Luckily this effect only lasts a few days for me but it's made me wonder if our bodies find ways around malfunctioning and then can't adjust quickly enough if the malfunction is reduced or removed.
Really I couldn't have asked for a better problem to deal with. The correlation between mind/gut health is so instantaneous and powerful, my child brain got Pavlovian-conditioned to deal with mental stress. I couldn't just dissociate from mental pain, I really had to understand and deal with causes of stress in a healthy way, otherwise I would be forced to the floor in the fetal position from all the cramps. Platitudes about always listening to your gut are funny, taken both literally and figuratively that's my life!
When I was a kid I used hate using school toilets. And I was a highly anxious kid which would present as stomach butterflies. I dealt with constipation as a kid, which further made me nervous because I'd experience it AT school and be too afraid to sit down a while at school.
Fast forward 20 years, the most stressful time of my life (moving cities, dealing with depression, mom got cancer, ...) and I developed IBS-C. My intestines don't move thing along, need to stimulate with drugs. Unfortunately it hasn't gone away.
Different people with different biology react differently but my bodily reaction to stress happened to be a lot like the one in the video.
