Constipation, Pooping, and Migraines

I was officially diagnosed with migraines about 18 months ago. I keep a journal of my symptoms and migraines to take note of triggers, symptoms, things that help, etc.

I have a possibly odd question for all of you. Have you noticed any connections between constipation, finally going #2, and getting a little relief from your symptoms?

It doesn’t happen every time, but sometimes my postdrome symptoms improve very soon after I’m no longer constipated.

I can’t figure out why my gut would affect my head like that. Maybe it’s a coincidence, but I’m curious to hear if anyone else has noticed this sort of thing.
