<div class="PlainText">'The Kaf haChaim 618:1 says that only where the was a cheshash to<br>
begin with, we can use the choleh's determination which way to go on<br>
the cheshash.'<br>
<br>
: Bottom line question: Is it really the case that someone is only a choleh<br>
: in halacha when their doctor says so?<br>
<br>
'As you see, no. But again, the KhC would say you need the doctor to say<br>
the guy isn't just being a hypocondriac, that there is /some/ cheshash<br>
he is basing his fear on. Even if the fear isn't realistic.'<br>
<br>
</div>
<div class="PlainText">Thanks for noticing the deliberate mistake and correcting to OC 618:1 not 518. </div>
<div class="PlainText">From the KhC as you quote him it seems that in fact he is saying that you need the dr to say that there is some chashash, just that it doesn't get to safek pikuach nefesh level, before he can eat by his own estimation. To all intents
and purposes that does mean he's only a choleh when the dr says so, at least as regards eating on YK. </div>
<div class="PlainText">WRT Shabbos, there's no such issue AFAIK. A status of choleh kol gufo, choleh bmiktzas, michush b'alma are all determined by the patient and his symptoms. Medical opinion is only needed when there's a doubt as to whether there's a pikuach
nefesh issue which would require chilul shabbos. </div>
<div class="PlainText"><br>
</div>
<div class="PlainText">Back to the KhC, in practice it's hard to think when you would have a real chashash which doesn't reach safek pikuach nefesh level. Usually if there's a real chashash that's already the kind of safek which would make it hard to say it's
mutar to fast. And if there's no chashash then how is he a choleh?</div>
<div class="PlainText">So still having difficulty fitting the criteria of this halacha, as per KhC, into any modern medical scenario. </div>
