Tummy Troubles After Fainting

Unfortunately yes. POTS can cause digestive issues. If I have a day with lots of flair ups, later or the next day I'm having to run to the bathroom.

I think it happens because it’s similar to a visceral reaction if that makes sense

I (thankfully) don't generally pass out but every time I'm flaring up I also get horrible diarrhea. Diagnosed with IBS before anybody even thought I might have POTS
