The problem with probiotics is your guessing. some are actually promoters of inflammation.
From my experience I will never take them again. three times i've tried and all three times I've felt horrible.
since i was devoid of lactobacillus, from stool sample testing, made sense to start there. went one step further, started on lactobacillus plantarum, as research has shown it to have a positive effect on intestinal inflammation. and then, to me, the true test, does it work. for me, the answer was a big yes. then a few more added in by the advice of the GI doc. don't know if i need all three, but things are better with them, than without, thus i stick with it.
but if they made you worse, then by all means, it wasn't the right thing for you, at least not the specific ones you were on.
I dont doubt our disease begins in the gut.
When I had my remission with the iniation of enbrel my gut was the first thing I noticed functioned perfectly.
that was my reaction to the 6 day pred taper. 3 days in, and the constipation was completely turned around! its been a few weeks, "knock on wood", things remain good for the time being.
