Thank you to everyone that responded. It really helps to know that what he is going through is normal and that he will get better. I wish we would have been more prepared for the length of recovery time. The reason he did not have the nutrition earlier is that the doctors kept telling him he would feel better a few weeks after radiation. He figured he could stand to lose a few pounds and the doctors did not push it. It wasn't until he was hospitalized that they began to address it. My husband said he didn't want a stomach feeding tube and they said okay to giving TPN through the Mediport. We really didn't know anything about feeding tubes and thought it was only reserved for the worse-case scenario patient. Now I see on the site that nearly everyone had one.
