i have seen many gastroenterologists
my conclusion is that just about
all of them are surgeons (its where the money is) and these typically have only a very rudimentary understanding, at best, of the subtle and complex things happening in the gut. At worst they are like plumbers that only know how to take bits of pipe out and cobble the ends together!
i have tried to get an appointment with a functional gastroenterologist - but my provider just sent me to another surgeon - and i got the usual CAT scan, endoscopy, colonoscopy and pronounced to have no structural issues and it must therefore be a functional issue (no crap sherlock!) - and "not my department I'm afraid"
i wonder how inflamed things would have to be to be able to see it - eg if you have lots of stool test markers for gut inflammation - calprotectin, lactoferrin etc - would it look normal or look red and inflamed to the naked eye ?
i don't think it needs to be a rampant invasive fungal growth ( like you see on catheters ) to be causing harm - and i wonder what is showing up on OAT tests as fungal markers - if its not a thing
so i am pretty sure it is a thing - just not sure what would be there to see by naked eye for the plumber.

the paper has pictures of what invasive candida of the oesophagus looks like and mentions some of the symptoms "Immunocompromised patients are most at risk, including patients with HIV/AIDS, leukemia, diabetics, and those who are receiving corticosteroids, radiation, and chemotherapy. Another group includes those who used antibiotics frequently and those who have esophageal motility disorder (cardiac achalasia and scleroderma). Patients complained of pain on swallowing, difficulty swallowing, and pain behind the sternum. On physical examination, there is a plaque that often occurs together with oral thrush. Endoscopic examination is the best approach to diagnose this disease by directly observing the white mucosal plaque-like lesions and exudates adherent to the mucosa.!"
