fasting (interpretation of the meaning):

physical weakness, there is nothing wrong with her not fasting in Ramadaan,

Muhammad ibn Saalih al-‘Uthaymeen (may Allaah have mercy on him) was asked:
What is the
ruling on one who breaks the obligatory fast because of thirst?
is that it is haraam for one who is observing an obligatory fast – whether
in Ramadaan or making up a missed fast, or observing an expiatory fast, or
fidyah – to break this fast. But if his thirst is so intense that he fears
that he may be harmed or may die, then it is permissible for him to break
the fast and there is no sin on him, even if that is in Ramadaan, if it is
so bad that he fears he may be harmed or may die. Then it is permissible for
him to break the fast. End quote.
