Hi Cathy. I've taken a probiotic since early May of this year. I've noticed a marked improvement but I'm existing without my lower colon, which was removed due to cancer. I experience multiple bm's per day and IBS-like symptoms now. The probiotic I'm on seems to quiet my gut, the rumbling and heaving is to a minimum and the stool is more consistent. The one I'm on I highly recommend - Renew Life, Critical Colon, 80 Billion Count, found at your local health food store in the chilled section near organic yogurt, flax seed oils, etc. Somewhat pricey though, #30 count bottle runs me $47.00 but I sometimes find a $5 off coupon. That helps. The only thing I have noticed about this probiotic is sometimes it seems as if I need a double dose. What I took back in May doesn't quite seem like enough on my bad days. So it doesn't seem to make things worse but I don't always see the huge improvements I saw early on when I first started taking it. It never hurts to take it, so no in a wordy way I don't think this particular probiotic makes things worse for me.
What specific probiotic are you taking?
