IBD shares this lack of understanding and heavy handed approach with many other autoimmune diseases. Being in this category is not a good thing. It's not unfair to lump IBD/IBS together; people who have these conditions share a lot of the same issues and struggles.
Never had any test done for SIBO I think. They did a stool test, sigmoidoscopy and found nothing. That is how I ended up being diagnosed with IBS.
Dealing with the medical system and outside advice in general can be very frustrating. Hope you can find a way forward! Good luck!
We don’t fully understand most disease processes, even those for which we have some effective treatments.
I don’t think lumping disparates diseases together simply on the axis of “understanding of disease process” is terribly useful.
IBD is itself a lumping of disparate diseases based on very minimal understanding of disease process, so I'm not sure what your point is.
IBS is a syndrome (the S in the name) which usually implies a constellation of findings, but not a specific disease process. From the name you can know that the disease process hasn’t been clearly elucidated.
