Why does diarrhea-causing food expedite defecation?

695 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.

Under normal circumstances food travels from your stomach into your intestines and is slowly pushed through by muscle contraction and relaxation. As it enters the intestines it is a watery mess and as it slowly passes through water and nutrients are absorbed. So if you have very very slow digestion, nearly all the water is absorbed and you have rock hard poops. If you have a very fast system, you poops are much softer.

In the case of diarrhea, an emergency signal is sounded and those muscles that are squeezing the material through all relax causing an open and unrestricted pipe to the anus. The material flows through very quickly without losing much water. The result is the contents of your intestines comes out quickly and still full of water, including what was already in there, which might be a little less full of water.

The 2-5 day thing that always comes up is BS right? I always see mixed things but even websites say when you do the corn test you should see it in 1-2 days so where does the 2-5 come from? I always see my food in my poop the next day.

2-5 days? Tell that to my system. 24 hours tops. Sometimes 12. Alternating tracer rounds – corn, blueberries, spicy food
