If the fasting person detects the taste of blood in his throat

If we detect the taste of blood in out throats and spit out a little
of it when fasting, do we have to make up the fast?.
Praise be to Allaah.
If the fasting person detects the taste of blood in his throat, that
does not affect him even if he swallows it, but if it comes up to the
mouth then he swallows it, he breaks his fast.
The same is said concerning phlegm, sputum and everything that may
appear in the throat.
Shaykh Ibn 'Uthaymeen (may Allaah have mercy on him) said: I should
point out with regard to the issue of sputum and phlegm, because some
fasting people make it toohard for themselves, and if they notice that
in the deepest part of their throats, they try very hardto expel it,
and this is a mistake, because phlegm and sputum do not spoil
aperson's fast unless they reach his mouth then he swallows them, in
which case it breaks the fast according to some scholars, but
according to others that does not break the fast either.
But that which is in his throat and goes down into his stomach does
not break his fast, even if he feels it, so he should not tire himself
out by trying to expel that which is in his throat of these things.
