EVERY time one's gut gets borked simply take a good probiotic with a mild meal ( that the good microbes will like ), and in about 2+h your gut is fixed.
Look for a probiotic with multiple Bifido strains & multiple Lactobacillus strains & Subtilis if you can find that too ( there is a PubMed item on how adding Subtilis to agricultural animals reduced their sickness/infection rate, and since we're mammals too, I'm presuming that we work similarly )
Also use a probiotic after any course of antibiotics, to fix-up one's gut.
I'm old, and find I need the things more frequently, now: even too-much salt in a meal can wreck my gut, but if I'm careful, then I don't need the help.
