Why Does Your Stomach Rumble When You Are Not Hungry?

at 6:00

From the episode: The surprisingly charming science of your gut | Giulia Enders

Answer

When you hear your stomach make noises, that is not because you are hungry. The small intestine takes time in-between digestion to clean itself, resulting in those 8 meters of gut to be very clean and hardly smell like anything. In order to achieve this cleanliness, the strong muscles move everything forward, and that is what sometimes makes a rumbling sound.
