I KNOW that SOME people with fibro have digestive issues. Unfortunately I am one of them and have had Crohn's all of my life.....before fibro, I might add. BUT this is a digestive issue and we have an IBS, Celiac Disease, Crohn's Disease, and Allergy forums that discuss this. We aren't repeating this over and over again here.
As far as leaky gut goes, they think it has something to do with the lining of the intestines...a digestive issue not a fibro issue. These digestive issues co-exist with fibro but don't cause fibro. If someone is really having digestive issues they need to go to the appropriate forum.
