So I just spent 4 days in the hospital due to bowel obstruction. I will put this out here as purely my experience, but perhaps a cautionary tale.
I had eaten a full bag of shirataki noodles with my dinner, about 7 oz per night, two nights running. Ordinarily I’ve had no digestive problems with shirataki, but I had rather extreme diarrhea at the same time I was ingesting this. I believe the diarrhea was incidental and caused by something else, but I would have been quite dehydrated.
I woke up on Thursday morning with excruciating gut cramps. Eventually wound up in the emergency room. CT scan revealed obstruction, which in this case was basically a very tight oxbow cutting off blood circulation and making passage of any matter impossible. Surgery and several days later I’ve been released from the hospital and doing just fine.
My surgeon insisted that anything about my diet would have had no impact on this. I asked him if he knew what shirataki noodles were. (Basically a giant mass of indigestible, insoluble fiber, especially if taken with insufficient hydration. A gigantic mass of fiber actually outlawed in some forms in Australia primarily because of bowel issues it can cause.). He said no, but it didn’t matter.
This pretty much lines up with my opinion about big med. If it’s not in the book and they didn’t learn it in med school, it’s irrelevant. Now I’m not saying I didn’t have some sort of obstructive issue to begin with. But honestly, the timing of my intake and the abrupt distress afterward are too coincidental for me to dismiss, personally.
In any event, still love shirataki but will definitely consume in smaller quantities and with great care about hydration in the future. 
. The amount of emotional trauma through high school and college that could have been avoided, not to mention nostrums potions lotions makeup and later life scars, if I’d just listened to myself …
