I jumped in on this thread due to my recent symptoms. I normally post on the Constipation threads, since I’ve had chronic constipation since the summer of 2022, except it left a few weeks ago, as I reported on the constipation thread. I had tried almost everything to go….diet, water, prescription pills, Metamucil, Miralax, etc. I did go with daily Miralax, but was like jello. Ugh….so, I was delighted when after being on Vitamin B12, per my Neurologist’s instruction, the constipation left and my BMs were normal again. UNTIL this past Sunday when I had diarrhea twice in one day. Then normal….then loose BM last night! Granted, I have been very heavy on salads lately. Almost daily I have a large plate of lettuce, tomato, apples, cucumbers, blueberries, shredded carrots and beets. Then more cooked veggies ( broccoli and cauliflower) at dinner. I don’t eat much wheat. I’ve had extensive autoimmune tests and am cleared. Negative for celiac. I do have type 1 diabetes.

Think I’ll ease up on the raw veggies and see how that works. I’ve also read that high doses of B12 can cause diarrhea. I have to stay on that though due to deficiency. Hmmm….hope it’s not that.
