<human>: My grandfather has dementia and Parkinson's that has left him bedridden for the past two years. He has lost the ability to swallow, so she had a gastric tube (a tube placed directly into his stomach) placed and feeds him formula that way. She did this despite all her children, grandchildren, and her even the doctor saying that she shouldn't. She doesn't want to remove the gastric tube because she doesn't want to "just starve him." However, I think he could be sedated so he doesn't feel anything, but she doesn't want to hear it. My grandfather was a independent and prideful man and I think he would be humiliated at the thought of his children and grandchildren changing his diaper every 2 hours. He only responds to pain at this point and keeping him from getting bed sores is a constant battle. It looks like torture and my grandmother seems to be the only person that can't see how miserable he is. I need help getting her to understand that this isn't the way he would have chosen to live. Thanks for any help you can offer, reddit.

Can you give me a shortened version of the text?
<bot>: My grandmother is keeping my grandfather alive even though my grandfather is in pain, despite everyone else's urges to let him go.
