Hmm, i too feel that he needs more proteins. The other day he had some rash on skin. I immediately took him to the doctor to check it out. We live on the first floor and he had to climb down and then up the stairs. The next day he was complaining of pain in the thighs region (the kind when you squat too much). I guess all this chemo, radiation, surgery have taken a toll on the body. He is weighing in at 60 Kgs. at 5' 8". But all now he has left is fat.
I have started adding Whey protein powder from On Nutrition in his milk shakes, about 150 gms daily. lets see how things go.
And yes, eating really does become a chore for the patient. He has very limited items to eat from, and more over he has to gulp it down with a cough here and there. No enjoying the Food!!
