For years I swore stress had nothing to do with my flares. Then I started observing myself and my reactions in different situations. (I posted here officially "eating my words" about
a year ago!
I am known professionally as being "very good in a crisis" - and it seems that the "crisis" type of stress doesn't bother my UC. But long, drawn out little stressors..... maybe things I'm not in control of....? do tend to bring on symptoms. I'm still trying to figure this out.
I often flare while at my in-laws' for a week (we could make a lot of jokes - !! but in fact they're great folks) and this past year I tried to observe my stress state a lot, and found that I got that "tied in knots" feeling when I was acting as go-between, smoothing out the various family dynamics. So... I caught myself, did some deep-breathing -type "meditation moments" and I remained healthy...!
I talked with my GI some about
this; I figure that the stress thing releases chemicals that are inflammatory.
Re. the delayed response some have mentioned - I remember reading 15 years ago about
some study which indicated that often a flare happened 6 months after a stressor - so I guess the "flare afterward the stress" is pretty common!
