Very interesting! Thanks for sharing.
The gut microbiome changes significantly day-to-day, and sampling differences can affect the results enough that meaningful insights are almost impossible from a single gut microbiome test.
That said, you might be able to tease out a few interesting takeaways. I couldn’t find in your post an overall phlyum-level summary (what % is Firmicutes/Bacteroides/etc), but that’s the first place I would look. If that is significantly out-of-whack, or if another phylum is very dominant (e.g. one of the the proteobacteria) then I would take that as a clue that something is odd.
How severe was your COVID infection? I assume you weren’t hospitalized, so perhaps this is not relevant but I would look for evidence of Enterococcus faecalis? This seems to be a predictor of COVID severity.
Your action plan seems sensible to me. I would suggest that you also consider a water-only fast for 2-3 days. If your gut is accustomed to a lifetime of regular meals, a short fast can give some of your underrepresented microbes some time to come to the surface and improve your overall composition.
