responsible for underarm odor.\n\nYes, this could be bad if it is not taken care of. First it is generally unhealthy to be covered in too much bacteria anywhere on your body (though you will always have some so don't worry). The area in question could become sore, chaff, and ever get infected. Luckily the fix is simple, wash it every day in the shower.

does this have anything to do with your other question about laxatives?\n\nSeriously, you seem to have a fascination with toilet issues.

Pus stinks because it is filled with dead bacteria. The dead bacteria give off gas as they decompose.

Interesting question.  I'd suggest hydrogen sulfide (rotten eggs), putrescine, and cadaverine.  Any small (say, 1-5 carbon) alkyl mercaptan or thiol smells pretty dang bad.  \n\nIf the army were to go to all the trouble to weaponize something that smells bad, they'd rather kill you than make you vomit.  Usually.

It depends, if it is really bad, it can be caused by an infection and you should see a doctor. But if it is just more intense, then it can be caused by the food you use to take. Anyway, that smell is not bad, it is a natural one.

Rotten egg smell indicates hydrogen sulfite production...protein that is being converted anerobically....Flush it with bleach and begin again.
