The rise of doctors describing functional or psychogenic symptoms as "not real" symptoms should genuinely disturb everyone.
It harms those with functional/psychogenic symptoms, because yes, the symptoms are real, regardless of a lack of organic cause. They aren't lying or faking them, they're just not organic in nature.
And even if you don't give a shit about individuals with those types of symptoms (you should), it should still worry you if you're disabled, especially if you're a part of another marginalised group (especially women tbh). You're more likely to be assumed to have functional/psychogenic symptoms, and if doctors believe you do, they won't test for other stuff, or only do very basic tests. Like having any kind of functional/psychogenic diagnosis or suspected diagnosis on your records will hinder any other attempts to seek medical help because everything gets blamed on that, even if (like me!) you have proof that there's other stuff going on (eg positive test results). This means that you can be very definitely physically organically ill, and still be refused tests and treatments based on assumptions.
And then when those symptoms get labelled as "not real"...well, suddenly those with functional/psychogenic problems are basically being called liars, fakers, etc, and can't get the help they need to a, recover/improve, and b, get the support they need whilst/when they have symptoms. (And hey, guess what, if you have neither of those things, you're not gonna get better and may in fact get worse!) And those who've just been assumed to have them are going to get labelled increasingly as liars and fakers as they get increasingly sicker from the "not real" symptoms, risking long term damage from the "not real" symptoms.
(Post inspired by a conference I went to in which an actual doctor stood up in front of hundreds of people and described how it's hard to tell if a teenage girl with anxiety has real stomach pain or not. Because if your stomach hurts from anxiety, it's actually fake, the pain doesn't exist I guess.)
