How long can mom go on fluids only?

wow , very surprised to hear how long some have gone without eating. mom has advanced RCC , mets to the lungs. She has always known the importance of eating for strength, now it just upsets her when I try. she was taking 4 shots per day, now because of not eating I am afraid to give her any. Sugar readings are high, I know it is not from food but maybe stress on her body, pretty confused on what to do.

Mom did that for a couple of months and then bounced back and started eating again. Its been off and on like that for nearly 3 years now.

I forgot to tell you that was a year ago. She eats well now.

This is worth talking to the hospice nurse about. Going with only fluids could go on a long time, but if she is on hospice other factors will come into play.

My husband ate a good breakfast the day he died. Ability/desire to eat is only one of several end-of-life indicators.

I am not sure about the boost. But my mom is still alive after being without food for more than55 days all she drank was root beer. Tha was after they told us she would die in two days. She is 97years old
