I don't think restrictive diets are a great idea, because I want to stay healthy otherwise and ultimately restore that balance, but curiously enough, I've found that wheat might be exacerbating some of these symptoms—despite eating it without issue my whole life.
No matter how neutrally and deferentially I approach doctors with this info, I'm treated like a paranoiac for merely inquiring about certain possibilities like so-called SIBO. I'm pretty sure I'd get dragged straight to the loony bin if I ever mentioned parasites.
Sorry for making this about me, but I wrote all this to say: this guy is very lucky he's a medical student. Even with similar evidence, I have a hard time believing he'd get medicine (and respect) as a single mother. The moment she whipped out slides like he did, they'd be writing an antipsychotic Rx.
