Again most doctors don't get this because they are not that great at metabolic endocrinology, most of the research is recent, and because acid reflux does irritate the throat, they do not look for a common metabolic cause, they just treat the acid reflux and get stumped when that doesn't clear up
So here's the experiment - eat a big meal - you get mucus
, maybe acid reflux or heart burn.
Eat a high carb meal. same result.
