Why does diarrhea-causing food expedite defecation?

699 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.

I feel like something important being overlooked by most responses at this point is the osmotic effect of certain things in our digestive tract.

In addition to the “eject button” everyone keeps mentioning, certain foods just intrinsically draw large amounts of liquid inside our intestines. As a result, things are thinner, more fluid, and move faster.

This is how many laxatives work, osmotic laxatives. They are just salts that draw water inside the GI tract and promote defecation.

So, depending on why your food is spicy this could be at play. As previous posts mentioned, as things move from Point A to Point B, nutrients are absorbed. But if certain nutrients or other consumed producers cannot be absorbed into our bloodstream, they remain inside the tract and make it to the colon. Here, these things have the sense effect as the osmotic laxative.

Spicy foods heavy in spices (middle eastern foods for example), or other foods with peppers and seeds (Mexican) both have indigestible things in them that will have this effect
