Hi there,
My dad has also lost a lot of weight...The hospital nutritionist spoke to us today...they're giving dad a feeding tube...does your husband have one?
There is also something called benecal that is just 1.5 oz of a liquid that you can add to whatever he eats or drinks..it has no taste...it adds 350 calories...so its worth the effort to add it.
Hope this helps...hang in there...
Angie
