A living will is a legal document that tells others what your personal choices are about end-of-life medical treatment. It lays out the procedures or medications you want—or don’t want—to prolong your life if you can’t talk with the doctors yourself.
This could be because you’re under anesthesia for a scheduled surgery and had a complication or are unconscious from an accident or other event.
A living will is different than a health care proxy. The health care proxy when you choose someone you trust to make medical decisions on your behalf. The living will is where YOU (not someone else) specifies your preferences.
