My mom is 85 years old has severe dementia and blindness. She is DNR and was taking off all meds other than Comfort Care. She developed a severe kidney infection and was put on end-of-life hospice about a month ago for 3 weeks now she does not eat barely drinks anything and I was told she would probably pass within a few days 3 weeks ago. Today she rallied a bit and actually ate a little bit and was more aware. For the last two weeks all she has done is sleep and babble incoherently if you do wake her. She has lost a lot of weight and is surviving solely on perhaps a pudding cup and a glass of juice daily. How can someone survive on so little for this long?
