My mother passed away after her battle with Altzheimers. At the end, she refused food (believe me, there was no way to get anything past her clenched teeth!). We decided not to have a feeding tube inserted. Yes, she would of remained alive, but my "Mom" wasn't alive.........only her shell was there. It took maybe a week for the end to come. No, she was not in any pain and didn't require any medication. She slipped away peacefully in her sleep. And NO, she did not "wither" away. I'm not saying you won't see weight loss on Terri, she's is much younger than my mom and a larger woman that my mom. My mother's physical appearance did not change in her last week.
I have a bit of understanding when it comes to the feeding tube. My DH required one from Sept. to Jan. of this year after the battle with cancer left his throat so burned from radiation that he was not able to swallow without extreme pain. The tube is inserted into the belly and held in place by what looks like a mushroom on the end inside the stomach (I had to see this when they pulled it!!). Now, according to what the doctor told us was that when he pulled it that day, if they needed to reinsert it again, it would have to be done by surgery (opening up the belly). They are able to insert it once through the laproscopy, which is how he was inserted. If they decide to place Terri's again, I can only assume it will be the same way. The tube they showed on Terri was the exact one my DH had.
A bit off the main topic but I heard a priest say that only God should decide when a person's time has come. Well, if you think about it, God DID decide. The stroke Terri had 15 year ago left her with the inability to take in nutrition. Medical science stepped in to keep her alive. Sounds like a double standard. This woman deserves to be able to finally rest.
