What Causes ‘Hunger Pangs’ When We’re Hungry?

Hunger pangs are when your stomach tells you it’s empty. When your body doesn’t have food, your stomach starts to contract and stretch in a rhythm that feels like it's 'growingl'. This makes you feel hungry, almost like it’s asking for help.

Your stomach is full of gas and liquid when you eat, but as time passes, everything leaves. The empty space stretches the walls of your stomach, which sends signals to your brain that say, 'I need food!'

It's like when you're sitting in a chair after eating, then stand up, suddenly you feel wobbly because your body is used to being full.
