Mom is 81 & has gastroparesis (from hernia surgery) & feeding tube which keeps clogging. She is malnourished since liquid nutrition isn't working & health is rapidly declining. She is in hospital for 4th time to unclog tube & doctors have run out of options. She is very weak & has no advance directives. Our hearts are breaking but we are now at the point that if tube clogs again, do we unclog or just let nature take its course. Anyone have experience?
