The gut issues occur due to the relationship of Fibromyalgia with the immune and nervous systems. Besides that a lot of illnesses are now linked to the gut - even things like eczema and psoriasis. Fix the gut and these things have a remarkable improvement or disappear altogether

Both are connected to immune system. Probiotics and digestive enzymes help ibs n help u feel better overall

I think it's a case of if you have Fibromyalgia then you usually have IBS but everyone with IBS doesn't have Fibromyalgia. When my rheum diagnosed one thing she took note of from my PCP is my that I had a diagnosis of IBS.
