My father had esophagus cancer some eight years ago and lost a lot of weight. He can only eat small amounts at each meal and almost everything causes sever acid reflex. As a result he has conditioned himself to only eat those things that don't cause him pain, all of which have no nutritional value.
Now his appetite is decreasing and I fear he will stop eating all together. I thought if I can increase his appetite we could possibly get some weight on him.
