What are L cells of the intestine?

The L cells of the intestine are tiny helpers that tell your body when to stop eating.

Imagine you're eating a big bowl of ice cream, it's so good, you don't want to stop! But after a while, your tummy gets full. That’s when the L cells, which live in the wall of your intestine, step in. They send out a message that says, “We’re full now!” This helps your body know when to stop eating.

Think of the L cells like little sensors on a seesaw. When food moves through your intestine, these sensors feel the pressure and the kind of food you're eating. Once they detect enough food, they send a signal to your brain, just like how a seesaw tells you when it’s balanced.

This signal makes you feel full, so you stop eating. It's like having a friend who nudges you and says, “Okay, that was enough!”

Without L cells, we might eat way too much and never know when to stop, just like how you might keep adding scoops of ice cream without realizing your bowl is overflowing!
