Anxiety and IBS

So my doctor claims that I have IBS due to anxiety. But how can one be in a deep sleep and wake up with severe cramping and Diarhhea. It's not like I was having a nightmare. I was sleeping! How can one have anxiety while sleeping. I don't see how anxiety/stress/IBS can cause a person to feel this at a time when we aren't even anxious!

But diarrhea and cramping?

Anxiety during sleep is quite common so naturally your body is reacting to it. Also considering that digestive system is directly in contact with brain, they get effected by anxiety first. This is very reasonable.

I hope you feel better soon
