The symptoms of sterile gut are.....unpleasant. Diarrhea, gas, etc. It’s caused by the loss of intestinal flora, due to being killed of by something (in my case a course of antibiotics). This floral “shift” causes pH shifts, and other things that your guts don’t like. Now, as to the cure....it’s more of the good bacteria that likes to live in your GI system. Now some regimens involve actually ingesting pills with those bacteria in them (poop pills?). I hardly think that would be necessary as we are continually exposed to these bugs in our daily life. Your intestines will eventually be dosed with the proper bacteria to repopulate your system.
Now remember, you asked. A gastroenterologist (GI doctor) would give a better description no doubt, but what I’ve provided is “a quick and dirty”, so to speak. ;-)
Thank goodness for those little bugs. Without them, what would we do?
