Hi. My father is 83 and is in the final stages of dementia. He hasn't walked for over 2 years and hasn't talked for over 5 years. He is on oxygen all the time and is also diabetic. He has had a couple of close calls when they thought he was dying as his skin was mottling, but then bounced back 2 days later. He is on "comfort" care only, started by my mom. My mom has died, and I am dad's POA and his medical proxy, I guess you call it. He has lost 9 pounds in a month as he has problems swallowing. Should I have his meds discontinued, or is the diabetes medicine considered "comfort" care? I certainly don't want to do anything unethical, but he is sufferering and I know he won't ever get better. Thanks.
