Is it permissible to expose one's 'awrah to a non-Muslim man/woman out of necessity for the treatment of hemorrhoids?

It is permissible for a sick person to present themselves to a non-Muslim doctor to expose their awrah for treatment, according to the consensus of the people of knowledge, provided that no more of the awrah is exposed than what is necessary. It is not permissible for a woman to expose herself to a female doctor if a male doctor is available, even if he is non-Muslim, because necessity permits it, and this should be in the presence of a mahram or husband, with the condition that there is no woman available who can provide the treatment.
