I actually like the name PAS, it's just that a lot of us don't have PA.
I'm a member of a society for something I haven't got
Which GPs, friends, family and anybody else are only too willing to point out.
"Ahh, but it's the Pernicious Anaemia Society and you haven't got that, therefore there is nothing wrong with you other than a bit of a vitamin deficiency and you can buy that stuff from the health food shops..."
I mean, the whole thing is a mess. Not the PAS name, just the diagnosis, treatment, definition...everything.
You start explaining to somebody about PA. Then you tell them you haven't got it (but miss out the bit that says a future test might prove you do actually have it) Then you explain about the blood tests and they ask about the normal range. Then you have to explain that although the ranges can appear normal in fact many are not because our ranges are too low. Then you have to explain about when ranges are normal but people are still sick because there are inactive and active forms of b12. If they eventually get that you then have to explain that although the active b12 might be available to the body it can't be used because something is stopping it. What? they ask. Hmm. In many cases we don't know, and, even in cases where we do know like mine (hyperchlorhydria) doctors have never even heard of it.
You can see them looking at you like you're the world's biggest numbskull thinking: Don't be stupid. Modern medicine can't be THAT wrong.
If we could at least start with a name that clearly defines the problem, like Andrea's suggestion of Classical PA, then Types 1, 2 etc, we'd at least have a fighting chance.
I mean, if somebody tells you they are diabetic you get it immediately. They don't have to launch into an interpretation as per above. You know they have a clearly defined medical problem.
