How it works

- This stimulant action can speed up contractions in your gut. Think of it like a gentle nudge.
- Your intestines start to move things along faster. This is part of the gastrocolic reflex.
- Coffee can also trigger the release of gastrin. This hormone helps digestion along.
- For some, the cold temperature of iced coffee might add a little extra kick. It’s like a shock to the system.
- The acidity of coffee, even iced, can irritate some stomachs. This might lead to quicker transit.

- The speed-up means less time for your body to absorb water. This can make stool softer.
- So, a trip to the bathroom might be in your near future. It’s a common coffee experience.
- It’s all about how your body reacts to the caffeine and the brew itself.

Common misconceptions
