In the evenings, I sometimes flush bright red. Since this could lead to rosacea, I try to minimize things that might cause it, but I've yet to figure out a real trigger for what does it.
I have IBS too. It waxes and wanes depending on my stress levels, regardless of coping with the stress. I eat yogurt on an almost-daily basis and that seems to help, as does a high-fiber diet. But even so, some months it seems like I've gone through a cycle of either explosive diarrhea or constipation. I carry wet wipes with me at all times (Wet Ones Fresh'n'Flush, highly recommended) because I will inevitably have a loose bowel movement somewhere that isn't my home. I got over the fear of pooping in public toilets a long time ago. The IBS also sometimes keeps me home sick; some professors (my stats prof) really don't like it when you get up 10 times during a lecture. That is when it is really inconvenient and I will take a loperamide, though that usually just leads to the constipation side of the cycle. Ugh. But yes, I know every bathroom on campus intimately, it seems.
And ng, thanks for the info about dumping syndrome. It's interesting to see it's connected with hypoglycemia, as I'm hypoglycemic too. THAT one is really fun, though it only rears its head on days when I am not careful about eating regularly. I get super cranky and stupid. I try to carry a snack with me everywhere so it doesn't happen, but there are sometimes when I am caught without a snack.
