SOUNDS LIKE MY HUBBY, THOUGH HE HAS TONGUE CANCER. HE IS ALSO DIABETIC , been looking at high calorie, low sugar/carb meal substitutes today. He only had surgery a week ago, I have been pureeing soups, having him drink Glucerna , Boost etc. But he is a light eater to begin with, lost a few pounds . Been keeping track of calories, 12-1400 0n the average, will be hard to keep over 2, 000! did find a few powders that I think I will try, may become even more difficult after rads. Rads are really scaring me! Had them for breast cancer but what I read ,this is a whole different situation , with a lot of possible side effects. He also was in the midst of getting new partial dentures , when he was diagnosed. Looks like that will be on hold for a long time. With so many teeth already missing, doesn't help. Seems like this whole process is more than either of us expected. Have a surgeons appt tomorrow, maybe he will elaborate. on what I have been reading here!
