Can constipation cause anxiety?

Right now im feel really anxious, for example i feel like im not able to breathe at times and am not able to travel in a car for long periods of time without feeling like i cant breathe. The only thing I notice though is that i’m somewhat constipated. I’d appreciate any help or advice.

I think – because of the intestinal autointoxication factor – that the influence can flow both ways. Anxiety causing constipation or constiptaion causing anxiety.
How to minimise the risk: high fiber diet, active lifestyle, obeying the call of nature when it comes, and – keeping a food/doodoo diary for yourself (as well as your kids!)
