Halakhah for Beitzah 43:1

A sick person who is in bed with his illness but is not in danger Rem"a: Or if he has a pain that is bothering him and his whole body pains him, even if he still walks, he is similar to someone bedridden (HaMagid Chapter 2), we tell a non-Jew to provide medical treatment, but we do not violate Toraitic Shabbat prohibitions even if he has an endangered body part. Regarding a Jew actively breaking a rabbinic prohibition, there are some who allow it even if he does not have an endangered body part. There are those who say that if he has an endangered body part we break and if he doesn't, we do not break. There are those who say that if he doesn't have an endangered body part, we desecrate with a slight change, and if he has an endangered body part, we break without a change. And there are those who say that even if he has an endangered body part, we do not break any prohibition that is related to a Toraitic labor, and things that have no connection, we do even if he does not have an endangered body part. This third position is right. Rem"a: It is permitted to tell a non-Jew to cook something for a child that has nothing to eat, because the needs of a child are comparable to a non-endangered sick person. And everything that is forbidden for a Jew to do is also forbidden for the sick person himself to do, but if a non-Jew is doing something, the sick person is allowed to help a bit, because aiding is not considered substantial.
