ELI5: How come when my stomach hurts, it feels like a wave of "I gotta s**t right now" and few moments later it's as if nothing happened?

Imagine your bowels as a ship.

Normally, a bit of water will get into the ship and it's pumped out without any effort (the large intestines/colon reclaims the water from the food we eat). However, if a huge amount of water gets into the ship (from disease or the body's response to flush your digestive tract), it can create a bit of panic for everyone on the ship.

Yet, if the water pumps are fully capable of pumping out that water, then the feeling of panic will subside and things will go back to normal.
