My grandma is dying and her doctor and my uncle, who is also a physician, wants to remove her feeding tube. Is this morally acceptable?
My sympathies are with you and your family during this difficult time and we ask our forum participants to keep your grandmother, you, and your family in their prayers.
For medical bioethics questions, I strongly recommend that you or your uncle contact the National Catholic Bioethics Center. They are more qualified than am I to answer your question. God bless.
