Why does diarrhea-causing food expedite defecation?

693 views

So after googling, the normal food you eat is supposed to take 2-5 days to go through digesting all the way to defecation.

I know eating spicy noodles will give me diarrhea but I still eat maybe once a couple months because I love them so much.

It takes only 5-6 hours before I get abdominal pains and have to relieve it at toilet.

So how does this spicy noodles skip everything in my system and kinda pushes in front of the queue to leave the body, it just doesnt make sense?

Edit: thanks for all the answers guys. I didn’t know the body could do that. It really is amazing. And now I feel kinda stupid for not figuring this out for so long.

So now I guess eating spicy noodles doesn’t only give me an unpleasant trip to the toilet but it also gets rid of all the nutrients my body was absorbing from my previous meals.

5 days? 24 hours max.

The top answer here is the best explanation of this I’ve ever seen: https://reddit.com/r/explainlikeimfive/s/vyhPOtkBpV

Your brain and gut are pretty well connected, and your brain has a big red button that says “FLUSH SYSTEM.” When your gut tells the brain that it found something bad in your food, your brain slams that red button, and your gut flushes everything out with water.

This is one reason why you need to drink a lot of fluids when you have diarrhea. You lose a lot of water

Fascinating. Does this ’emergency flush’ also explain why long-term diarrhea is so debilitating? Your body is losing loads of water, but also not getting enough nutrition from your food since it’s just being lubed up and shot out the backdoor too fast?

I had this problem, and turned out it was the sesame oil they used, and not the noodles or spices.

Diarrhea basically means that your food moves through your intestines too quickly, so your intestines don’t have time to absorb all the water and nutrients from it.

Interestingly, the common anti-diarrheal medication Loperamide (Imodium) is an opioid that slows down your intestines. It bonds with the opioid receptors in your intestines, slowing their contractions and allowing food to travel more slowly so that water and nutrients are absorbed.

I don’t get diarrhea when I eat spciy noodles, anyone else?

Okay so then if someone is constipated, then gets diarrhea, are they getting rid of whatever has been ‘stuck’ in the intestines ? Is this how flushes work? Wouldn’t nobody suffer from constipation then? And how would volume affect any of this? Cause I’ve had diarrhea before, but it’s never felt like I have shit ‘all my guts out’.

It takes 5-6 hours before you get inklings of diarrhea? I know in about 30 minutes if something is being rejected.

2-5 days? That sounds incredibly long. Id feel awful. Myself, never more than 2 days. Usually 36 hours.
