I am in agreement with the previous poster. With what you have ahead of you, you will have a hard time taking things by mouth after the first couple of weeks of radiation when the mucocitis really starts to set in. More than that, you are missing the primary reason for getting a PEG tube, and that is to keep up your nutrition. Even if your body has excess weight as you say, it is likely not excess muscle tissue but adipose tissue. As your body undergoes the cellular destruction from the treatments, it needs proteins and amino acids to rebuild the damage each day. The results of poor nutritional intake will be slower healing and the loss of lean body mass (muscle tissue) which is made up of proteins and amino acids. Read the many many posts here on this subject using the search engine on the message board. It really is something that few people can get through this without.
