Irritable Bowel Syndrome Treatment

That’s a possibility if the probiotic is moving some junk out that doesn’t want to be moved. If the person’s intestines are inflamed, then it wouldn’t be surprising if the stuff that was moving out…which is typically pro-inflammatory garbage…did cause a bit of upset.
Usually probiotics don’t cause any problems, but if it’s in the beginning and the stomach cramps are brief, then maybe so.
Good luck and be well.

PS. More than likely, it’s the yogurt that is the culprit. you might stick to taking probiotic supplements.
