Hello,
I had surgery in 04 and went throught the same thing. Sometimes I would smell food and get sick to my stomach. Meat was out of the question. I started by eating small bites of cold food. I could never tolerate Ensure, I would have diahrea within an hour. I lost 32 lbs. One day I decided that if I was going to live, I had to eat. So I told my husband I wanted one or two bites of something loaded with calories or protein every hour. Thats the way I started. Sometimes it would be ice cream, sometimes it would be a bite of cheese. Sometimes I would ask for something and I would change my mind before he got it to me. What a jewell he is to put up with me. Now I can eat much more, I was 64 at the time, I am now back at work (Youwould think I would be smart enought to quit, but I am so grateful for my energy that I love work) I have gained 15 of those lost lbs back, I have clear CT's and I still eat very small amounts, but much more than I used to. Food still doesn't taste like it did before surgery, but much better than it did when I was going through your dads present stages.
Please pass this on to your dad and tell him this will get better, but he must get some calories of some kind. Good luck. I will pray for him and everyone who loves him, most especially you.
