You have to find your own solution for IBS as doctors don't seem interested. I have had massive imporvement in symptoms since cutting out anything that contains wheat. I also have a feeling that dairy products have some bad effect but one thing at a time!
I too suffer from anemia
and the indigestion
has definitely got worse since starting iron supplements
. I have had the IBS for years without being anemic so in my case it's not the anemia causing the IBS.
Most people are able to control it with diet to some extent - yes stress
can cause flare ups regardless of your diet but I do not believe that it is purely down to that - as you say case in point it can't be when so many people suffer even when not stressed.
Good luck with it, hope you get to a point where it isn't so difficult for you.
