> Doctors don’t really care to look at these kinds of issues. It took years of suffering and autoimmune issues (particularly muscle spasms and joint pain) alongside gut problems before I demanded a gastroenterologist test me for H pylori and SIBO: I was positive for both.

I went through a similar post-antibiotics gut nightmare. There are good doctors and there are bad doctors and like everything, there are fewer good ones than bad+average ones.

Seems like you got testing and treatment eventually, I'm sorry it didn't work better; I'm replying less for you and more for anyone who encounters similar. Shop around for your docs!

I got tested very quickly for both H Pylori and SIBO in 2019 on doctor suggestions, I'd never heard of either. Sounds like this was probably around the same time as you went through this based no the antibiotic course that messed up your gut being in 2017).

I went to three doctors in six months, the one that did the testing was the second one. The one who was confident in their knowledge but didn't do anything, including the testing -> immediate no-return-visit from me. The one who said "we don't really know how this works" but also didn't do anything -> no return visit, but appreciate the candor. The one I went back to is the one who said "we don't really know how this works, but let's test for these other things we've learned more about recently, and let's also try some experimental/off-label things." I was actually negative for both of those things, so there was even more random stuff beyond that, but the only one the doctor I liked was really resistant to was a poop transplant, though personally... seems like the only known way to repopulate some of the shit, pun intended.
