I had my gallbladder removed 3so months ago and immediately started with the weight gain which I’ve never been able to put on! After reading and reading and trying what I thought was everything. I went back to my probiotics that I’ve always used for my ibs, within days I noticed a difference! And after gaining about 15 lbs in just my gut, Im very small framed, my tummy is flat and lean again. Its the only thing that helps!! I use the nature made triple probiotic, its about 20 dollars per month but so worth it and I don’t feel nearly as bloated all the time either
