Does IBS lead to ibd (crohn's or ulcerative colitis)?

No, but. No, but some patients diagnosed with ibs will eventually be diagnosed with ibd. This is not because ibs becomes ibd, but that early onset ibd may present the same as ibs and then eventual will progress into a clinical picture in which ibd may be diagnosed.
No. Irritable bowel syndrome (ibs) is a functional disorder of the intestine which can causing cramping pain and changes in bowel habits. Inflammatory bowel disease is an autoimmune disease leading to severe inflammation of the intestine, often requiring surgery. Comparing these two diseases is like comparing a headache to a brain tumor.
Causativefactor same. Ibs does not lead to ibd - interesting new observations that suggest that some of the factors causing IBS and ibd (crohn's and colitis) may be similar, involving the intestinal immune system and bacteria within the intestine. The great differences between IBS and ibd makes it unlikely that they are caused by identical processes.
