My husband's aunt (who he has Medical POA for) is nearly 96 years old. Seven months ago she had to be moved to a SNF following a UT infection and fall. At the time she was very malnourished. She was living alone and is very reclusive. She improved and gained 10 pounds, but has now declined a bit, has some swallowing issues and the Dr. prescribed an appetite stimulant. She has mild dementia and has expressed that she doesn't know why she is "still here". We both feel she is ready to die and that not eating may be her way of dealing with it. Any suggestions? she made here wishes know several years ago that she did not want any life prolonging measures, would this be considered that and eventually lead to feeding tubes, etc.?
