How come I have to poop right after eating?
It's a skill that makes constipated people envious
But in reality, being too regular can also be troublesome
Going to the bathroom in the middle of a meal
And coming back to find your plate taken away
From a young age, we often hear
"You poop right after eating, eating wasted"
Why do we poop right after eating?
Is it an illness? Short intestines? Straight rectum?
Is the food wasted?
Pooping right after eating is gastric colonic reflex
Many people believe that pooping after eating
Is because the food you eat goes smoothly all the way
The meal you ate quickly comes out
Actually, that's not the case at all!
When the food enters your mouth
Your body starts a complex mechanism-
Gastric colonic reflex
After several shifts and moves
Poop that comes out ????
Is not the food you just ate
Let's take a look at this
wonderful process together
The food you eat first goes to your stomach
This is the number one storage room
After the stomach is full, it signals the intestines behind
The small intestines are the key absorption workshop
After a series of physical squeezing and chemical assault
Most of the nutrients from the food enter the body through the small intestines
Receiving the signal from the stomach
The small intestines quickly continue to digest and absorb the previous food
Then, it commands the large intestines to clean up the space and prepare for loading
The large intestines are divided into the colon and rectum
Originally, they slowly pushed forward the food residue
While absorbing some water
Receiving the notice to vacate space for loading
Immediately starts moving quickly
With the rapid movement of the large intestines
Food residue that hasn't fully absorbed the water
Arrives at the anus
A smooth and lubricated bowel movement is produced
The full stomach ultimately affects the rapid movement and defecation of the large intestines
This is called gastric colonic reflex
What comes out after eating is ????
It's not the meal you just ate
But the bowel movement that was already in the large intestine
And has already completed digestion and absorption, ready to be excreted
Eating
Just brings them out earlier
The existence of the gastric colonic reflex
Makes most people feel the need to poop after a meal
But the degree varies
Many people who poop right after eating
Are actually more sensitive to the gastric colonic reflex
The urge to poop is stronger
Gastric colonic reflex is the wisdom of survival
Although "pooping right after eating" can be a bit annoying
Our ancestors didn't think so
For primitive humans in a harsh environment
Gastric colonic reflex perfectly matched the jungle survival rules
They solved two primal needs at once
Firstly, it maximized the use of body organs
By quickly emptying the digestive tract space after eating
To ensure efficient use of food
Secondly, it concentrated activities like eating and pooping
To minimize wasting time during critical hunting or escaping moments
Many animals also have the gastric colonic reflex
Eating makes them more likely to poop
If you don't believe it, just look at your cat
As it developed to today
Humans can "poop and slack off" during work hours
No longer pursuing efficient gastric colonic reflex
They found their new value-
Promoting bowel movements
Diet changes, reduced physical activity
Made bowel movements difficult for humans
The "gastric colonic reflex" can drive the large intestines to move quickly
It is a rare defecation accelerator
For people who suffer from constipation
Pooping right after eating
