I had two surgeries in the last 6 weeks for kidney stones, and also developed a blood infection (not sure how yet). I was on antibiotics for 5 weeks, IV. 3 times daily at home. Obviously this did not help my IBS D. Now I am having to take more ATBs as a preventive measure until a final procedure in about 3 weeks. These are taken orally and do not seem as strong. Is there something I can do to rebuild my gut microbiota in the mean time? Thanks in advance!
