I went through my entire childhood without ever getting sick enough to need antibiotics. Then, I managed to catch strep in my early 20s, and went on a course of antibiotics to take care of it.<p>This is of course purely anecdotal, but the following year was pure hell from a digestive system standpoint, and looking back, I&#x27;m pretty sure it was tied to that course of antibiotics. Thankfully, things cleared up on their own, but I&#x27;d definitely be looking at probiotics if forced to go on antibiotics again for some reason.<p>Glad to see research on this topic.
