Inflammatory Bowel syndrome ALSO falls under the IBD umbrella. Many times IBS is a precursor to colitis, which generally happens before Crohn's Disease.

I'm confused, if IBS falls under the IBD umbrella then what's the difference?
I thought the absense of blood in the stool, weight loss, and fever is what separates IBS from IBD. And those symptoms are the result of inflammation and ulcers, right? So, I assume that the inflammation in IBS is not as severe as Crohn's?
