@jakofin I asked my Mayo Clinic Integrative Medicine physician the question about probiotics today. While she sees patients the majority of her time is spent in research. She told me the following. In research, the amount and type of probiotic is very specific. It's next to impossible to replicate what is in the research to any OTC probiotics. In addition, there is tremendous variability among these products. She advises her oncology patients against any probiotics during chemotherapy because chemo lowers the immune system. If you introduce any probiotic (basically a gut bacteria) this can introduce a "bug" into one's system that your immune system cannot fight off. For radiation therapy, the goal is try and reduce diarrhea. My Integrative Medicine physician said that how much and how often one experiences diarrhea depends on the size of the field - just how much of the pelvic area is being treated with radiation. She recommends that her patients eat more fiber as in vegetables as the fiber will help to offset the diarrhea. She also said that eating yogurt every day can be helpful.

Does this help? If your treatment includes chemotherapy you might like to run this past your oncologist.
