Diane, watch that weight loss!!! This is very early for that kind of drop. My nurses told me the goal is to have zero weight loss but for most patients its impossible. By losing weight so quickly a person loses muscle which makes them feel run down. This very quickly turns into a viscous cycle where he will struggle and possibly end up hospitalized for malnutrition/dehydration. It happened to me so please change this now so he doesnt go thru that experience.
Push the nutrition! Every single day a minimum of 3000 calories and 48 oz of water. Boost now makes the Very High Calorie (VHC) drink which can be found on thru Amazon. By going thru OCF for this you will be helping us to help you. It give OCF a 6% kick back, this goes for anything you purchase there. Here is a link to the thread for VHC that Brian set up to have our info already there so OCF gets the kick back. By drinking VHC he would only need to get 6 of them in per day to hit his calories.
Bost VHC (with the OCF Amazon link built in) PS.... There is always the nasal tube or a regular feeding tube which could be added if necessary. No matter what he must swallow every single day even if it hurts. If he is in alot of pain, talk with the doc about pain meds like the fentanyl patch. Good luck!!!
