Kelly, while I appreciate the situation you find yourself in, your father needs to get his priorities straight. Not wanting a feeding tube and becoming so weak that treatments (which may save his life) have to be stopped, is irrational. You need to try to move him in the direction of the PEG. At most treating facilities it is not a patients choice to have it or not. If you lose 10% of your body weight you get put on the tube. He is way past that point. He will not heal properly without good nutrition and plenty of it. He will continue to get dehydrated. It is clear that he isn't going to be able to get down enough calories without it. With the tube taste is a non-issue, and that will eventually come back when he gets through all this anyway. When his treatments pick up again the mucositis sores in his mouth are only going to get worse until several weeks after the end of treatment, so his ability to swallow and tolerate eating in a conventional sense is going to be even more limited. If you cannot convince him, you should speak directly to his doctors and voice your concerns...they will dictate that he gets one put in. Stopping treatments is not the right path.
