While food or stress can often trigger IBS-D symptoms, there are other possible causes:
There’s a change in the speed of food moving
through your colon.
Your colon contracts (squeezes and releases) in order to remove waste from your body. If contractions are too fast, it can speed up the process and lead to diarrhea.
Your intestines are hypersensitive.
When your intestines are active or stretched, as food moves through them you might feel more pain than is usual. This sensitivity could also lead to changes in digestion speed.
There are communication problems between
your brain and gut.
This can lead to changes in how quickly food moves through your gut, the processes that occur along the way, and the sensations you feel as food is broken down and travels.
