Hi Babsey,
Call me a skeptic, but until I see evidence that Dr. Habba's research included the taking of biopsy samples of every patient diagnosed with "Habba Syndrome", (to rule out MC), I suspect that this is just another example of misdiagnosis of MC, due to the failure to take biopsies during a colonoscopy. The "work up" description mentions a colonoscopy to rule out Crohn's and/or UC, but it does not mention the need for a biopsy, and biopsies are not necessary for diagnosis of Crohn's or UC, due to the presence of lesions that are visiable to the naked eye, during an exam with a colonoscope. I could be totally wrong, of course, but without the mention of those key words, "biopsy samples", I can reach no other conclusion from the description at the site you referenced.
The thing that really looks suspicious, is symptom number three, in their symptom list:
Failure to respond to standard therapy of IBS or spastic colon
That makes it pretty clear that MC is totally off Dr. Habba's radar. In fact, all three of the other symptoms listed, also apply to MC. Several members of our discussion board, for example swear by Caltrate 600, (which works by binding bile acid). Another symptom mentions "
fear of eating to avoid diarrhea".

Is there anyone who is a member of this board who can honestly say that they have never had that fear? I don't think so.
I also note that MC can affect the way that the pancreas and the gall bladder function. In fact, we have members who have been claimed, (by their doctors), to have serious pancreas issues, (but those issues cleared up, when their MC symptoms were resolved). We also have at least a couple of members who have had their gallbladders removed due to "major physiological changes" to the walls of the gallbladder, (probably due to an inflammation of the epithelium of the gallbladder, similar to the inflammation that we have in the epithelium of the colon). This was not "normal" gallbladder disease, because gallstones were not the problem, and when gallstones are not present, most doctors will not come up with a diagnosis of gallbladder disease.
At least that's my opinion, until I see evidence to the contrary.
