Thanks so much for all the advice, "way to gos", and support. Dad's surgery went well, he's in his hospital room now. In very little pain, and able to ambulate well.
Dr. said his stomach was bigger than most that he sees, so he feels this will be tremendously helpful for him. He's positive today, and looking forward to the future.
I appreciate the thoughts on "not wanting others to hide what they eat" or "protecting him" these are good thoughts - and reassures us of what we were already thinking.
So thanks to you all - and I wish you all continued success!!
