Why is ingesting fecal matter dangerous even though its just stuff from your body?
In: Biology
I’d like to add to the other answers here that your own poop is much less dangerous than other people’s poop. I definitely don’t recommend eating anyone’s feces, but your own has bacteria that you already have in your gut, whereas ingesting (other people’s) fecal bacteria is one of the most effective ways to get many diseases from them. That’s how cholera and hepatitis A spread, for example. You can’t give these diseases to yourself.
But still, like other people have said, your poop is made of stuff that your body wants to get rid of, so at best, eating it is making your body go through the same process again. At worst, it can poison you, because you’re getting too much waste material in you at once.
Once you have the forbidden paste, you’ll never want to eat anything else and raise risk of starvation.
Colon have slightly different environment that stomach and duodenum. Ph, hcl, h concentrations etc. So poop comes with bacteria that otherwise won’t be in the upper GI like faecalis enterobacter etc. and if you eat it, that bacteria will colonized and more likely infected the stomach making you sick. Hep A can be present in fecal matter and spread through water once it is contaminated with feces. In 3rd world country it is a big problem, especially in schools we’re students eat street food outside that was not prepared under standard practices.
I think most answers here is wrong. As always people are just guessing. I am not a fecal expert , but just have an interest in gut flora.
1. Fecal matter have not been inside the body. Some stuff is excreted from the body to help digest / absorb the food, but ELI5: fecal matter is food that was not absorbed.
2. When you can get sick by eating fecal contaminated food it is due to getting bacteria that causes a stomach sickness . Eating some of your own gut flora will not make you sick.
Your own really isn’t unsafe. You aren’t going to infect yourself with something you already have (except some parasites, they have complicated life cycles, so re-infection can be a problem). It isn’t toxic. It’s just useless – you’ve already taken all the nutrition out of it.
Urine is mildly toxic – it contains diluted toxins removed by your kidneys, but not enough to be actively poisonous. Again, it’s mostly just useless – if you drink it to combat dehydration your body will have to use all that water to remove the toxins you’ve ingested alongside, so it’s not much help at all. It doesn’t have any bacteria, though, so it won’t cause infection.
Other people’s faecal matter is extremely unsafe, though. It’s full of bacteria, some of them harmful. Lots of different ailments spread through fecal contamination: cholera, dysentery, typhoid, almost all parasites. That’s why the smell is so disgusting – it’s evolved reaction that protects us from infection.
It’s your body’s garbage. Would you eat trash from a dumpster?
Uh, cause a whole lot of bacteria that are not produced by your body hitched a ride on your poop. These bugs may not cause disease or infection in your intestines but they can in your mouth, your blood, or on your skin. And don’t get me started about other people’s poop.
First thing is that when you’re talking about contamination, the main issue isn’t your own stuff. Your own stuff can get you sick, but I’m more worried about someone else with something quite nasty to share through poor hand washing. We take sanitation for granted, but each and everyone of us is one bad salad away from shitting blood in a hospital bed until we die.
Look up E. coli 157 and the news behind it for more info. .A major US burger chain had contaminated beef kill some folks and then try to cover it up. Think about that next time you see some instagram incel licking taco shells for social media.
Now to finish the first part of your question, your own bacteria can hurt.you because your stomach cannot handle bacteria from your butt. Different environment, different amount if defense. The majority of your immune system is in your gut, btw.
